[U-Boot-Users] Building U-Boot with GCC3.4.0
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 o-builtin -ffreestanding -nostdinc -isystem /usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/include -pipe -DCONFIG_M68K -D__M68K_ _ -m5307 -c -o cpu/mcf52x2/start.o /home/JimMcNamara/u-boot-1.1.1/cpu/mcf52x2/start.S /home/JimMcNamara/u-boot-1.1.1/cpu/mcf52x2/start.S: Assembler messages: /home/JimMcNamara/u-boot-1.1.1/cpu/mcf52x2/start.S:316: Fatal error: Tried 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.
/home/JimMcNamara/u-boot-1.1.1/cpu/mcf52x2/start.S
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.

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??
