错误：没有可在其中搜索 stdio.h 的包含路径
我以前能够编译 C 程序，但现在不能：
$ cat helloworld.c
#include <stdio.h>
int main(void)
{
printf("Hello, world!\n");
return 0;
}
$ gcc helloworld.c
helloworld.c:1:19: error: no include path in which to search for stdio.h
是的，我有 /usr/include/stdio.h 。是的，build-essentials 已安装。
在我修改 ~/.bashrc 以运行用户目录中安装的程序后，此问题开始出现。我知道这是错误的，因为如果我删除 ~/.bashrc，它就会起作用。
什么环境变量会将 /usr/include 隐藏为包含路径？
I used to be able to compile C programs, but now I can't:
$ cat helloworld.c
#include <stdio.h>
int main(void)
{
printf("Hello, world!\n");
return 0;
}
$ gcc helloworld.c
helloworld.c:1:19: error: no include path in which to search for stdio.h
Yes, I do have /usr/include/stdio.h . Yes, build-essentials is installed.
This problem began after I modified my ~/.bashrc to run a program installed in my user directory. I know this is what's wrong because if I remove ~/.bashrc, it works.
What environment variable would be shadowing /usr/include as an include path?

问题是我的 PATH 中有另一个 GCC：
当我尝试编译“Hello World”时，它正在运行 68000 的编译器，而不是我的系统编译器：D
我在我的
~/.bashrc 中有这个：由于路径是按顺序扫描的，因此首先会看到
/home/joey/gcc4ti/bin中的gcc。我把它改为：The problem was that I had another GCC in my PATH:
When I was trying to compile "Hello World", it was running a compiler for a 68000, not my system compiler :D
I had this in my
~/.bashrc:Because paths are scanned in order, the
gccin/home/joey/gcc4ti/binis seen first. I changed it to:
