Gilles,
oops - yes, CFLAGS. But I also saw this posting:
https://www.open-mpi.org/community/lists/users/2013/01/21111.php
where CCASFLAGS is used (I assume because for asm). I'm trying
this flag when I configure Open MPI.
I tried using the CCASFLAGS flag from the above link and it didn't work.
The error
now reads:

I used the configure flag CCASFLAGS=-march=armv7-a
Not sure if that is correct or not. I'm guessing I'm using the wrong
architecture for the Pi 2. Suggestions?
Thanks!
Jeff
Thanks!
Jeff
Jeff,
shall I assume you made a typo and wrote CCFLAGS instead of CFLAGS ?
also, can you double check the flags are correctly passed to the
assembler with
cd opal/asm
make -n atomic-asm.lo
Cheers,
Gilles

I was doing some googling and I saw where I need to specify
CCFLAGS when I run configure but I want to make 100% sure
I have the right arguments. Can anyone help?
Thanks!
Jeff
P.S. I'd rather build OpenMPI from source rather than use the
pre-built
packages in the Raspbian repository.
