为Python设置pjsip [英] Setup pjsip for Python
问题描述
我正在尝试安装pjsip的Python绑定，但是遇到了一个编译错误，我认为这是环境问题，但无法找出问题所在.
I'm trying to install pjsip's Python binding but am running into a build error that I feel is environmental but am just not able to figure out what's wrong.
我能够毫无问题地构建pjsip，但是在尝试构建python绑定时遇到了一个问题-我从ld得到一个错误，原因是其中一个静态库的值错误.
I'm able to build pjsip without issue but run into a problem when trying to build the python bindings -- I'm getting an error from ld about a bad value in one of the static libraries.
有什么想法吗?

推荐答案
I was able to find an answer in an old mailing list entry (http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2008-August/004456.html).
设置CFLAGS = -fPIC并重建PJSIP库(make clean& ./configure&& make dep& make)，然后按照说明制作Python库.
Set CFLAGS=-fPIC and rebuild the PJSIP library (make clean && ./configure && make dep && make), then follow the directions for making the Python library.
