I am running Redhat 9. Where is the root directory of my kernel source? I've installed the kernel source rpm. Thanks

In /usr/src

The default responses for each question are correct for most users.
Consult the PCMCIA-HOWTO for additional info about each option.

Linux kernel source directory [/usr/src/linux]: /usr/src
Linux source tree '/usr/src' is incomplete or missing!
See the HOWTO for a list of FTP sites for current kernel sources.

Configuration failed.

Are you trying to compile the kernel in that last post?

No I'm trying to add PCMCIA support so that I can get my wireless card working. The driver for my card is located at:

http://hostap.epitest.fi/

thanks.

well the root directory to the source directory is in /usr/src, but the root directory to the source itself is in /usr/src/linux
check::
ls -alc /usr/src
to see a couple things ::
1) if you have the source installed
2) if the source directory is called or has a symlink to /usr/src/linux

I believe this is all you have to do to install the driver once the Makefile is edit with the path to your kernel source.

'Makefile' includes commands for compiling and installing Host AP
driver for systems using Prism2.5/3-based PCI cards. These cards do not
use pcmcia-cs package. Edit KERNEL_PATH in Makefile to match your
system. Run 'make pci' (this compiles the sources; this step can be
run as non-root user). After the compilation has finished, you can
install hostap_pci.o by running 'make install_pci' (as root). You can
probe PCI bus for Prism2.5/3 PCI cards and initialize the devices by loading
the module ('modprobe hostap_pci').

Did you install the kernel-source i386.rpm or the kernel src.rpm? The former would be correct while the latter is not what you want.

Ok here's what I did that worked. I installed the kernel src.rpm, and I found, that on redhat 9, that created a file in the following directory:

/usr/src/redhat/SOURCES

The file it created was a tarball of all the kernel source files, I untared it, and then symlinked that directory it created to /usr/src/linux, using this command:

ln -s /usr/src/redhat/SOURCES/kernel-2.4.20 /usr/src/linux

Then whenever I used /usr/src/linux as the root directory of the kernel source, every script ran fine. Now my wireless card is working.

That doesn't give you the same source which Red Hat's kernel is built from.

Instead, you install the kernel-source i386.rpm which puts the complete patched and configured kernel source tree into /usr/src/linux-2.4, and you can create a link from /usr/src/linux to /usr/src/linux-2.4 if you need to.
