LNK1181:无法打开输入文件“m.lib"
问题描述
在尝试安装某个 Python 地球物理工具包时,我收到此错误:
When trying to install a certain Python geophysical toolkit, I get this error:
LINK : 致命错误 LNK1181: 无法打开输入文件 'm.lib'
LINK : fatal error LNK1181: cannot open input file 'm.lib'
我相信这是因为我使用了 MSVC 的构建工具.在他们的 setup.py
我发现:
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'], … ])
我需要在此 setup.py
和相关文件中进行哪些更改? - 才能使其正常工作.IIRC 有一个除 m
之外的库供我使用.
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.
解决方案
在 Windows 上,标准数学函数由 MSVCR 处理:
On Windows, the standard math functions are handled by MSVCR:
>>> from ctypes.util import find_library
>>> find_library('m')
'msvcr90.dll'
我没有安装 MSVC 来测试,但您只需要链接到运行时.尝试删除 'm'
.
I don't have MSVC installed to test, but you just need to link against the runtime. Try removing 'm'
.
