Linux下安装tripwire-2.4.2.2-src.tar.bz2报错

Question

当我执行完./configure之后：checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
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 for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.

gcc版本信息为：
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)

楼主可以参考这个文章看看，大致意思就是：
1、gcc是不是安装好了，自己写一个hello的Demo编译一下就知道。
2、是不是环境变量被修改了，改回来，
sh export LIBS=
sh export CFLAGS=
