Markus, Thank you for your reply! I already feel better knowing that I'm not alone :) Maybe someone might have a clue "Why"....

It seems as if the architecture is i686, then only i686 PAE Debug gets built. I do not know where the problem lies, but ....SOURCES/Makefile.config might be the place where the target kernel build is being selected. To get around it, I edited ...SOURCES/Makefile.config and removed all rules and definitions pertaining to i686-PAE and only left the simple i686 def and rule. PS: I do not know if this is necessary, but after I copied .config to ...SOURCES/config-i686 I also copied it to ...SOURCES/config-x86-generic Then running rpmbuild -v -bb --target=i686 kernel.spec is proceeding without problems MK _________________________________________________________________ Windows Live(tm): Keep your life in sync. http://windowslive.com/explore?ocid=PID23384::T:WLMTAGL:ON:WL:en-US:NF_B R_sync:082009 _______________________________________________ Fedora-kernel-list mailing list Fedora-kernel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-kernel-list
