Include files in subdirectory of /usr/include doest append during compile

Helllo all,

i would like to ask you for help with the next problem:

What is wrong with my settings?
I got Gentoo, gcc 4.5.3, binary compile after update world.

My header files are locating in /usr/include. But also there are a lot of other subdirectories with headers file like libdjvu, alsa, asm .. etc.
And when i write in example.c-file line like #include <ptrace.h> which is located in /usr/include/asm dir, compiler get me an error:
fatal error: ptrace.h: No such file or directory

I suppose that i can solve partialy this problem by creating Makefile with right statements or passing parametre -I to gcc.

My problem is that before i update whole system, i can use header files from any subdirectories i want. Now , after update i cannot do it.

Please tell me, is there some setting where i could set that gcc has to searching for header files over whole /usr/include directory, with subdirectory :)

I hope i am clear with the description of my problem.

Thank you for any ideas

You can use relative paths in #include, eg:

Code:

---

#include <sys/stat.h>
#include <asm/ptrace.h>

---

However, I think the correct include for ptrace is actually <sys/ptrace.h> -- if you look at that, there is a chain of includes that will eventually lead to the file in asm/

If you cd into /usr/include and do this

grep -r ptrace.h ./

you'll find some clues about how this tree works.
