why

Sibras commented 5 years ago

Check all your project settings correctly as your clearly compiling in 32bit

E:\work\bubi\project\test_atl_bn128\zsl\build\win32\dbin\LibZsl.exe

note the win32 above.

However this is not the correct location for such user errors as only issues with smp libgmp itself should be listed. Try stack overflow for help with using Visual studio correctly.
