window下使用Mingw编译python扩展库ujson

放一个我编译好的http://download.csdn.net/detail/toontong/4372898

关于ujson，请看：http://simple-is-better.com/news/458

安装MinGW， 我使用mingw-get-inst-20120426.exe安装，网络安装，有时没法安装完整，下载总不稳定。

过了两天跑才下载到gcc.exe。

python版本为2.6.8, gcc.版本为version 4.6.2 (GCC)

可以运行

python setup.py build -c mingw32

第一次输出错误：

cc1.exe: error: unrecognized command line option '-mno-cygwin'
error: command 'gcc' failed with exit status 1

查了，原来是gcc的4.6的版本后去除了参数'-mno-cygwin'项，此参数项在文件：

C:\Python26\Lib\distutils\cygwinccompiler.py

中，直接修改这个文件，把几个 '-mno-cygwin'全删除。再运行：

python setup.py build -c mingw32

第二次输出错

注意红色那句，类型重复定义，好吧，直接打开ultrajson.h 第83，注释//typedef unsigned __int32 uint32_t;

再编译 python setup.py build -c mingw32 

C:\MinGW\bin\gcc.exe -shared -s build\temp.win32-2.6\Release\.\python\ujson.o bu
ild\temp.win32-2.6\Release\.\python\objtojson.o build\temp.win32-2.6\Release\.\p

n.def -LC:\Python26\libs -LC:\Python26\PCbuild -lpython26 -lmsvcr90 -o build\lib
.win32-2.6\ujson.pyd

 成功了

添加一个setup.cfg文件,内容为：

[build]
compiler = mingw32

再运行

python setup.py bdist_wininst

得到 window下的安装文件：

ujson-1.18.win32-py2.6.exe
