History: Building Ogre3D 1.9 Statically in Mac OS X (Yosemite)

Source of version: 110 (current)

The purpose of this guide is to help developers that have been working in other platforms (i.e., Linux, Windows) using mainly C++ and are not familiar with XCode nor ObjectiveC, but have a lot of desire to work with Ogre3D in Mac OS X. Additionally it would help other developers that wish to work with QtCreator and CMake. 


{maketoc}

! Prerequisites
*You need to have a basic C++ background.
*Basic knowledge about how to use a terminal in Mac OS X (create folders, list directory contents, run commands, etc.).
*An Internet connection (this sounds obvious, but it’s better to clarify :) ).
*Have the following software installed (there are no specific restrictions regarding the versions used, but it's better to use the latest):
**Xcode.
**Mercurial.
**QtCreator.
**CMake.   
*When this tutorial refers to the __terminal__, it's refering to the __Mac OS X Terminal__.
*When entering a command in the terminal, this tutorial refers to the current path location with the following notation:  
{CODE(ln=0, wrap="1", colors="c++")}
$> cd /folder1/folder2
/folder1/folder2 $> pwd
/folder1/folder2
{CODE}
---
! Building Ogre
First, create a folder where the whole Ogre3D project will live:
{CODE(wrap="1", colors="c++")}
$> sudo mkdir -p /opt/dev
{CODE}
You can create this folder in another location if you wish. This is not a blocker. The important thing is that you keep in mind where the folder was created to use it from now on.

!! Downloading Ogre3D’s Dependencies
Create the folder where the dependencies will reside:

{CODE(wrap="1", colors="c++")}/opt/dev/ $> mkdir dependencies{CODE}
Go to the following link and download ogre3D’s dependencies:

http://sourceforge.net/projects/ogre/files/ogre-dependencies-mac/1.9/OgreDependencies_OSX_libc%2B%2B_20130610.zip/download

Unzip the file you downloaded. This will contain a folder called __Dependencies__. Copy the content of that folder to the following location:

{CODE(wrap="1", colors="c++")}/opt/dev/dependencies{CODE}
You should have something like this:
{IMG(fileId="2214",rel="box[g]")}{IMG}
These dependencies include:

*__Boost: __It’s a set of open source libraries that extend the functionality of C++.
*__Freeimage:__ it’s an Open Source library project for developers who would like to support popular graphics image formats like PNG, BMP, JPEG, TIFF and others as needed by today's multimedia applications.
*__Freetype:__ It’s is a freely available software library to render fonts.
*__OIS:__ It’s a code library for constructing a human-computer interface with input devices such as a keyboard, mouse or game controller.
*__zlib:__ It’s a software library used for data compression.
*__zziplib:__ it offers the ability to easily extract data from files archived in a single zip file. 
The previous downloaded dependencies are static libraries (end up with the extension __.a__). Normally in other platforms when you build a library for 32 and 64 bits you end up with two different library files (one for 32 and other for 64). Here in Mac OS X, you can build for 32 AND 64 bits and you end up with a single file. That single file is what is called a “flat” binary or a “universal” binary. In order to check if a library is for 32 bits or 64 bits or both, just run the following command in a terminal:
{CODE(wrap="1", colors="c++")}/opt/dev/dependencies/lib/Release $> lipo -info libOIS.a
Architectures in the fat file: libOIS.a are: x86_64 i386{CODE}
!!Downloading and Building Ogre3D
it’s always better to use the latest stable version from the project’s repository. To do that you should use Mercurial (Mercurial is a distributed version control system). To validate if Mercurial is installed correctly, in a terminal write:
{CODE(wrap="1", colors="c++")}$> hg
Mercurial Distributed SCM

basic commands:

 add           add the specified files on the next commit
 annotate      show changeset information by line for each file
 clone         make a copy of an existing repository
 commit        commit the specified files or all outstanding changes
 diff          diff repository (or selected files)
 export        dump the header and diffs for one or more changesets
 forget        forget the specified files on the next commit
 init          create a new repository in the given directory
 log           show revision history of entire repository or files
 merge         merge working directory with another revision
 pull          pull changes from the specified source
 push          push changes to the specified destination
 remove        remove the specified files on the next commit
 serve         start stand-alone webserver
 status        show changed files in the working directory
 summary       summarize working directory state
 update        update working directory (or switch revisions)

