[SOLVED] gentoo-sources-6.13.0: make error

[ipic]

I'm seeing this when I run make on gentoo-sources-6.13.0:

make[2]: *** [scripts/Makefile.vmlinux:77: vmlinux] Error 1

To get to this I do the following

Code: Select all

cd /usr/src/linux
make distclean
zcat /proc/config.gz >.config
make olddefconfig
make menuconfig # exit with no changes
make -j64

Then, after the failure, I run:
make
which provided the output above

The errors noted above are in the drm area - anyone else seeing this?

The following configuration options in my .config were not set:

Code: Select all

CONFIG_DRM_AMD_ISP
CONFIG_DRM_SIMPLEDRM
CONFIG_SYSFB_SIMPLEFB

When I set these to "Y", the kernel compiled and installed OK.

I'm about to reboot - I'll be back if it works.

[ipic]

Booted OK

My guess would be that CONFIG_DRM_AMD_ISP is not the source of the problem.
It seems more likely that a simple frame buffer device is assumed - especially since the note in the config help says to enable if unsure.

Anyway - this may help someone.

My guess is: You have copied your old .config into 6.13 and did immediately a "make" ... without doing a "make oldconfig" before ...

(if this is true then please read: https://wiki.gentoo.org/wiki/User:Pieti ... fig.22_.3F )

No.
I reproduced it three times, and it's scripted.

It's a kernel bug if it allows configuration options which result in a link failure. There's likely some missing #ifdef based on the CONFIG_* you have disabled.
