I was trying to cross-compile a program for ARM. While compiling I was very much irritated as I had to look for a number of dependencies e.g fatal error: abc/xyz.h: No such file or directory compilation terminated.

After ensuring that compiler gets the missing files, when I recompiled, I got same error for about 30 files.

I have no idea if that is normal behaviour.

If it is normal, is there a method which can help the compiler find the dependencies on its own?

If that is not normal, then please explain what I'm doing wrong.

If your computer has enough processing core you can try to speed up the compilation using -j option. Apart from this advice, I have no idea about the problem your are facing. (Check this for -j options linuxtopia.org/online_books/linux_kernel/kernel_configuration/…) –  Web-E Jun 27 '12 at 11:50

Are you looking for something like the -M flag in gcc? http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Preprocessor-Options.html