use "hg help" for the full list of commands or "hg -v" for details
{CODE}
To download the Ogre3D's code, write in a terminal:
{CODE(wrap="1", colors="c++")}$> cd /opt/dev
/opt/dev/ $> hg clone https://bitbucket.org/sinbad/ogre ogre3d-1.9.0{CODE}
The last part of the previous command (__ogre3d-1.9.0__) will be the name of the folder where the source code will be downloaded. The download process will take something like 20 minutes (although it depends of your Internet connection).
If everything went okay, the folder should be around 460 MB:
{CODE(wrap="1", colors="c++")}opt/dev/$> du -sh /opt/dev/ogre3d-1.9.0/
461M	/opt/dev/ogre3d-1.9.0/{CODE}
Now it's time to build Ogre3D statically (before running the __cmake__ command, validate that your paths are consistent. After that, just build):
{CODE(wrap="1", colors="c++")}/opt/dev/ogre3d-1.9.0 $> mkdir build
/opt/dev/ogre3d-1.9.0 $> cd !$
/opt/dev/ogre3d-1.9.0/build $> cmake -DCMAKE_CXX_FLAGS="${CMAKE_CXX_FLAGS} -v -stdlib=libc++ -std=c++11" -D BOOST_ROOT=/opt/dev/dependencies/include/boost -D BOOST_INCLUDEDIR=/opt/dev/dependencies/include/boost -D BOOST_LIBRARYDIR=/opt/dev/dependencies/lib -D OGRE_DEPENDENCIES_DIR=/opt/dev/dependencies -D OGRE_STATIC=1 -D OGRE_BUILD_SAMPLES=1 -G Xcode ..{CODE}
Here is the explanation for every parameter:
{FANCYTABLE( head="__Parameter__|__Description__")}
CMAKE_CXX_FLAGS="${CMAKE_CXX_FLAGS} -v -stdlib=libc++ -std=c++11”   |   Defines support for C++11.
BOOST_ROOT=/opt/dev/dependencies/include/boost|   Defines the location of the Boost base folder.
BOOST_INCLUDEDIR=/opt/dev/dependencies/include/boost|Defines the location of the Boost’s include folder.
BOOST_LIBRARYDIR=/opt/dev/dependencies/lib|Defines the location of the Boost’s library folder.
OGRE_DEPENDENCIES_DIR=/opt/dev/dependencies|Defines the location of the Ogre3D’s dependencies folder.
OGRE_STATIC=1|Defines that Ogre3D will be built statically. 
OGRE_BUILD_SAMPLES=1|Defines that the Ogre3D’s samples will be built.
-G Xcode|Specify a makefile generator (Xcode in this case).
..|The couple of dots indicate the location of the CMakeLists.txt file (which is the file that cmake needs to create all the make files). 
{FANCYTABLE}
After building Ogre3D's makefiles with CMake, look for the OGRE.xcodeproj file:
{CODE(wrap="1", colors="c++")}/opt/dev/ogre3d-1.9.0/build $> ls -l OGRE.*
OGRE.build:
total 0
drwxr-xr-x  5 USER  wheel  170 Dec  8 19:14 Debug
drwxr-xr-x  6 USER  wheel  204 Dec  8 19:22 Release

OGRE.xcodeproj:
total 5400
-rw-r--r--  1 USER  wheel  2763182 Dec  8 19:05 project.pbxproj
drwxr-xr-x  4 USER  wheel      136 Dec  8 19:14 project.xcworkspace
drwxr-xr-x  3 USER  wheel      102 Dec  8 19:14 xcuserdata{CODE}
The __OGRE.xcodeproj__ file is the Xcode project configuration file for the Ogre3D’s construction. Go to Finder and double click over that file. This will open Xcode.

