Radu,
I am building the main branch now - with the MATLAB module.
There seems to be a bug in
https://github.com/projectchrono/chrono/blob/2e6cae2d6578531d73f56d28893740ea009544ab/src/chrono_matlab/ChMatlabEngine.h#L85C1-L85C75
This leads to following error during make:
----------------------------------------------------------------
In file included from
/home/cralab/chrono/chrono/src/chrono_matlab/ChMatlabEngine.cpp:15:0:
/home/cralab/chrono/chrono/src/chrono_matlab/ChMatlabEngine.h:85:10: error:
extra qualification ‘chrono::ChMatlabEngine::’ on member ‘GetString’
[-fpermissive]
bool ChMatlabEngine::GetString(std::string& str, std::string varname);
^~~~~~~~~~~~~~
src/chrono_matlab/CMakeFiles/ChronoEngine_matlab.dir/build.make:75: recipe
for target
'src/chrono_matlab/CMakeFiles/ChronoEngine_matlab.dir/ChMatlabEngine.cpp.o'
failed
---------------------------------------------------------------
I removed the extra class declaration and it works. If you agree with this
fix, I can create an issue on github and create a pull request.
