Hi, I just got a bug report that klibc doesn't compile on s390: KLIBCCC usr/klibc/libgcc/__clzsi2.o KLIBCCC usr/klibc/libgcc/__clzdi2.o usr/klibc/libgcc/__clzdi2.c: In function `__clzdi2': usr/klibc/libgcc/__clzdi2.c:24: warning: implicit declaration of function `__builtin_clz' This looks like a common problem, because __builtin_clz is available since gcc 3....

...dcode the relative path of mktokens in the rule; another solution could be changing mktokens to output on the stdout and redirect it to the correct file. I've tested the patch with and without O= and it works as expected. The compilation then stops at dash anyway, with the following error: KLIBCCC usr/dash/redir.o KLIBCCC usr/dash/show.o KLIBCCC usr/dash/trap.o KLIBCCC usr/dash/output.o KLIBCCC usr/dash/bltin/printf.o KLIBCCC usr/dash/system.o KLIBCCC usr/dash/bltin/test.o KLIBCCC usr/dash/bltin/times.o KLIBCCC usr/dash/var.o KLIBCLD usr/dash/sh usr/dash/builtins.o:(.rodata...

Hi, From the Makefile I figured that to build klibc where the kernel was built with O=/someotherdir, you need to do: make KLIBCKERNELOBJ=/someotherdir KBUILD_SRC=1 Everything seems fine though, but it fails to link dash with: ----- KLIBCCC dash/bltin/printf.o KLIBCCC dash/system.o KLIBCCC dash/bltin/test.o KLIBCCC dash/bltin/times.o KLIBCCC dash/var.o GEN dash/init.c KLIBCCC dash/init.o KLIBCLD dash/sh KLIBCLD dash/sh.shared dash/builtins.o:(.rodata+0x68): undefined reference to `bgcmd' dash/builtins.o:(.rodat...