__Note: __This tutorial will use Xcode only to build Ogre3D. Afterwards you’re not going to use it anymore.

This is what you’re going to see when Xcode opens with the Ogre3D project:
{IMG(fileId="2215",rel="box[g]", thumb="y")}{IMG}
Go to __Product__ → __Scheme__ → __Edit Scheme..__ and change the __Build Configuration__ to __Release__:
{img fileId="2216" thumb="y" rel="box[g]"}
Select the __install__ scheme and change the __Build Configuration__ to __Release__:
{img fileId="2217" thumb="y" rel="box[g]"}
Select again the __ALL_BUILD__ scheme:
{img fileId="2218" thumb="y" rel="box[g]"}
Close the dialog by clicking the __Close__ button. Now in order to start the building process, in the main menu select __Product__ → __Build__ or press __Command + B__. 
To view the building log, select __View__ → __Navigators__ → __Show Report Navigator__. The building progress can be viewed in the blue progress bar in the Xcode’s top center window area:
{img fileId="2219" thumb="y" rel="box[g]"}
The whole building process is going to take something like 20 minutes in a computer with Processor: 1.3 GHz Intel Core i5 and Memory: 4 GB 1600 MHz DDR3. 
When the building process has finished, select __Product__ → __Scheme__ → __install__. Then __Product__ → __Build__.
After installing Ogre3D, you should have the following folder:
{CODE(wrap="1", colors="c++")}/opt/dev/ogre3d-1.9.0/build/ $> cd sdk
/opt/dev/ogre3d-1.9.0/build/sdk $> ls -l

!!Running the Ogre3D’s Samples
Now that the building process has finished you can run the Ogre3D’s samples. Open the following file in Finder:
{CODE(wrap="1", colors="c++")}/opt/dev/ogre3d-1.9.0/build/bin/Release/SampleBrowser.app{CODE}
You should be able to see the sample browser application called __SampleBrowser.app__. Additionally, you can see the sample browser’s log file in the following path:
{CODE(wrap="1", colors="c++")}/Users/YOURUSERNAME/Library/Application Support/Ogre/Xalafu/ogre.log{CODE}
---
!Using QtCreator
Now that Ogre3D is finally compiled, let’s take a look at the IDE that we’re going to use during this tutorial: QtCreator. This IDE includes the following features:
*Cross-platform.
*Also used for projects non-related to Qt (Qt is a cross-platform application framework).
*Visual Debugger.
*Support for CMake.
*Excellent Vim plugin.
*Good integration with tools: Git, Subversion, Mercurial.
{REMARKSBOX(type="note",title="Note",close="n")}For this tutorial you don't need to download the whole Qt SDK, only the QtCreator application.{REMARKSBOX}
Before using QtCreator for the first time, you need to create a __Build Kits__ in QtCreator (assuming that you just have installed QtCreator and don’t have any __Build Kits__ configured). Open QtCreator's preferences or simply hit __Command + __. On the left panel select the __Build and Run__ option:
{img fileId="2220" thumb="y" rel="box[g]"}
Select the __Add__ button (on the upper-right side). A sub-dialog will be shown, fill the Kits name information:
{img fileId="2221" thumb="y" rel="box[g]"}
!!Creating a Project  (that will use CMake)
From the __File__ menu select the option __New File or Project…__. You will see a dialog like this:
{img fileId="2222" thumb="y" rel="box[g]"}
Select the option __Non-Qt Project__ from the Projects list and subsequently select the __Plain C++ Project (CMake Build)__ option. Afterwards click the __Choose…__ button (located at the bottom-right side of the dialog). Afterwards set the project’s name and location:
{img fileId="2223" thumb="y" rel="box[g]"}
The information used for this tutorial in the previous dialog (the folder __ogreprojects__ was created beforehand):
{CODE(wrap="1", colors="c++")}Name: tutorial1
Create in: /opt/dev/ogreprojects{CODE}
Then click the __Continue__ button. In the following dialog select a version control if you are going to use one. This tutorial won't use any:
{img fileId="2224" thumb="y" rel="box[g]"}
Then click the __Done__ button. You now need to define the __Build Location__ folder in the following dialog:
{img fileId="2225" thumb="y" rel="box[g]"}
The information used for this tutorial in the previous dialog: {CODE(wrap="1", colors="c++")}/opt/dev/ogreprojects/tutorial1/build{CODE}
Click the __Continue__ button. In the following dialog you will run the project’s cmake configuration file. Click the __Run CMake__ button and you should see something like this:
{img fileId="2226" thumb="y" rel="box[g]"}
{REMARKSBOX(type="note",title="Note",close="n")}Validate that you’re not getting any RED warnings in the previous output dialog.{REMARKSBOX} Now hit the __Done__ button and you will see the template code that QtCreator has created for you:
{img fileId="2227" thumb="y" rel="box[g]"}
From the __Build__ menu select the __Build All__ option. The __Compile Output__ window (located at the bottom) will tell you the building information. If everything went okay, from the __Build__ menu select the __Run__ option. You should see the programs output in the __Application output__ (located at the bottom) window:
{img fileId="2228" thumb="y" rel="box[g]"}
!!Integrating Ogre3D in your Project
Now that you have a basic C++ project running, the idea is to integrate the Ogre3D libraries inside the project.
Your project has two files:
*CMakeLists.txt (project configuration file)
*main.cpp (source code file)
Here is the current code for both:
CMakeLists.txt:
{CODE(wrap="1", ln=1, colors="c++")}project(tutorial1)
cmake_minimum_required(VERSION 2.8)
aux_source_directory(. SRC_LIST)
add_executable(${PROJECT_NAME} ${SRC_LIST}){CODE}
main.cpp:
{CODE(wrap="1", ln=1, colors="c++")}#include <iostream>

