I have been searching for two days and haven't found an answer yet. First My 14.0 was running 3.0.69. My first attempt to upgrade from 14.0->14.1 failed on the first package because my kernel was too old. I upgraded my kernel to 3.12 then was able to upgrade slackware.
While booted with 3.12, attempting to install the nvidia driver 319.49 warns me about the kernel gcc version not matching the installed version. I thought, ok I'll just recompile and reinstall 3.12. Every attempt to compile fails quickly. I don't have the exact error messages but most refer errorno.h and string.h in several include paths. I even tried copying the generic config from 3.10.17.
Next I thought, ok I'll tackle this later and install nvidia driver with 3.10.17 for now. It fails also with errors referring to nv-drm.c, "'drm_fasync' undeclared" and "void valve not ignored".
Have I missed or forgotten something? I have been upgrading slackware versions since 9.1 and compiling my own kernels almost as long and never had this happen.

You need a newer version of the driver to make it work with 3.10 (and newer) kernels.

You need the latest 331.20 or 325.15 in order to get with 3.12 kernel
even better, stay with Slackware 14.1's default kernel and you will be fine with older version of NVidia drivers

the culprit will likely be mismatching glibc, gcc, and kernel headers files, just speculations without seeing any Error messages.

follow my blog, and you have good working lftp, wget, mkinitrd, and lilo, you will upgrade to current.

you also need empty /lib/udev/rules.d, and upgrade new udev package.

good luck.

Thank you for the replies. Sorry for not providing actual error messages. At the time, I wasn't prepared to take a screenshot or save a copy of the logs.
This morning I reinstalled the kernel-source and kernel-headers packages and was able to successfully compile the 3.12 kernel. However, both 319.49 and 325.15 drivers fail to build under the default huge-3.10.17 kernel. I didn't try yet with my new 3.12 kernel. I just downloaded the 331.20 driver and will try it when I get home from work.
Attached is the log file from attempting to install the 325.15 driver from the default huge-3.10.17 kernel.

Driver 331.20 built successfully with kernel 3.12. All is well now. Thanks, guys, for the helpful tips along the way.
