I’m trying to build a static libtorch in a brand new conda environment, following the instruction in the README.md in the repository.
It builds during a while, but up to a point I have a bunch of errors:
onnx.lib(defs.cc.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary' : value 'MT_StaticRelease
' doesn't match value 'MD_DynamicRelease' in core.obj
onnx.lib(old.cc.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary' : value 'MT_StaticRelease'
doesn't match value 'MD_DynamicRelease' in core.obj
etc… it goes like this during a while, then a bunch of already defined symbols:
msvcprt.lib(MSVCP140.dll) : error LNK2005: "protected: __cdecl std::basic_streambuf<char,struct std::char_trait

The output is really similar to this message in that issue:
The Runtime Library errors really puzzle me, am I setting some flags wrong? I am not setting any flag that has anything to do with /MT or /MD though.
