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

make[2]: *** [scripts/Makefile.vmlinux:77: vmlinux] Error 1
make[1]: *** [/usr/src/linux-6.13.0-gentoo/Makefile:1227: vmlinux] Error 2
make: *** [Makefile:251: __sub-make] Error 2 |
To get to this I do the following | Code: | 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: | 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. |

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. |

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. |
