编译问题

x265在make install时报错

$ make install
common/CMakeFiles/common.dir/compiler_depend.make:4: *** 多个目标匹配。 停止。
make[1]: *** [CMakeFiles/Makefile2:253：common/CMakeFiles/common.dir/all] 错误 2
make: *** [Makefile:136：all] 错误 2

使用 cmake –install . 替换 make install

ffmpeg在configure时报错

ERROR: x265 not found using pkg-config

需要修改x265.pc文件，把-lstdc++放在Libs下
