我遇到与c compiler cannot create executable on mac类似的问题。看起来该线程的最终建议是卸载gcc。没有卸载gcc有没有办法解决这个问题？我似乎记得安装gcc以使另一个软件正常工作，我担心卸载它可能会导致其他问题。
非常感谢任何建议！
以下是更多信息：
我正在运行OSX 10.7.5 Lion，我有GCC版本4.2.1，以及安装了命令行工具的XCode 4.4.1。
按照http://heasarc.gsfc.nasa.gov/fitsio/mac_universal_binary.html上的说明，我发生错误时尝试安装名为cfitsio的IRAF包：
解压缩cfitsio源代码tar文件 cd cfitsio setenv CFLAGS“-arch ppc -arch i386 -g -O2” 然后继续使用标准的cfitsio构建，即： 。/配置 使 make install
问题是我在./configure步骤中遇到错误，与gcc有关。这是config.log：

以下是有关我机器上gcc的更多信息：
[vpnls09:~] kaleida% which gcc
/usr/bin/gcc
[vpnls09:~] kaleida% gcc -version
i686-apple-darwin11-llvm-gcc-4.2: no input files

i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)
我还用“Hello World”脚本测试了gcc：
[vpnls09:~/src] kaleida% more hello.c
/* hello.c - demo for os x */
#include<stdio.h>
int main(void){
printf("Hello world\n");
return 0;
}
[vpnls09:~/src] kaleida% gcc -o hello.o -c hello.c
[vpnls09:~/src] kaleida% make hello
cc hello.o -o hello
[vpnls09:~/src] kaleida% ./hello
Hello world
有关如何解决此问题的任何想法？
提前致谢！
