问题如下

$ ./configure --enable-shared  --prefix=/usr/local/ffmpeg
gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

点开/ffbuild/config.log，查看出错信息，出错信息为如下所示

/usr/bin/ld: cannot find crtbegin.o: No such file or directory 
/usr/bin/ld: cannot find -lgcc 
/usr/bin/ld: cannot find -lgcc_s

直接原因：找不到crtbegin文件所致，间接原因：gcc未配置好（猜得），
故在/usr下查找crtbegin

$ sudo find /usr/ -name crtbegin*
/usr/lib/gcc/x86_64-linux-gnu/7/crtbeginS.o
/usr/lib/gcc/x86_64-linux-gnu/7/crtbeginT.o
/usr/lib/gcc/x86_64-linux-gnu/7/crtbegin.o
/usr/lib/gcc/x86_64-linux-gnu/5/crtbeginS.o
/usr/lib/gcc/x86_64-linux-gnu/5/crtbeginT.o
/usr/lib/gcc/x86_64-linux-gnu/5/crtbegin.o

可以看出usr文件内含有该文件，只要增加一个路径即可
我按装了两个版本的gcc，一个为gcc-7.4，一个为gcc-5.4.0，目前正在使用的版本为5.4，所以路径应该为/usr/lib/gcc/x86_64-linux-gnu/5/crtbegin.o
在ffmpeg目录下，打开终端

LIBRARY_PATH=/usr/lib/gcc/x86_64-linux-gnu/5:$LIBRARY_PATH
export LIBRARY_PATH

再./configure后即可成功
注：configure成功后，make，make install时可能会再出现如下问题：

/usr/bin/ld: cannot find crtbeginS.o: No such file or directory
collect2: error: ld returned 1 exit status

解决方案就是，打开bashrc，

LIBRARY_PATH=/usr/lib/gcc/x86_64-linux-gnu/5:$LIBRARY_PATH
export LIBRARY_PATH
```
把上面的路径再复制粘帖进去，重新make instal，大功告成！
