Hi,

 

I am attempting to build openmpi 1.6.2 using a customized toolchain built using yocto for an ARMv5 target.

I build with the following commands with the toolchain in my path

 

CFLAGS=-march=armv5

./configure --host=arm-prysm-linux-gnueabi --build=i686-pc-linux-gnu CFLAGS=-march=armv5

 

However, the build halts after a few minutes with the following error :

 

rm -f atomic-asm.S

ln -s "../../opal/asm/generated/atomic-local.s" atomic-asm.S

  CPPAS  atomic-asm.lo

atomic-asm.S: Assembler messages:

Kindly guide me.

Anup
