insmod problem

[Marco Schramel]

Hi,

we use a custom mpc8270 system. Everything works fine.
Now i have to handle some float values in a device driver. If i insert the compiled module my target prints out 

insmod: unresolved symbol __addsf3
insmod: unresolved symbol __floatsisf

Are there any missing libraries ?

Any other ideas?

Best regards

Marco

You're using floating arithmetic in the kernel.

That's not supported.

Just for my edification:  Is floating point itself not supported (floating
point register
corruption or something like that) or just linking to user space libraries?

Use of floating point registers and instructions.  Its possible to use=20=

FP in rare cases inside the kernel buts its extremely discouraged.

Can you please provide your .config file?
I'm mostly curious about
CONFIG_MODVERSIONS
CONFIG_MODULE_FORCE_LOAD

OK.  These should be fine.

This seems to be the culprit:
>> yaffs: unknown relocation: 40

It indicates that apply_relocate() is failing with -ENOEXEC
where it doesn't know the r_info code "40".
It could be a problem with your cross-platform linker.
