I am working on 32-bit Fedora 14 system. I'm compiling my source code using gcc.
Does anybody know how to disable warnings while compiling c code?
EDIT: Yes i know. Best thing is to fix those Warnings to avoid any undefined/unknown behavior. But currently here, i have written huge code first time and there are lots of error & warning in first compilation. Here i just want to concentrate on errors first and then i will see warnings.

The short answer: Use "-w" to ignore warnings.
To answer your question about disabling specific warnings in GCC, you can enable specific warnings in GCC with -Wxxxx and disable them with -Wno-xxxx. From the GCC Warning Options: You can request many specific warnings with options beginning -W , for example -Wimplicit to request warnings on implicit declarations.
To disable a set of warnings for a given piece of code, you have to start with a “push” pre-processor instruction, then with a disabling instruction for each of the warning you want to suppress, and finish with a “pop” pre-processor instruction. Now let's dive into the code for each compiler.
Unlike compilation errors, warnings don't interrupt the compilation process. They are not errors from the viewpoint of a programming language, but they may be software bugs. However, many compilers can be customized so that their warnings don't stop the compilation process.

Every body tells use -Wall switch with gcc, but you want to disable it. It is not advised, Use debugger to find it.
