Preventing :make in VIM from going to a warning

Question

I have a warning I can not easily remove from my build, every time i run ":make" from inside vim the quickfix takes me to some header file I don't care about. How can I prevent VIM from doing this and only showing me warnings and errors I do care about?

As Luc Hermite said, it is possible to ignore warnings using 'errorformat'option. Adjusting this option is a little bit complicated; it may be helpful to check $VIMRUNTIME/compiler for some examples.

When working with avr-gcc and C++ some annoying warnings like this

tests.cpp:492: warning: only initialized variables can be placed into program memory area

shows up, and it is likely to be result of a compiler fault.

To avoid that this warnings being displayed on quickfix window I've add this to ~/.vimrc:

compiler gcc
set errorformat^=%-G%f:%l:\ %tarning:\ only\ initialized\ varia
            \bles\ can\ be\ placed\ into\ program\ memory\ area

The %-G can be used to specify patterns to be ignored. The ^= in set errorformat^=... is used to prepend the ignored warning pattern to 'errorformat' -- using += (set errorformat+=...) would append to the option and wouldn't work, as 'errorformat' is a list of formats and the first one that matches is used, thus the "normal" warning pattern would apply instead.

Maybe you could adapt these settings for your environment.
