fglrx and slackware 14-current

so when i try to install the driver installer-catalyst-13.1-linux-x86.x86_64.run
or when i try to generate the driver package, this error shows up in the /usr/share/ati/fglrx-install.log

file: /lib/modules/3.9.5/build/include/linux/version.h
ERROR: I didn't make module
[Error] Generate Package - error generating package : Slackware/Slackware

after i copied the version.h file from the src folder these errors ended up in the file:

maybe the lastest version of the headers are messed up or something.
i have slackware current at the last update.
any advice? thanks.

Did you update your kernel headers by chance?

i ran a complete update to --current with slackpkg, that installed new kernel files.

a/kernel-firmware-20130610git-noarch-1.txz: Upgraded.
a/kernel-generic-3.9.5-x86_64-1.txz: Upgraded.
a/kernel-huge-3.9.5-x86_64-1.txz: Upgraded.
a/kernel-modules-3.9.5-x86_64-1.txz: Upgraded.

d/kernel-headers-3.9.5-x86-1.txz: Upgraded.
k/kernel-source-3.9.5-noarch-1.txz: Upgraded.

By chance was there an update to glibc as well?

this is what the changelog says

l/glibc-2.17-x86_64-4.txz:  Rebuilt.
l/glibc-i18n-2.17-x86_64-4.txz:  Rebuilt.
l/glibc-profile-2.17-x86_64-4.txz:  Rebuilt.

i deleted the version.h and instead i made a symbolic link.
this shows up in the log file:

[Error] Generate Package - error generating package : Slackware/Slackware

amd-driver-installer-catalyst-13-4-x86.x86_64.run compiles and runs fine here on -current.

i made a new installation of slackware current, then i install the beta driver of AMD 13.6 that adds support for my video card. everything seems to work fine.

The kernel headers should really never be updated unless you update glibc. The kernel headers really aren't a part of the Linux Kernel, but are more-so, GLibC-Kernel-Headers. In reality the package has suffered a long time mislabeling, which has led to incidents like this.

Unless you update GLibC and the Kernel Headers equally, it will break your compiler.
