enterprise compiler issue

I was trying to compile something on my pc with IBM XL C/C++ Enterprise Edition V8.0 for AIX I got a error like:

"aaalib.c", line #... something else: 开发者_如何学GoIt refered to a variable that isn't initialized here.

It works fine when compiled with gcc in linux. But I still would like to know why or if anyone has experienced something similar.

It is most likely a valid warning that you are using an uninitialised variable. You should investigate and fix the bug. Just because the code appears to work doesn't mean that you don't have latent bug(s). Post the code for the function where the error occurs if you need help identifying the problem.
