Currently I am trying to run my Simulink model, built with Matlab 2019b, on a server of my university, which runs on Linux CentOS 7.3.1611. If I run the model in either 'normal', or 'accelerator' mode it is successful. However, if I try to run the model in 'rapid accelerator mode' the compiler returns an error during building. The errors all contain the element of not finding the standard library:
undefined reference to `std::__cxx11::basic_string<char, std::char_traits<char>
I have searched on MATLAB Answers and stackoverflow for solutions, but none have worked for me so far. I have also asked the IT service of my university for help but they could not help me out.
One of the solutions hinted towards the compiler not being able to find the correct libraries and that the library path should be added/updated here on stack overflow. However, if I print the Library path in matlab then it seems allright: Library path:
<matlab_root>/cefclient/sys/os/glnxa64:<matlab_root>/sys/opengl/lib/glnxa64:<matlab_root>/sys/os/glnxa64:<matlab_root>/bin/glnxa64:<matlab_root>/extern/lib/glnxa64:<matlab_root>/runtime/glnxa64:<matlab_root>/sys/java/jre/glnxa64/jre/lib/amd64/native_threads:
<matlab_root>/sys/java/jre/glnxa64/jre/lib/amd64/server:<compiler_root>/root/usr/lib64:<compiler_root>/root/usr/lib:<compiler_root>/root/usr/lib64/dyninst
Another problem could be the compiler. At first I used a gcc 8.x compiler, but later found out that a 6.3 version is required, so that is what I am using now
Lastly I found a that a problem could be that "(...) it probably indicates that you are trying to link together object files that were compiled with different values for the _GLIBCXX_USE_CXX11_ABI macro." (from stack overflow) The last option seems the most likely to me, however, I have not been able to solve this. I tried for instance:
set_param(model,'AccelMakeCommand','make_rtw CPP_OPTS="-D_GLIBCXX_USE_CXX11_ABI=0"')
and
set_param(model,'MakeCommand','make_rtw CPP_OPTS="-D_GLIBCXX_USE_CXX11_ABI=0"')
However, this did not help.
If anyone has a tip that could help me out, that would be great. I have added parts of the console output and the error message were it goes wrong down below for extra info.
Kind regards, Nathan
