Guessing kernel options for modules

[Der_Caveman]

Hi!

I have got a set top box with linux kernel 2.6.9 installed (marusys, ibm powerpc stb04500).

I grabbed the linux kernel from hxxp://stb.marusys.com and built a cross compiler using crosstool-ng.

I need loop support so I built it as a module, but the module won't load on the set top box:

insmod: cannot insert `loop.ko': Invalid module format (-1): Exec format error

How do I find the right configure options to build a proper kernel module?

I have to say that I am not using the gcc, glibc and binutils which were used to build the "box software"- could this be a problem?

TIA,
Heiko.

Since you are trying to build compiler using crosstools, following packages are required
gcc, glibc, binutils etc. or you can download readly available cross compiler.

I compiled the kernel with the crosstools-ng cross compiler (host: linux x86; target: linux ppc) on my desktop system, but the compiled modules won't load on the set top box.

Just now I found (on the same website ) a precompiled cross compiler for the box (host: linux x86; target: linux ppc). I built the kernel module and it loads!

So the gcc, glibc, binutils "combo" has influence on kernel modules...

Thanks,
