compile problem

[Blake Huff]

Chris:

I'm no expert, but I'll take a swag.

This is happening because the compiler doesn't know where to look for  
stdio.h, probably because it was installed in a "non-standard"  
location.  For example, if it was installed to /usr/local/include/   
instead of /usr/include/ (or wherever the compiler expects it), the  
compiler can't find it.

Long story short, you probably need to locate stdio.h and direct the  
compiler to find it using -I (That's the dash 'eye' option).   So if   
stdio.h is in /usr/local/include/     I would compile with: gcc -I/ 
usr/local/include/ hello.c.

You can also find information on the internet about how to add a non- 
standard directory to the compiler's search path so you don't have to  
do this every time, but I'm lame on that and just use these options  
every time.
