I am the beginner for ROS and trying to run the AspectC++, but now I am stuck with the compilation issue. Since the AspectC++ is using ac++ or ag++, while the ROS is using c++ compiler, I am wondering if we can change the compiler of ROS to some other else? And how? Please help and Thanks in advance
CMake honors the CC and CXX environment variable so you can use whatever compiler you prefer by setting these variables. For instance, I use ccache for all my ROS compilation without any trouble.
export CC=/path/to/my/c/compiler
export CXX=/path/to/my/c++/compiler
rosmake
You can then double check which compiler has been used by running:
grep COMPILER CMakeCache.txt
...in any ROS build directory. CMAKE_CXX_COMPILER should be your custom C++ compiler.
Unless you recompile ROS from scratch, you will have to make sure that the ABI are compatible (i.e. that you can link a g++ library against an aspectc++ one).
Be aware that porting the code so that it is compatible with a new compiler is a lot of work. Do not do it unless you are already a C++ experienced programmer and ready to spend a couple of months on this.
Didn't you already ask this question??? Why can't you just compile ROS with g++ and write your nodes with AspectC++? If AspectC++ doesn't support this, then it would probably take a lot of work to fix ROS.
I have never heard of AspectC++ before, so I could be wrong. Please take a look at the REPs to help understand what ROS is ... specifically REP-3 Target Platforms and REP-9 ABI Compatibility to see if AspectC++ violates those. Some of the other ones might be useful to read too. Good luck!
