我正在尝试使用swig运行Python来执行C / C ++。我正在运行教程here，'构建一个python模块'。当我打电话时
gcc -c example.c example_wrap.c -I /my_correct_path/python2.5
我收到错误：
my_correct_path/python2.5/pyport.h:761:2: error: #error "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)."
example_wrap.c: In function 'SWIG_Python_ConvertFunctionPtr':
example_wrap.c:2034: warning: initialization discards qualifiers from pointer target type
example_wrap.c: In function 'SWIG_Python_FixMethods':
example_wrap.c:3232: warning: initialization discards qualifiers from pointer target type
它确实创建了一个example.o文件，但它不起作用。我在使用python2.5而不是2.1，例如，这是一个问题吗？错误（其他一切只是一个'警告'）说错误的平台。这是一台64位的机器;这是一个问题吗？我的gcc配置错误了吗？我如何通过这个？
更新：我仍然遇到问题。我如何实际实现这个“修复”？

我发现这个线程正在为64位centos上安装32位python的python readline时出现相同“LONGBIT”错误的答案。该链接没有直接的答案，所以我不得不进一步谷歌答案（对于经验丰富的Linux用户/开发者来说可能是直截了当的）。为了将来参考，解决方案是在CFLAGS环境变量中使用“-m32”强制32位。

然后我尝试使用CFLAGS = -m32：

最新的错误是由于没有32位的glibc-devel包（感谢this thread）。我还必须安装ncurses-devel.i386然后easy_install经过并且ipython认出了它。直到我为了ipython而工作，我的生活才被毁了。

我在尝试安装Python软件包时遇到了同样的错误，但修复了它 “LONG_BIT”错误是：
$ easy_install astropy
/my_path/epd/epd-7.3-2-rh5-x86/include/python2.7/pyport.h:849:2:
error: #error "LONG_BIT definition appears wrong for platform
(bad gcc/glibc config?)." error: Setup script exited with error:
command 'gcc' failed with exit status 1
正如你所建议的那样，Alex，我必须安装正确版本的Python的epd才能满足我的机器要求和我想要安装的软件包的要求。有并行版本的Python运行，我认为这是混乱和错误的来源。转到Enthought's Repository（单击“登录存储库” - ＆gt;安装程序）并安装正确的版本。
通过删除旧的Python版本，确保清理（或询问知道他们正在做什么的人为您做这件事）。然后当然更改.cshrc路径以指向新版本并正确地获取文件。我这样做后没有问题。
我意识到4年前就提出了这个问题！

在尝试从源代码安装libxml2时，我实际上发现了这个线程两次，相隔几年。库的configure脚本实际上有一个--without-python选项，我使用它而不是尝试修复错误。
