为 Python 设置 pjsip

Question

我正在尝试安装 pjsip 的 Python 绑定，但运行遇到构建错误，我认为这是环境问题，但我无法找出问题所在。

我能够毫无问题地构建 pjsip，但是运行在尝试构建 python 绑定时遇到了问题 -- 我从 ld 收到一个错误值的错误静态库的数量。

有什么想法吗？

Answer 1

我能够在旧邮件列表条目 (http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2008-August/004456.html) 中找到答案。

设置 CFLAGS=-fPIC 并重建 PJSIP 库（make clean && ./configure && make dep && make），然后按照制作 Python 库的说明进行操作。
