• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Luke Macken (RETIRED) 2004-01-16 11:24:30 UTC]

Using the same .config file that I previously compiled 2.6.1-mm1 with, I get the following error when running 'make' in linux-2.6.1-mm4:

Created attachment 23940 [details]
My Kernel Configuration File

My .config file that works fine in 2.6.1-mm1, but produces the error in -mm4

Did you run make oldconfig? Did you choose a cpu type when it asked you to?

[Comment 3 Luke Macken (RETIRED) 2004-01-16 14:07:31 UTC]

Apparently kernel configs from mm1 aren't compatable with mm4.  I had to manually go in an select the processor type from menuconfig.  Sorry for overlooking this, but I made the assumption that they would be compable.

I'll add a warning to the ebuild to do this
