在 AIX 上本地安装 python3

我正在尝试在 AIX 7.1 上本地安装 python3 (3.5.2) 解释器，我使用它进行配置，运行正常

CC=gcc OPT="-O2" ./configure --enable-shared --prefix=$HOME/usr/local

但是在执行 make altinstall 时出现错误

/tmp/python3-src/Python-3.5.2 $ make altinstall prefix=$HOME/usr/local exec-prefix=$HOME/usr/local

Stop.

我检查了 /usr/include 中缺少的声明，看起来它们在那里。在进行本地安装时，我是否必须以某种方式手动指定这些包含的路径？

/usr/include $ grep -R "#define AT_EACCESS" .
./fcntl.h:#define AT_EACCESS            1       /* Check access using effective
/usr/include $ grep -R "#define AT_SYMLINK_NOFOLLOW" .
./fcntl.h:#define AT_SYMLINK_NOFOLLOW   1       /* Do not follow symbolic links */

编译时，

出现以下错误，

/Modules/posixmodule.c:2142:48: error: 'AT_SYMLINK_NOFOLLOW' undeclared (first use in this function)
                              follow_symlinks ? 0 : AT_SYMLINK_NOFOLLOW);

posixmodule.c 2142行如下所示，这里使用了 fstatat 方法；

#ifdef HAVE_FSTATAT
    if ((dir_fd != DEFAULT_DIR_FD) || !follow_symlinks)
        result = fstatat(dir_fd, path->narrow, &st,
                         follow_symlinks ? 0 : AT_SYMLINK_NOFOLLOW);
    else
#endif

所以此修复；应该应用来解决该问题。
