Every x86_64 box is also a potential of an x86_32 cross compilation environment, right?. Almost because for instance in Fedora 12 I had to: yum install glibc-devel.i686 for it to work (On top of the regular Kernel development packages) So I tried: []$ make ARCH=um SUBARCH=i386 KBUILD_OUTPUT=.build_i386_um defconfig []$ make ARCH=um SUBARCH=i386 KBUILD_OUTPUT=.build_i386_um And it all worked very nice just as with x86_64. What is you box environment? Distro, Arch, version of gcc-for-i386 ...? I would like to help resolve it. Since I decided that I should be watching out for ARCH=um, before breakage is put into Linus tree, like the last 4 Kernels. Meanwhile I have setup a cron job for every-night to checkout linux-next and "make". As a backup for above, until it is fixed. Anything else I can contribute to this cause?
