Re: [OMPI users] building openmpi-v1.8.5-46-g9f5f498 still breaks

Siegmar -- I don't see any reason why this should be happening to you only sometimes; this code has been unchanged in *forever*. :-( Did your NFS server drift out of time sync with your build machine, perchance? Regardless, I just pushed what should be a workaround to master and I'll PR it

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

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 ?)

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

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

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

Gilles, Let me know if you think I should upgrade to gcc-4.8 and I'll try it. 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

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

Gilles, No I didn't. This is a fresh Raspbian for the Pi 2. I'm using the 05-05-raspbian-wheezy image, plus I did ant apt-get update about a week ago. 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

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

Gilles, Yes I can. I tried a simple C code ("hello world") and it compiled and ran correctly. Thanks! Jeff Jeff, can you gcc -march=armv7-a foo.c Cheers, Gilles On Tuesday, June 9, 2015, Jeff Layton > wrote: Gilles, I'm not

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

Gilles, I'm not cross-compiling - I'm building on the Pi 2. 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

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

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
