我正在尝试在RHEL 5.7机器上构建
Python3,我成功地构建了Python 3.2.2,其中：
# Install required build dependencies yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel # Fetch and extract source. Please refer to http://www.python.org/download/releases # to ensure the latest source is used. wget http://www.python.org/ftp/python/3.2/Python-3.2.tar.bz2 tar -xjf Python-3.2.tar.bz2 cd Python-3.2 # Configure the build with a prefix (install dir) of /opt/python3,compile,and install. ./configure --prefix=/opt/python3 make
但我在Python 3.2.3中失败了(？)：
Failed to build these modules: _posixsubprocess
这是一个应该打扰我的问题吗？我该如何构建它？
我找到了this patch,但它没有包含在我从网站上获得的Python 3.2.3源代码中……
这是stderr的输出：

解决方法
好的……我在这里回答,不要回答这个问题.
我重新下载了Python-3.2.3源并检查它们.他们确实不包括那个补丁.
我重新应用了补丁并在CentOS-5.7和RedHat-5.7上测试了该建筑物.我设法编译没有错误.
所以,我想关键是要正确应用补丁.
我的失败构建在Modules / _posixsubprocess中：

第205行应该已被删除…
