Toolchain and linux-2.6.12

[Koen]

Hello did anyone build a toolchain for for a at91 kernel?
When I try it I always get somewhere errors does anyone have a despription to make (a recent version eg. gcc-2.4.2, glibc-2.3.3)
With the prebuild version I found the headers for at91 are missing (and also the gcj compiler)
The examples for building are most of the time for the linux-2.4

i use binutils 2.16.1 , and cross-3.2
only by using them got kernel.

I asume that you use the prebuild toolchain 3.2 from 'arm.linux.org.uk'
When I try to use it I get a error 'Your compiler is too buggy; it is known to miscompile kernels'
Maybe this had something to do with the binutils 2.16.1, but how do you combine the binutils with the already build toolchain?

[mishal4]

actually kernel is right. cross-comiler chain 3.2 (yes i get it from arm.linux.org.uk)
i just remove testing of compiler version. sorry but i haven't idea how to get "not buggy" toolchain.
about adding binutils.
it is nessesary at least version 2.14. to compile 2.6.x kernel.
so - when you download new binutils use "configure " script to generate installation of the binutils - you just set path to cross compiler (and of course your target).
and you can install new version of binutils.
that's all.
(i understand that my way is not easy but i can't find another sorry)

Hi,
I received the same buggy mesage with 3.0 and 3.2 also.
I could not compile 2.6.12 kernel with either 2.94 or 2.93.

I ended up using crosstool to compile a 3.3 cross compiler.

Check this out kegel.com/crosstool for more information.

Good luck

Hi,

I'm working with the kernel version 2.6.12.6 and the compiler arm-none-linux-gnueabi-gcc-3.4.4 from CodeSourcery.

It works fine and without any compiler errors.

Did you compile U Boot 1.1.3 or 1.1.4 with your compiler. I tried 1.1.4 and I get an error -

hi dguedel:
I use the cross compiler from the web you give above, but when cross compiling the linux-2.6.12 for arm, shows lots of warning:target CPU does not support interworking, and the kernel halts after uncompressing. what is the matter,will you please give me some advice?
I download the gcc3.4.3 from gnu, and still have some errors(can not find the system headers) when building.
Best regards!

Hi,

I was on holiday, so my late reply.

I'm working with the kernel version 2.6.12.6 and the compiler arm-none-linux-gnueabi-gcc-3.4.4 and I get the same warnings (not errors) too 'CPU does not support interworking' but the kernel starts after uncompressing. Which board do you use?

I'm using u-boot-1.1.2 with the compiler 2.95.3 from Atmel and actually I'm trying u-boot-1.1.4 with the compiler arm-none-linux-gnueabi-gcc-3.4.4 but I get the same error messages about EABI version 4 and 0.

Daniel

use 3.2 or 3.3 version of compiler and you will be happy.

Hello,

I try the same with the same error. What do you mean with compiler version 3.2 or 3.3??
I don't want compile the cross compiler.
I use the arm-none-linux-gnueabi from CodeSourcery. It includes the arm-linux-gcc Version 3.4.4 and try to make u-boot 1.1.4

Best Regards
Manuel

if you don't want to compile cross-compiler you will not got nothing. unfortunately. I have spand a lot of time to ensure this. sorry. if you found another way - please give me a note
