Question

我刚刚将我的系统从Ubuntu 15.10升级到Ubuntu 16.04 LTS。现在，由于某种原因，我的C ++项目不再编译。正如你在编译日志中看到的那样，CLion一直在说它缺少了libx264.so.146：

/home/lorre851/CLion/bin/cmake/bin/cmake --build /home/lorre851/.CLion12/system/cmake/generated/ce7171e4/ce7171e4/Release --target main -- -j 8

大多数人似乎都在重新安装x264＆＃39;作为解决方案。但是，使用以下命令重新安装x264会导致在编译x264时出现相同的错误。

git clone git://git.videolan.org/x264
cd x264
./configure --enable-static
make

/usr/bin/ld: warning: libx264.so.146, needed by /usr/local/lib/libavcodec.so, not found (try using -rpath or -rpath-link)
/usr/local/lib/libavcodec.so: undefined reference to `x264_encoder_open_146'
collect2: error: ld returned 1 exit status
Makefile:202: recipe for target 'x264' failed
make: *** [x264] Error 1

有没有人知道如何解决这个问题？

好的，经过一天的尝试删除并重新编译liavcodec-dev库，没有结果，我决定格式化驱动器并从头开始重新安装Ubuntu。

现在一切正常。

编译C ++代码或x264本身时找不到libx264.so.146