using namespace std;

int main()
{
    cout << "Hello World" << endl;
    return 0;
}{CODE}
Before changing anything in those files, let's reorganize the project files:
{CODE(wrap="1", colors="c++")}/opt/dev/ogreprojects/tutorial1 $> ls -l
total 40
-rw-r--r--  1 USER  wheel    329 Dec 10 21:10 CMakeLists.txt
drwxr-xr-x  9 USER  wheel    306 Dec 10 21:10 build
drwxr-xr-x  3 USER  wheel    102 Dec 10 21:09 main.cpp

/opt/dev/ogreprojects/tutorial1 $> mkdir src
/opt/dev/ogreprojects/tutorial1 $> mv main.cpp src/
{CODE}
Now, after performing some changes in the CMakeLists.txt file, this is how it looks like:
{REMARKSBOX(type="note",title="Note",close="n")}CMake is case insensitive{REMARKSBOX}
{CODE(wrap="1", ln=1, colors="c++")}PROJECT(tutorial1)

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -stdlib=libc++ -std=c++11")

MESSAGE(STATUS ${PROJECT_SOURCE_DIR}/src)

FILE(GLOB_RECURSE SRCS "${PROJECT_SOURCE_DIR}/src/*.cpp")
FILE(GLOB_RECURSE HDRS "${PROJECT_SOURCE_DIR}/src/*.h")

ADD_EXECUTABLE(${PROJECT_NAME} ${SRCS} ${HDRS}){CODE}
* Line 4: This helps to activate the C++11 support.
* Line 6: Printing the Project source dir path, only for informative purposes.
* Line 8-9: This is the CMake way to include the source code files in your project. From now on every source code should go inside the __src__ folder. CMake will search recursively inside this folder. 
* Line 11: This is the CMake way to say: "Create an executable using the project's source code...and name the executable file just like the project's name".
{REMARKSBOX(type="note",title="Note",close="n")}Whenever you perform a change in the CMakeLists.txt file, you should re-run the CMake command.{REMARKSBOX}
Run the CMake command, you should see something like this:
{CODE(wrap="1", colors="c++")}-- /opt/dev/ogreprojects/tutorial1
-- Configuring done
-- Generating done
-- Build files have been written to: /opt/dev/ogreprojects/tutorial1/build{CODE}
Build and run your project. You shouldn't get any errors.
!!!Binaries and App Bundles
In the terminal do:
{CODE(wrap="1", colors="c++")}$> cd /opt/dev/ogreprojects/tutorial1/build

16 -rw-r--r--   1 USER  wheel   5350 Dec 10 21:29 tutorial1.cbp{CODE}
Do you see the file called __tutorial1__?, that is the project's executable (or binary). In order to execute it, in the terminal run:
{CODE(wrap="1", colors="c++")}/opt/dev/ogreprojects/tutorial1/build $> ./tutorial1
Hello World{CODE}
The project has now an executable and you're able to run it. But things need to change a little bit in order to adapt in the Mac OS X's way of handling executables. In the Mac OS X platform you usually use what is called an __Application Bundle__ (a.k.a __app bundle__). An __app Bundle__ is a (special) directory that allows related resources such as an application's executable and its graphics to be grouped together, appearing as a single file to the user.
In order for the project to create an __app bundle__ instead of a plain binary, we need to change something in the CMakeLists.txt file. Change the line 11 in your CMakeLists.txt file for this one:
{CODE(wrap="1", colors="c++")}ADD_EXECUTABLE(${PROJECT_NAME} MACOSX_BUNDLE ${SRCS} ${HDRS}){CODE}
The only difference is the addition of the __MACOSX_BUNDLE__ flag to the __ADD_EXECUTABLE__ command. Now run the CMake command, then Build and Run. In your __build__ folder you should now see a new file called __tutorial1.app__:
{CODE(wrap="1", colors="c++")}/opt/dev/ogreprojects/tutorial1/build $> ls -l

