Env: python 3.7.3
I have installed autowrap and cython manually with pip before I install py-go-icp

Console log out this:

@lyldev,

Looks like the library compiles fine. Rather this is an annoying but simple issue of text encoding error due to readme file in setup.py file. Perhaps you can download the repository and remove the long description field in setup.py and then try python setup.py build_ext. This should compile successfully after which you can do python setup.py install. Meanwhile I will try and fix the issue so it works over pip without issues. Let me know how it goes.

@aalavandhaann Thanks for your review. I will try this solution.

Answer 3 · 2020-06-05T12:32:03.000Z

@aalavandhaann
I cloned this repo and remove the long_description field in setup.py, but when I try python setup.py build_ext, this error occurred：

d:\codes\vscode\go-icp_cython\src\matrix.hpp(33): error C2371: “int8_t”: 重定义；不同的基类型（Redefinition; different base types）

modified setup.py (only remove long_description field) :

setup(cmdclass={'build_ext':build_ext},
      name="py_goicp",
      version="%d.%d.%d" % VERSION,
      ext_modules = [ext],
      install_requires=['autowrap>=0.22'],

      long_description_content_type='text/markdown',
    #   long_description=open('README.md').read(),
      zip_safe=False,
     )

Complete console output:

Okay. I will try on my machine on windows 10(believe it's the one you are using) and will let you know. Regards, #0K

Yes, Win10 64bit.

Looks like msvc is complaining about redefinition of int8_t and other types followed. You should be able to solve this using the given solution (ugly but works). The difference is tiny but you should be able to sucessfully do a python setup.py build_ext.

Do the following in the files

setup.py

change line number 66 to
long_description=open('README.md', encoding='utf-8').read(),

matrix.hpp

line numbers 33-36

change from

typedef __int8            int8_t;
typedef __int16           int16_t;
typedef __int32           int32_t;
typedef  __int64           int64_t;

TO

typedef signed __int8            int8_t;
typedef signed __int16           int16_t;
typedef signed __int32           int32_t;
typedef signed __int64           int64_t;

The above changes in the two files should fix the issues. Let me know if you still have any trouble.
