Linux下编译ffmpeg报错gcc is unable to create an executable file C compiler test failed.

代码报错信息：

[root@bjs1 ffmpeg-3.2.2]# ./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
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file “config.log” produced by configure as this will help
solve the problem.

原因:linux系统没有安装gcc编译器

yum install gcc
