默认安装的RHEL里面没有将GCC加入环境变量

[root@mail mpfr-2.2.0]# ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking for gcc... no
checking for cc... no
checking for cc... no
checking for cl... no
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.

 

解决办法：

[root@mail 3.4.3]# find / -name gcc

/usr/libexec/gcc

 

[root@mail 3.4.3]# set PATH=$PATH:/usr/libexec/gcc

 

[root@mail 3.4.3]# export PATH

搞定。
