CRRCSim is an RC model-plane simulator (http://sourceforge.net/projects/crrcsim/) for Linux that allows you to fly planes with not only your mouse/keyboard/joystick, but also with your RC plane transmitter. See my next post for how to get your RC plane transmitter talking to your Mac and CRRCSim. Now compiling and getting CRRCSim to run on a Mac is a bit tricky so let me walk you through the steps.
Step 1: You will need to install XCode if you have not already
Step 2: You will need to install MacPorts and then some Linux libraries from MacPorts that are not included with MacOSX by default
> sudo port install plib
> sudo port install jpeg
> sudo port install portaudio
> sudo port install libsdl
Step 3: Download the source code for CRRCSim from sourceforge.net and unpack it:
> cd $HOME/Downloads
> tar xzf crrcsim-0.9.12.tar.gz
Step4: You will need to edit src/mod_misc/filesystools.cpp to make the search path work right for MacOSX. Here is a diff file that will allow CRRCSim to be launched via the Finder or via the command prompt.

> if (dirname != "")
> {

> s2.append(dirname);

> pathlist.push_back(s2);
Step 5: Configure, Compile, and Install CRRCSim
> cd $HOME/Downloads/crrcsim-0.9.12
> ./configure CPPFLAGS="-I/opt/local/include -DAPIENTRY=" LDFLAGS="-L/opt/local/lib -lintl -framework OpenGL" --prefix=$HOME/crrcsim.app
> make
> make install
Step 6: Fix up the directories to be MacOSX like
> cd $HOME/crrcsim.app
> mkdir Contents
> cd Contents
> mkdir Frameworks PlugIns Resources SharedFrameworks
> mv ../bin MacOS
> mv ../share/crrcsim/* Resources/
> mv ../share Resources/
> rmdir Resources/share/crrcsim/
> mv Resources/share/doc/crrcsim/* Resources/share/doc/
> rmdir Resources/share/doc/crrcsim/
Step 7: Add the Icon file from the source tree. NOTE: if you download the tar.gz tar ball then you will not have the MacOSX icn file. You need to get this from the source tree itself. It is called: crrcsim.icns and you need to put it in $HOME/crrcsim.app/Contents/Resources/
Step 8: Create the Info.plist and PkgInfo files in $HOME/crrcsim/Contents/ see the following web sites for more details. I will include samples below. (https://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPRuntimeConfig/Articles/ConfigFiles.html) and (https://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPRuntimeConfig/Articles/ConfigApplications.html)
Step 9: Copy the crrcsim.app directory over to your /Applications/ directory and have fun playing the RC plane simulator. I will post more details about making a disk image at a later time.
Thanks a lot for posting this. It really helped me out a lot!

Thank you for your instructions - this has helped me to successfully build CRRCSim 0.9.12 on Mac OS 10.9 (Mavericks). Could you provide some more instructions and hints for creating a disk image?
ReplyDeleteFrom the little research I have been doing, I believe the best approach would be to copy all dynamic libraries into the .app bundle's structure. This necessitates to rewrite the linked paths in both the binary and the libraries, but this nevertheless seems to be a popular approach, compare this stackoverflow question http://stackoverflow.com/questions/1596945/building-osx-app-bundle. Which is the approach you've been taking? Which tools and methods have you been using?
