GCC安装问题

knill

我在安装gcc-3.4.3 时出现下面的问题，请问应该怎么解决啊？

loading cache ./config.cache
checking host system type... i386-redhat-linux-gnu
checking target system type... i386-redhat-linux-gnu
checking build system type... i386-redhat-linux-gnu
checking for a BSD compatible install... /usr/bin/install -c
*** This configuration is not supported in the following subdirectories:
     target-libf2c target-libobjc
    (Any other directories should still work fine.)
../gcc-3.4.3/configure: line 2332: cc: command not found
*** The command 'cc -o conftest -g   conftest.c' failed.
*** You must set the environment variable CC to a working compiler.
