Hello,
today I updated a CentOS 7.6 ppc64le machine to CentOS 7.7. After reboot to the
new kernel (4.18.0-80.7.2.el7.ppc64le) dkms could not build the nvidia-module.
Error-message from dkms:
Compiler version check failed:
The major and minor number of the compiler used to
compile the kernel:
gcc version 8.3.1 20190311 (Red Hat 8.3.1-3) (GCC)
does not match the compiler used here:
cc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)
Output of /proc/version with new kernel running is:
Linux version 4.18.0-80.7.2.el7.ppc64le (mockbuild@xxxxxxxxxxxxxxxxxxxxxxxxxx)
(gcc version 8.3.1 20190311 (Red Hat 8.3.1-3) (GCC)) #1 SMP Thu Sep 12 15:45:05
UTC 2019
Problem seams to be:
The kernel was compiled with gcc-version 8.3.1 and installed is gcc 4.8.5. All
previous kernels were compiled with gcc 4.8.5. See:
#cat /usr/src/kernels/*/include/generated/compile.h |grep LINUX_COMPILER
define LINUX_COMPILER "gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)"
define LINUX_COMPILER "gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)"

define LINUX_COMPILER "gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)"

define LINUX_COMPILER "gcc version 8.3.1 20190311 (Red Hat 8.3.1-3) (GCC)"
Any comments?
Best regards,
Ralf
