我正在尝试在ubuntu下编译简单的PjSIP程序。我收到错误
/usr/bin/ld: cannot find -lpjsua-i686-pc-linux-gnu
这是什么意思?
这是输出: -

我刚注意到构建PjSIP
时出错make [2]:输入目录

当我试图在/home/mypc/pjproject-1.4.5/pjnath/build
,$(PJDIR)/build.mak
和$(PJDIR)/build/common.mak
中出现make文件时出现-Werror时,没有人知道它可能在哪里?
答案 0 :(得分:3)
似乎pj *无法构建必要的库 - 要进行简单的修复,请尝试在/home/mypc/pjproject-1.4.5/build.mak
中找到-Werror
添加到$(APP_CFLAGS)
并删除它的行( -Werror
,如果添加了其他标志,则不是整行:)。
或者在src/pjnath/stun_session.c
的第230行应用gcc建议的修复。
修改强>
请注意,您没有找到-Werror
。你能粘贴stun_session.c的230行还是make文件?
源行是首选。
