Regardless of the sources I tried (plain Vanilla, Gentoo or latest git version) I cannot build an UML. I always get: n22 /usr/src/linux-2.6.21-gentoo-r4 # make linux ARCH=um scripts/kconfig/conf -s arch/um/Kconfig net/bluetooth/hidp/Kconfig:4:warning: 'select' used by config symbol 'BT_HIDP' refer to undefined symbol 'HID' SYMLINK arch/um/include/kern_constants.h SYMLINK include/asm-um/arch SYMLINK arch/um/include/sysdep SYMLINK arch/um/os SYMLINK include/asm-um/archparam.h SYMLINK include/asm-um/system.h SYMLINK include/asm-um/sigcontext.h SYMLINK include/asm-um/processor.h SYMLINK include/asm-um/ptrace.h SYMLINK include/asm-um/module.h SYMLINK include/asm-um/vm-flags.h SYMLINK include/asm-um/elf.h SYMLINK include/asm-um/host_ldt.h CHK arch/um/include/uml-config.h UPD arch/um/include/uml-config.h CC arch/um/sys-i386/user-offsets.s arch/um/sys-i386/user-offsets.c:4:22: error: asm/user.h: No such file or directory arch/um/sys-i386/user-offsets.c: In function 'foo': arch/um/sys-i386/user-offsets.c:51: error: invalid application of 'sizeof' to incomplete type 'struct user_i387_struct' arch/um/sys-i386/user-offsets.c:52: error: invalid application of 'sizeof' to incomplete type 'struct user_fxsr_struct' arch/um/sys-i386/user-offsets.c:70: error: invalid application of 'sizeof' to incomplete type 'struct user_regs_struct' make[1]: *** [arch/um/sys-i386/user-offsets.s] Error 1 make: *** [arch/um/sys-i386/user-offsets.s] Error 2 Reproducible: Always

After I applied the patch (see below) I run into another compile error. I'd like to reopen this bug b/c (1) there is an issue with current kernels too (2) there is another issue beside the inlcude of user.h (3) I cannot reopen the original bug #170544 Here's what I got from Jeff Dike: On Mon, Aug 20, 2007 at 05:30:37PM +0200, Toralf Förster wrote: > I found this in /usr/include/sys/user.h (the file was installed from > glibc-2.5-r4): sys/user works for me - try the patch below.

Yes, as said on the other bug, this is known upstream but not fixed in vanilla kernel yet; so you'll have to wait until it gets in, or use the patched usermode-sources meanwhile. *** This bug has been marked as a duplicate of bug 182089 ***
