2015-06-10 Thread Jeff Layton


Gilles,

I installed the 4.8 series of compilers on the Pi 2 (gcc, g++, and 
gfortran).

I did a fresh untar of openmpi-1.8.5. I set the environment variables
CC, CXX, and FC to point to the 4.8 compilers. However, the build failed
again.

Re: [OMPI users] Building OpenMPI on Raspberry Pi 2

2015-06-09 Thread Gilles Gouaillardet


Jeff,

Raspbian is built for armv6
(unlike linaro which is built for armv7)

that being said, you are running on an armv7 cpu, so i am not sure 
"cross-compiling"
is appropriate. (e.g. if you run a 32 bits gcc binary on an x86_64 os to 
build a x86_64 binary,

is this called cross compilation ?)

my guess is raspbian gcc 4.6 is not able to compile for armv7, even with 
some extra flags.


can you try
sudo apt-get install gcc-4.8 g++-4.8
and configure with CC=gcc48 CXX=g++48
(or whatever the gcc 4.8 compiler name is)

if that works, i will think of updating configure so it fails with an 
understandable error message

when building for armv6

Cheers,

Gilles

Gilles,

I was looking in Raspbian a little and do you know what I found?
When I do "gcc -v" it says it was built with "--with-arch=armv6".
Since I'm trying to compile on a Pi 2, doesn't this mean I'm
cross-compiling?

Thanks!

Jeff


Jeff,

btw, did you try a pI 1 before a pi2 ?

I checked some forums, and you will likely have to upgrade gcc to 4.8

a simpler option could be linaro

Jeff,

dmb is available only on ARMv7 (Pi 2)

if i remember correctly, you are building Open MPI on
ARMv7 as well (Pi 2),
so this is not a cross compilation issue.

if you configure with -march=armv7, the relevant log is
libtool: compile:  gcc -std=gnu99 -DHAVE_CONFIG_H -I.

I'm not sure how to check if gcc can generate armv7 code.
I'm using Raspbian and I'm just using the default compilers
that come with it (I think it's gcc 4.6.3).

Thanks!

Jeff

Jeff,

dmb is available only on ARMv7 (Pi 2)

if i remember correctly, you are building Open MPI on ARMv7 as
well (Pi 2),
so this is not a cross compilation issue.

if you configure with -march=armv7, the relevant log is
libtool: compile:  gcc -std=gnu99 -DHAVE_CONFIG_H -I.
-I../../opal/include -I../../orte/include -I../../ompi/include
-I../../oshmem/include
-I../../opal/mca/hwloc/hwloc191/hwloc/include/private/autogen
-I../../opal/mca/hwloc/hwloc191/hwloc/include/hwloc/autogen
-I../..
-I/work/pi/src/openmpi-1.8.5/opal/mca/hwloc/hwloc191/hwloc/include
-I/work/pi/src/openmpi-1.8.5/opal/mca/event/libevent2021/libevent

-I/work/pi/src/openmpi-1.8.5/opal/mca/event/libevent2021/libevent/include
-march=armv7 -MT atomic-asm.lo -MD -MP -MF
.deps/atomic-asm.Tpo -c atomic-asm.S  -fPIC -DPIC -o
.libs/atomic-asm.o^M
atomic-asm.S:1:0: error: target CPU does not support ARM mode

which is very puzzling ...

can you confirm
1) you are not cross compiling
2) your gcc can generate code for armv7 ?

Cheers,

Gilles

Jeff,

btw, did you try a pI 1 before a pi2 ?

I checked some forums, and you will likely have to upgrade gcc to 4.8

a simpler option could be linaro

Re: [OMPI users] Building OpenMPI on Raspberry Pi 2

2015-06-08 Thread Jeff Layton


Jeff,

Sorry - I was traveling for a week and didn't have to the RPi.


What happens if you don't supply CCASFLAGS at all?



The output from "make" is below. It died when it tried to compile
atomic-local. It says the processor doesn't support ARM mode "dmb".

Thanks!

Jeff

Hmm -- I'm confused.  You show output from "make" in your previous mails...?

Ok, thanks.  Here's the problematic compile command:

-
gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I../../opal/include -I../../orte/include 
-I../../ompi/include -I../../oshmem/include 
-I../../opal/mca/hwloc/hwloc191/hwloc/include/private/autogen 
-I../../opal/mca/hwloc/hwloc191/hwloc/include/hwloc/autogen -I../.. 
-I/work/pi/src/openmpi-1.8.5/opal/mca/hwloc/hwloc191/hwloc/include 
-I/work/pi/src/openmpi-1.8.5/opal/mca/event/libevent2021/libevent 
-I/work/pi/src/openmpi-1.8.5/opal/mca/event/libevent2021/libevent/include 
-march=armv7 -MT atomic-asm.lo -MD -MP -MF .deps/atomic-asm.Tpo -c atomic-asm.S 
 -fPIC -DPIC -o .libs/atomic-asm.o
-

Stripping out the -D's and -I's which aren't important for this discussion, 
we're left with:

-
gcc -std=gnu99 -march=armv7 -MT atomic-asm.lo -MD -MP -MF .deps/atomic-asm.Tpo 
-c atomic-asm.S  -fPIC -DPIC -o .libs/atomic-asm.o
-

So it looks like the -march=armv7 is, indeed, the problematic switch.

FWIW, a few lines above it, this line succeeded:

-
gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I../../opal/include -I../../orte/include 
-I../../ompi/include -I../../oshmem/include 
-I../../opal/mca/hwloc/hwloc191/hwloc/include/private/autogen 
-I../../opal/mca/hwloc/hwloc191/hwloc/include/hwloc/autogen -I../.. 
-I/work/pi/src/openmpi-1.8.5/opal/mca/hwloc/hwloc191/hwloc/include 
-I/work/pi/src/openmpi-1.8.5/opal/mca/event/libevent2021/libevent 
-I/work/pi/src/openmpi-1.8.5/opal/mca/event/libevent2021/libevent/include -O3 
-DNDEBUG -finline-functions -fno-strict-aliasing -pthread -MT asm.lo -MD -MP 
-MF .deps/asm.Tpo -c asm.c  -fPIC -DPIC -o .libs/asm.o
-

Which, as you notice, does *not* have the -march=armv7 token (because it's 
compiling a C file, not an assembly file).

 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?

What happens if you don't supply CCASFLAGS at all?

Jeff,

The error happens during the configure step before compiling.
However, I ran the make command as you indicated and I'm
attaching the output to this email.

Thanks!

Can you send the output of "make V=1"?

That will show the exact command line that is being used to build that file.

As you are not cross-compiling I would expect gcc to use the right assembly by 
default. What is happening is you force the native mode (-march=native) ?

Gilles,

oops - yes, CFLAGS. But I also saw this posting:

https://www.open-mpi.org/community/lists/users/2013/01/2.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,

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,
