我正在试图在RHEL 5.7机器上构buildPython3，我成功地构build了Python 3.2.2，其中包含：
# 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 但是我在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？ 我如何构build它？ 我发现这个补丁 ，但它不包括在源Python 3.2.3我从网站获得…
这是来自stderr的输出：

好的…我在这里回答，不要不回答这个问题。 我重新下载了Python-3.2.3源代码并检查了它们。 他们确实不包括那个补丁。
我重新应用了这个补丁，并在CentOS-5.7和RedHat-5.7上testing了这个build筑。 我设法没有错误编译。
所以，我想关键是正确应用补丁。 我的失败的生成在模块/ _posixsubprocess：
199 static void 200 _close_open_fd_range_safe(int start_fd, int end_fd, PyObject* py_fds_to_keep) 201 { 202 int fd_dir_fd; 203 if (start_fd >= end_fd) 204 return; 205 fd_dir_fd = open(FD_DIR, O_RDONLY | O_CLOEXEC, 0); 206 #ifdef O_CLOEXEC 207 fd_dir_fd = open(FD_DIR, O_RDONLY | O_CLOEXEC, 0); 208 #else 209 fd_dir_fd = open(FD_DIR, O_RDONLY, 0); 210 #ifdef FD_CLOEXEC
第205行，应该已经删除…
