Error when using mex'd "apply_ambient_occlusion" #95

Closed taiya closed 4 years ago

taiya commented 4 years ago

Compiling of mex folder was "ok" (there were two C++ files missing, but build went through by just touch missingfile.cpp). However, when calling from matlab (see error below).

I wonder whether there is an unstated assumption about the exact compiler one is supposed to use? I remember MATLAB was brittle like that...

Depending on multiple library versions does not sound like a good idea. This seems to be because I am using R2017b, which expects an older version of cgal/boost, but my OS has new'ish boost

Yes. this looks like a std-library/boost mismatch. Might try to convince the mex compilation to find the matlab version of boost. Thought this can be tricky. For now, I'm only going to track down compilation errors for 2019+ (the versions I have access to).

If you find a solution, please do post it for others.

Agreed, this is because I only have access to MATLAB 2017. Good to close it, but I thought to report if others are running into similar problems ;)
