I just installed a new kernel for my Slackware 10.0, 2.6.7, and I removed all of the old kernel 2.4.26 stuff including the headers. Now, programs won't compile because I have no headers. How do I get the headers for my new 2.6.7 kernel?

Create a symbolic link called /usr/src/linux, pointing to the actual kernel source root directory. Say, something along these lines: ln -s /usr/src/linux-2.6.7 /usr/src/linux

Kernel headers are include files that define functions that some programs that interact closely with the kernel use.

also as a note: there should be no symlinks to the kernel headers, this can sometimes break programs that try to compile if you switch kernels

/usr/include/linux as well as the other kernel headers should not be symlinks, if it is you might want to remove this,

I already did that... that's not what the headers are. That's the source code. I'm talking about the files in /usr/include/linux. I just did some test to see exactly what was going wrong and this is what I got. Programs compiled successfully before I did anything (obviously). Then, when I compiled the 2.6.7 kernel they still compiled successfully. Then, I uninstalled the all of the old kernel stuff and the programs would not compile. Then, I reinstalled the 2.4.26 headers and they compiled again. So it seems that the 2.4.26 headers are working with the 2.6.7 kernel somehow. Is this safe to do? And none of you answered my question about how to get the 2.6.7 kernel headers.

the headers are in the kernel source itself

/usr/src/linux/include/linux and /usr/src/linux/include/asm(pick one, if not sure, then generic should work fine)

this assumes /usr/src/linux is a symlink to the 2.6.7 tree, but be warned, some programs might get errors if you compile against different source headers

just override the headers in /usr/include/linux and /usr/include/asm

those should not be symlinks, if they are, remove them

what does that mean? should i use the old 2.4.26 headers on my 2.6.7 kernel or copy the 2.6.7 headers over to /usr/include/linux?

/usr/include/linux should contain the headers of the kernel that glibc was compiled against. http://lfs.securewebservices.co.uk/l...elheaders.html

ah ok thanks that's what i wanted to know
