The software is developed on OSX. To compile the MEX library execute CompileLib.m on the directory matlab. To compile the c++ lib (to be used in c++) there is a makefile (that work on linux and OSX) and a CMakeLists.txt to be used with cmake on all the platforms.

Has anyone compiled this with macOS on a macbookair? Can the instructions be posted here please, thanks.

Thank you for sharing and following people's requests. Definitely a good practice! I hope to benefit from this work for my research.

I found a solution by changing line 398 in to include parentheses :

return (std::max)(d1,(std::max)(d2,d3)) ;

(solution found here:

if you are compiling on windows with visual studio compiler probably the error is due to some version of the compiler which defined max and min as macros. I added a workaround for that in the last version of the library.

It is correct, in the latest version I added the header inclusion. The error is due to that fact I develop mainly on OSX which include headers for STL in a slight different way.

Hi,I tried to compile your Lib. There is an error in Triangle2D I think you forgot to include the Header <algorithm>. After I fixed that i was able to compile it in Matlab.
