Removal of include/linux/config.h file in 2.6.19 kernel

The file include/linux/config.h has been removed from 2.6.19 kernel. So remember this if you build your favorite module against the new 2.6.19 kernel and you get an error similar to this:

In file included from /usr/src/modules/qc-usb-0.6.4/qc-driver.c:47:
/usr/src/modules/qc-usb-0.6.4/quickcam.h:79:26: linux/config.h: No such file or directory

Thats because there is no more include/linux/config.h file in 2.6.19. This is from the Changelog:

sh: Kill off remaining config.h references.

A few of these managed to sneak back in, get rid of them once
and for all.

What I did was to modify the code and commented out all instances of the include statement :
#include <linux/config.h>
This seemed to work. Another trick that worked was just do this:
touch /usr/src/linux/include/linux/config.h

Thanks for the information. It will be usefull.

well the .h files are not from the main kernel package ,they are from the devel package(unless you built it yourself)
if kernel-devel(or -source depending on distro) isn't installed there wouldn't be any useful includes

The reason I posted this is for people who have the kernel sources installed and are trying to build a module against the sources and are getting the error I mentioned. You wouldn't be trying to build a module for the 2.6.19 kernel unless you had the sources installed.

Actually there is not much to the file:

Code:

#ifndef _LINUX_CONFIG_H

#define _LINUX_CONFIG_H

/* This file is no longer in use and kept only for backward compatibility.

 * autoconf.h is now included via -imacros on the commandline

 */

#include <linux/autoconf.h>



#endif

So if you have problems you could probably just add to code here to your module.c file.
