First of all, apologies for cross-posting but this problem cuts across a few specialties. Let me explain the background of the problem.
The 3d application Maya (from AutoDesk) has a scripting interface that has several thousand commands one of which is called system. The command system allows an external binary/program to be launched via Maya. Unfortunately, this command refuses to run a simulator (written in C++ by one of our students). The simulator program works well on its own as a standalone app but cannot be launched by Maya via the system command. In order to figure out why, I attached strace to Maya and tried running simulator again, and got the following error message: clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID| SIGCHLD, child_tidptr=0xaf70e778) = 28741 /home/timmy/project/bin/simulator: /opt/autodesk/maya/lib/libstdc++.so. 6: version `GLIBCXX_3.4.9' not found (required by /home/timmy/project/ bin/simulator) Clearly, Maya and simulator are linked to different versions of the C+ + shared object library. (Warning OS talk ahead) Here's what I think caused the error: 1. as Maya is the parent process it loaded its preferred version of libstdc++. 2. subsequently, the OS, while execing simulator, did not (is not programmed to) check if version of the libstdc++ library inherited from Maya is the same as the version of the libstdc++ library required by simulator, and therefore assumed that the requisite library was loaded. Theory aside, how can I solve this problem (i.e. launch the simulator from Maya) bearing in mind that the user does not have admin privileges to the machine. One of the options I've considered is compiling the simulator with the same version of the g++ as Maya. I'd like to know if there are other options.
