I have tried recompiling zlib from the sources, however I am still getting errors when I try to compiling SOFA. I followed this guide for compiling zlib, and that seemed to be successful. I end up with a file named “zlibwapi.dll”, however the zlib readme says that I may rename the file to “zlib.dll”.

I am going to keep trying.

Here is the new set of errors I am encountering. Hopefully this should help diagnose the error:

Thanks Guillaume,

That did seem to fix the error I was having. However, I am now getting another set of errors. The main cause of this seems to be a conflict with MSVCRT. This prevents SofaLoader_d.dll, SofaExporter_d.dll, and SofaMiscTopology_d.dll from being built. This is from building the debug version.

Unlike before, most of the .dlls build successfully and the runSofa_d.exe is made. However, runSofa_d.exe creates an error because SofaLoader_d.dll is missing.

I’ll try some of the suggestions I found online for dealing with LNK4098. In the meantime, here are the error messages I am getting.
