Re: [ts-7000] Re: Ts 7800 cross compilation problems: ld-linux.so.3

[Frank <>]

I have the kernel set up to (try and) compile entirely on the 7800.  I copied the .config-oct8 to .config, commented out the CROSS_COMPILE in the Makefile, and did a make.

After about a minute, I got this:

   SYMLINK include/asm -> include/asm-arm
  CC      arch/arm/kernel/asm-offsets.s
cc1: error: invalid option `abi=aapcs-linux'
make[1]: *** [arch/arm/kernel/asm-offsets.s] Error 1
make: *** [prepare0] Error 2

I found this conditional in the arch/arm/Makefile

ifeq ($(CONFIG_AEABI),y)
CFLAGS_ABI      :=-mabi=aapcs-linux -mno-thumb-interwork
else
CFLAGS_ABI      :=$(call cc-option,-mapcs-32,-mabi=apcs-gnu) $(call cc-option,-m
no-thumb-interwork,)
endif

I could obviously set CONFIG_AEABI to 'n' in the .config, but I wonder why it was there in the first place if things would not compile with it set to 'y'.

Any takers?

Thanks,

I had the same issue as what you have now, and found out the
debian built on the ts7800 actually is not generated from the
cross-tool from the ts. For example, gcc-3.3.5 on the ts7800, which
may be from Marvell, only supports the legacy ABI, while the 2005q3
from the CodeSourcery provides the gcc-3.4.4 with the ARM EABI for
ARMv5t, and the 2007q1 has gcc-4.2.0 for ARMv4 EABI. This is reason
why a shared library (see fulatoro's dynamically linked helloworld's
case) failed. Moreover, the cross-compiling environment provided from
the TS actually won't work with the current setup on the ts7800.
To fix this problem, you have to either directly built your
application on the ts7800, or set up a NSF with your desktop
development environment. But the best way is to rebuilt whole system
on the ts7800 with new cross-tool. I downloaded the 2007q3 already,
and will do it when having a free time.

Good luck!
