[U-Boot-Users] Building U-Boot with GCC3.4.0

[U-Boot-Users] Building U-Boot with GCC3.4.0

[Jim McNamara]

Hi All,

I've been able to get U-Boot to build and run successfully using Linux and
m68k-elf-2.95.3.

What I'm trying to do now is build U-Boot in Cygwin using m68k-elf-3.4.0.
I've applied all the cygwin patches neccessary and any GCC3.4.0 patches I
could find. However, I've run into a problem compiling cpu/mcf52x2/start.S.
This is the error message that I'm getting:-

m68k-elf-gcc -Wa,-gstabs -D__ASSEMBLY__ -g  -Os   -ffixed-d7 -msep-data -D__
KERNEL__ -DTEXT_BASE=0xfe000000 -I/home/JimMcNamara/u-boot-1.1.1/include -fn

to convert PC relative conditional branch to absolute jump
make: *** [cpu/mcf52x2/start.o] Error 1

I've looked at the mail archive and noticed that this problem has been
mentioned before, however I can't find any solution posted. Can anyone give
me some pointers on how to resolve the problem??

Thanks,

Jim...

That's an ancient toolchain...

You're dropping from one extreme into another.

And you're using  old  code.  Use  the  top-of-tree  version  in  CVS
instead.

Please try the current code; if the problem persists, you  will  need
to fix it.

Best regards,

FYI

The 3.4 was the only thing we needed to create our own toolchain that
was at least as performant (binary wise) as a commercial toolchain.

I was able to compile u-boot with the toolchain (buildroot based,
powerpc-linux-uclibc-gcc) but the final linkcing failed (caused a
segfault, Make error 321 or something).

For the time being, I use the ELDK compiler to build u-boot and the
3.4 based toolchain for everything else (including the kernel). I'll
have another look at it in the next weeks or so.

What's the recommended version for use with U-Boot??

Hi Benjamin,

Have a look at the patches posted by Yuli Barcohen (2004-07-19) and Lars
Munch (2004-07-24).

Do a search of the mail archive and you should find them easy enough.

Jim.
