来自python的gcc编译错误

Question

我知道gcc上有很多线程，特别是“commandgcc failedwithexitstatus1”，我已经查看了所有线程，但仍然无法修复这个问题。我只将gcc或mingw32用于与python相关的任务，比如使用Cython或其他可能涉及编译的包。然而，它似乎从来没有起作用。

我有一台装有Windows7家庭版的电脑。我用mingw32在上面安装了cygwin，还安装了visualstudio11beta，我很高兴卸载/重新安装任何东西来让它工作。

Cython编译总是失败

error: command 'gcc' failed with exit status 1

但是，即使尝试使用pip安装许多python包也失败了，并出现了类似的错误。例如，我试图安装一个名为“xhtml2pdf”的包。在命令提示符中运行“pip install xhtml2pdf”之后，我得到以下错误：

copying src\reportlab\lib\hyphen.mashed -> build\lib.win32-2.7\reportlab\lib

running build_ext

building '_rl_accel' extension

C:\mingw\bin\gcc.exe -mno-cygwin -mdll -O -Wall -IC:\Python27\include -IC:\Pytho
n27\PC -c "C:\Users\JJ\Documents\Coding Fun\build\reportlab\src\rl_addons\rl_acc
el\_rl_accel.c" -o "c:\users\jj\documents\coding fun\build\reportlab\src\rl_addo
ns\rl_accel\_rl_accel.o"

cc1.exe: error: unrecognized command line option '-mno-cygwin'

error: command 'gcc' failed with exit status 1

从cygwin运行相同的命令会产生不同的错误：

一般来说，我对编译很陌生，只使用过解释性语言，所以我很沮丧地无法自己解决这个问题。如果您能帮忙安装这个软件包，我们将不胜感激。

编辑：我以前遵循过一些建议，比如尝试删除distutils中对“-mno cygwin”的所有引用，并创建一个distutils.cfg文件，但没有效果。

更新：在重新安装cygwin并将gcc和g++的安装降级到v3之后，我得到了另一个不同的错误：

Answer 1

我在cygwin中遇到了这个问题，直到我意识到还需要安装gcc-g++包。现在我已经安装了gcc核心和gcc-g++了，pip install pandas工作起来就像一个符咒。

Answer 2

所以，过了一会儿，我偶然发现了一个迄今为止对我有用的帖子。

http://www.develer.com/oss/GccWinBinaries

这个站点提供了一个非官方的MinGW GCC二进制文件（MinGW不支持/不支持），旨在与Python完美集成，直至自动更新路径。我安装了它，bam，pip install cython才开始工作。

希望这能帮助你们解决gcc的问题。

Answer 3

我刚刚回答了同样的问题：为什么dllwrap会在pip中给出这个错误？

_foo.exp: file not recognized: File format not recognized

简而言之：检查你的路径。MinGW\bin需要在它的开始附近。

长答案：见python pip package install fails , dllwrap error after 'fixing': "unable to find vcvarsall.bat"