16 -rw-r--r--   1 USER  wheel   5350 Dec 10 21:29 tutorial1.cbp{CODE}
If you try to run the app bundle just like we run the binary previously, you will get the following error:
{CODE(wrap="1", colors="c++")}/opt/dev/ogreprojects/tutorial1/build $> ./tutorial1.app
-bash: ./tutorial1.app/: is a directory{CODE}
If you want to run the binary from the terminal, you need to treat the app bundle as a directory (in fact __it's__ a directory):
{CODE(wrap="1", colors="c++")}/opt/dev/ogreprojects/tutorial1/build $> cd tutorial1.app/
/opt/dev/ogreprojects/tutorial1/build/tutorial1.app $> pwd

{CODE}
{REMARKSBOX(type="note",title="Note",close="n")}Don't worry about doing all these steps in order to run your binary every time. Wether it's a binary or an app bundle, QtCreator will take care of this and will launch your application when you select the __Run__ command from the __Build__ menu.{REMARKSBOX}
!!!Including Libraries in your Project
Currently this is the status of the main.cpp file:
{CODE(wrap="1", ln=1, colors="c++")}#include <iostream>

using namespace std;

int main()
{
    cout << "Hello World" << endl;
    return 0;
}{CODE}
Let's add a __Ogre::String__ in order to print something else:
{CODE(wrap="1", ln=1, colors="c++")}#include <iostream>

using namespace std;

int main()
{
    Ogre::String variable = "My first string using Ogre3D";
    cout << "Hello World: " << variable << endl;
    return 0;
}{CODE}
If you try to build the previous code, you will get an error:
{CODE(wrap="1", colors="c++")}/opt/dev/ogreprojects/tutorial1/src/main.cpp:9:5: error: use of undeclared identifier 'Ogre'
    Ogre::String variable = "My frist string using Ogre3D";
    ^
1 error generated.{CODE}
This means that the compiler is not able to find the __Ogre::String__ declaration in your code. In order to fix that we need to add the libraries of Ogre3D into the project.
This is the new CMakeLists.txt file:
{CODE(wrap="1", ln=1, colors="c++")}PROJECT(tutorial1)

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -stdlib=libc++ -std=c++11")

Changes:
*The following line was deleted because is no longer necessary:
{CODE(wrap="1", colors="c++")}MESSAGE(STATUS ${PROJECT_SOURCE_DIR}/src){CODE}
*Line 6: This line sets the location to the Ogre3D's include source code folder (this is the location where the compiler will find the definition of the __Ogre::String__).
*Line 7: Sets the location of the Ogre3D's libraries for the Linker (after the compilation process is done, the output is not yet a binary, it's what is called an __object file__. After the object file is generated by the compilation process, a special program called the __Linker__ "links" the libraries used by the source code to the compilation's output. After that process you end up with a binary file).
*Line 14: This line allows you to link a target (the project we are creating) to the given libraries (in this case the __ libOgreMainStatic.a__ library).  
If you want, you can polish a little bit more the CMakeLists.txt file:
{CODE(wrap="1", colors="c++")}PROJECT(tutorial1)

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -stdlib=libc++ -std=c++11")

SET(OGRE_BASE_FOLDER "/opt/dev/ogre3d-1.9.0/")

TARGET_LINK_LIBRARIES(

${OGRE_LIB_FOLDER}/libOgreMainStatic.a
){CODE}
Now go the main.cpp and add this line after the inclusion of the iostream library :
{CODE(wrap="1", colors="c++")}#include <OgreString.h>{CODE} 
You should have a main.cpp file like this:
{CODE(wrap="1", colors="c++")}#include <iostream>
#include <OgreString.h>

using namespace std;

bool start();

int main()
{
    Ogre::String variable = "My first string using Ogre3D";
    cout << "Hello World: " << variable << endl;
    return 0;
}{CODE}
When you included the previous line (__#include ‹OgreString.h›__), the QtCreator IDE should be able to find the definition of the __Ogre::String__. To validate if it's true, the __Ogre::string__ type should be colored in a purple tone:
{IMG(fileId="2229",rel="box[g]")}{IMG}  
Now run the __CMake__ command, then __Build__ and __Run__. Everything should be working fine:
{IMG(fileId="2230",rel="box[g]")}{IMG}
