When trying to install a certain Python geophysical toolkit, I get this error:
LINK : fatal error LNK1181: cannot open input file 'm.lib'
I believe it is due to my use of the MSVC's buildtools. In their setup.py I found:
setup(…, ext_modules=[ Extension(…, […], libraries=['m'], … ])
What do I need to change in this setup.py—and related files?—to make this work. IIRC there is a library other than m which I am to use.
On Windows, the standard math functions are handled by MSVCR:
>>> from ctypes.util import find_library
>>> find_library('m')
'msvcr90.dll'
I don't have MSVC installed to test, but you just need to link against the runtime. Try removing 'm'.
