Did you mean to exclude NFS? I will have to check that, can't remember the last time I tried to build it without nfs.

If you are getting that message then it is trying to run AVX-ECM. Does your cpu support AVX-512? If not, then you need to alter the compiler flags in the build configuration.

This is strange to hear. For me, wsl is far superior to the pre-built windows version, which was made with visual studio. SIQS, ECM, and NFS should all run faster in wsl. Building with mingw is...

Using mingw64 (I assume with msys2/ucrt64), build msieve with WIN=1 WIN64=1 on the make command line, e.g., make all NO_ZLIB=1 WIN=1 WIN64=1

This tells the build to omit -ldl, among other things.
