Hi,

I'm trying to compile some code under Win with MSVC but I obtain:

C:\HiGHS\include\highs\util/HighsHash.h(105,46): error C3861: '__builtin_clzll': identifier not found
C:\HiGHS\include\highs\util/HighsHash.h(107,46): error C3861: '__builtin_clz': identifier not found
C:\HiGHS\include\highs\util/HighsHash.h(109,42): error C3861: '__builtin_popcountll': identifier not found

I found something like this online here.

Can anyone fix this problem?

Thx.

this error was due to building with -G "Mysys Makefile" and after using it in MSVC context
