I'm trying to compile a program with #includes, and the compiler give me :

hellocurrent.c:1:24: error: linux/init.h: No such file or directory
hellocurrent.c:2:26: error: linux/module.h: No such file or directory
hellocurrent.c:4:25: error: asm/current.h: No such file or directory
hellocurrent.c:5:18: error: list.h: No such file or directory

I have located the files, they are on their directories :

/usr/src/linux-headers-2.6.20-16/include/linux/module.h
.....etc..


I have done :
sudo apt-get install build-essential
sudo aptitude install build-essential
sudo updatedb
....
and no success

Anybody know which could be my problem. Thas has been after update Ubuntu to 7.04

Thanks in advance

What's your compiler command line? Does it contain -I?

Thank you futures past, I finally fix the problem re-installing the gcc.
