I just assumed that it must have been changed in newer versions. But to sum up. I've to compile with '--with-cpu=default32' and all should be fine? Because I have no idea how to pass the -m32 flag just to the 32-bit code generation. Passing it via CFLAGS obviously does not work as it also passes it to the 64 bit code generation.

See the 'still' ? How would the compiler know whether to generate 64bit or 32bit code?? Andreas, I think we both got a bit lost. Lets take a step back. The original problem was that after 2.6.23 cross compiling powerpc/g5_defconfig broke (Regression). Using gcc 4.0.4, powerpc64 target as cross compiler and powerpc target as 32-bit cross compiler. Since 2.6.23-git1 it is now broken. Using gcc 4.1.2 didn't fix this. Neither with --with-cpu=default32 present nor without. So could you please explain to me how I'm supposed to cross compile powerpc/g5_defconfig now? Passing CFLAGS=-m32 didn't help too. Or is it just a new bug in the kernel make system? Just for reference up till 2.6.23 I used the following command: make ARCH=powerpc HOSTCC=gcc-4.0 CROSS_COMPILE=powerpc64-linux- \ CROSS32_COMPILE=powerpc-linux- Thanks, Jan ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev

boot/wrap assumes a biarch toolchain?
Hi, Jan is seeing the following fail: WRAParch/powerpc/boot/zImage.pmac powerpc-linux-objcopy: vmlinux: File format not recognized He is using a cross compile toolchain invoked with the following command line: # make HOSTCC=gcc-4.0 ARCH=powerpc CROSS_COMPILE=powerpc64-linux- CROSS32_COMPILE=powerpc-linux- It seems like boot/wrap wants to use both 64bit and 32bit tools, however it only receives the 32bit path: ifneq ($(CROSS32_COMPILE),) CROSSWRAP := -C $(CROSS32_COMPILE) else ifneq ($(CROSS_COMPILE),) CROSSWRAP := -C $(CROSS_COMPILE) endif endif Thoughts? I guess we have to pass in both cross compile targets. One way to make this go away would be to build binutils as biarch: # configure --target=powerpc-linux --enable-targets=powerpc64-linux ...

Re: boot/wrap assumes a biarch toolchain?
Hi, If you configure your toolchain for powerpc64-linux you get a biarch toolchain by default. I was wondering about people using pre biarch gcc toolchains. But I take your point - I'm guessing binutils has been biarch for a long time. Since we are only calling binutils functions in boot/wrap, maybe we can just do: diff --git a/arch/powerpc/boot/Makefile b/arch/powerpc/boot/Makefile index 18e3271..8961afd 100644 --- a/arch/powerpc/boot/Makefile +++ b/arch/powerpc/boot/Makefile @@ -121,13 +121,9 @@ wrapperbits:= $(extra-y) $(addprefix $(obj)/,addnote hack-coff mktree) \ # # Bits for building various flavours of zImage -ifneq ($(CROSS32_COMPILE),) -CROSSWRAP := -C $(CROSS32_COMPILE) -else ifneq ($(CROSS_COMPILE),) CROSSWRAP := -C $(CROSS_COMPILE) endif -endif # args (to if_changed): 1 = (this rule), 2 = platform, 3 = dts 4=dtb 5=initrd quiet_cmd_wrap = WRAP$@ ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
