I am trying to run this test file test_lfmm3dtria_direct.m from this 3D Boundary Element Method project https://github.com/mjcarley/bem3d/tree/master/fmmlib3d-1.2/matlab and i get the following error, even though there are some "fmm3d_r2012a.mexa64" , "fmm3d_r2012a.mexw32" files in the folder
Unrecognized function or variable 'fmm3d_r2012a'.
Error in lfmm3dtria (line 133)

ifpot, pot, iffld, fld, ntarget, target, ifpottarg, pottarg, iffldtarg, fldtarg, 1, 1, 1, 3, nsource, 3, nsource, 1, 1, 3, nsource, 1, 1, 1, 1, 1);

[U]=lfmm3dtria(iprec,ntri,triangles,trianorm,source,ifcharge,charge,ifdipole,dipstr,dipvec,ifpot,iffld,ntarget,target,ifpottarg,iffldtarg);
when i tried to rebuild them from the "fmm3d_r2012a.c" source file I got this.
mex fmm3d_r2012a.c
Building with 'MinGW64 Compiler (C)'.

Hi,
I understand that you are facing an issue while trying to use the mex command. The error ‘collect2.exe: error: Id returned 1 exit status’ usually occurs when winsock library is missing.
Please follow the troubleshooting steps provided in the MATLAB answer below:

Hope this helps!
