.sodu /configure--prefix=/usr 通过了，sudo make有错误，有知道是什么问题么？
libmediastreamer的库都装了遍了，deb的安装文件也用过！就是有错误，linphone也太难装了不，卡在这个位置了，谁帮帮忙阿！！

解决方法：1. vi mediastreamer/tests/Makefile, 在LIBS=那里增加-lavutil
2. vi mediastreamer/src/Makefile, 在LIBS=那里增加-lavutil
3. 若还不行，先make clean一下，再make

虽然过了一个月才有人回复，但是也谢谢了

可否将linphone的安装过程详细的介绍一下

谢谢
