编译ffmpeg的时候报错 ERROR: libfdk_aac not found

参考

http://www.mirrorservice.org/sites/www.linuxfromscratch.org/blfs/view/systemd/multimedia/fdk-aac.html

进行编译居然报错：

  CXX      libAACdec/src/FDK_delay.lo
./libtool: line 1762: g++: command not found
make: *** [Makefile:1752: libAACdec/src/FDK_delay.lo] Error 1

这个错找了很久

./libtool: line 1762: g++: command not found

每篇文章都没说在点子上，最后试了这条命令

sudo apt-get install build-essential

ubuntu下g++报错 g++:command not found解决办法_qq_32039433的博客-CSDN博客

终于解决了我的问题。在执行编译命令

./configure --prefix=/usr --disable-static && make

make install

看样子是libfdk_aac 编译是成功了，再次编译ffmpeg ，又报了其他错误，继续踩坑中….

----------------------------------------------------------------------
Libraries have been installed in:
   /usr/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
