我正在尝试在 RHEL 5.7 机器上构建 Python3，我成功构建了 Python 3.2.2，使用：
# 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
但是我使用 Python 3.2.3 失败了（？）：
Failed to build these modules:
_posixsubprocess
这个问题会困扰我吗？我该如何构建它？我发现此补丁，但它不包含在我从网站获得的 Python 3.2.3 源中……
以下是 stderr 的输出：

答案1
好的……我在这里回答，不想留下问题悬而未决。我重新下载了 Python-3.2.3 源代码并检查了它们。它们确实不包含该补丁。
我重新应用了补丁并在 CentOS-5.7 和 RedHat-5.7 上测试了构建。我成功编译，没有出现任何错误。
所以，我猜关键是正确应用补丁。我失败的构建在 Modules/_posixsubprocess 中：
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，应该被删除...
