Hi All,

I am using for some time the crosstool tool-chain (crosstool-0.43) for the ppc405 of my virtex-4.
It seems to be that the crosstool was not updated for awhile but the glibc and gcc compiler has changed a bit meanwhile.

The latest working configuration to build the toolchain for ppc405 is gcc-4.1.0-glibc-2.3.6.dat
Does any body has tried to adapt the crosstools to use for example glibc 2.7 ?

Another alternative would be to use another tool than crosstool. Could somebody recommend something which can refer to newer version of gcc and glibc .

Best Regards

Miroslaw Dach

Hi Miroslaw,

I'm not sure on what version of gcc and glibc it's using, but I have been using ELDK 4.1 from denx.com. There are newer versions.

Thanks,
John

Hi Jonh,

If I use ml403 (with PPC 405) Did i change the predefined compiler flags for ppc_4xx? The default value is -mcpu=403.

I don't know, I'm not familiar with what you are doing and it's not clear from the message.

I'm sorry.

I want build kernel linux 2.6 for ml403.

I am not sure if this answers your question but to build a 2.6 Linux kernel using the buildroot uclibc ppc cross compiler you would issue the following make command

make ARCH=ppc CROSS_COMPILE=powerpc-linux-uclibc-

If you were using the crosstools compiler rather than buildroot, the CROSS_COMPILE value would change.
For older version of GCC it might require a full path to the crosscompiler.

If you are building a BSP in the powerpc tree use ARCH=powerpc

I am fairly certain that when you are building a Linux kernel it is irrelevant whether you use a glibc or uclibc or ... compiler. The kernel is not going to link against any standard C library, those library functions the kernel uses must be coded in the kernel.

However, when you are cross compiling applications for your target it is a good idea to stick to the same standard C library and associated cross compiler.

Hi,

I'm not sure on what version of gcc and glibc it's using, but I have been using ELDK 4.1 from denx.com. There are newer versions.

The more recent ELDK 4.2 supports 405s and its crosstoolchain uses binutils 2.17.50.0.12, gcc 4.2.2, glibc 2.6 and gdb 6.7.

Cheers
Detlev
