[Llvm-bgq-discuss] Exec format error

[Biddiscombe, John A.]

I resolved the problem this morning when I got back to the machine. I had been setting TOOLCHAIN_FILE instead of CMAKE_TOOLCHAIN_FILE and messed up my builds. the executables are now running.

Apologies for the noise

JB

Subject: [Llvm-bgq-discuss] Exec format error

Hello,

our machine is up and running again and I tried a new compile using the rpms from a couple of days ago.
Compile went ok, I used cmake and didn't use mpi wrappers from clang, but instead invoked cmake with the following cache vars (at end of email) to hopefully give the same result.

When executing a test job, I get an unexpected error

[biddisco at bbpbg1 testing]$ salloc -N 1
salloc: Granted job allocation 2120
salloc: Block RMP18Se222856626 is ready for job
[biddisco at bbpbg1 testing]$ srun -n 1 /scratch5_256_1/bgq/biddisco/build/hdftests/bin/TestHDF5Compound
2013-09-18 22:35:31.802 (FATAL) [0xfffb6688cd0] 20651:ibm.runjob.client.Job: could not start job: job failed to start
2013-09-18 22:35:31.803 (FATAL) [0xfffb6688cd0] 20651:ibm.runjob.client.Job: Load failed on Q04-I2-J01: Application executable ELF header contains invalid value, errno 8 Exec format error

Looks as though I've somehow compiled for the wrong architecture. Is there an easy fix like some missing compile flag/option?

many thanks

JB
