Building kernel 2.4.20-8 for ARM

Hello!

I'm trying to build a kernel for ARM-platform.

I use RedHat 9 with kernel 2.4.20 as my host-platform. The cross toolchain was build myself (binutils-2.10.1, gcc-2.95.3, glibc-2.2.3 with linuxthreads). I decided to use default config (I took rpc, integrator for my experiments).

#make ARCH=arm CROSS_COMPILE=arm-linux- clean ....it all goes well #make ARCH=arm CROSS_COMPILE=arm-linux- dep .... got the errors (sorry for long listing)

What could you advice me to do to solve this issue ?

Big thanks in advance!

Maybe the linux.embedded group would be more apropriate to ask this question but...

I think it would help if you rather used a proper kernel instead of redhat one. Though theoreticaly the kernel has support for architectures other than x86, I think it is compiles only for x86, not to mention redhat applies literally hundreds of patches to Tosatti's kernel. Start with pristine kernel and apply the ARM patches apropriate for your target you may find at

Notice that if your target is pxa255 based, there is an extra patch by Nicolas Pitre. There might be other specific patches for some other targets as well.

HTH.

Hello!

I fetched the kernel from ftp.kernel.org. But I didn't applied any patches from ARM-site. May be this is the reason?

Well, I did all steps required - fetched the kernel, patched it with ARM-patch. But it didn't help. Still errors... Any ideas ?

Looks like you're doing something wrong. I have make the very same procedure several times the latest days with no problem whatsoever. I am using the toolchain that came with the development kit though (Arcom Viper). I suggest you try uncompress the linux.org kernel inside your home, patch it and try again. BTW, after compiling the libc, have you compiled the compiler? The first compiler you build is rather limited AFAIK and is aimed at libc creation mainly.

Regards.

Elder.

Hello!

Yes. I did it just you said: uncompressed the kernel in my work directory, patched it eith ARM-site patch. Then I build boot-gcc (i.e. without c++ support), then glibc anfd finally full gcc.
