Re: [Starpu-devel] hwloc detection problem when configuring starpu-svn-trunk and starpu-1.2.0rc5

[Nathalie Furmento <nathalie.furmento@labri.fr>]

Hi Lucas,

Could you also please send the config.log file of StarPU?

configure.ac checks the availability of the library with

       LDFLAGS="${SAVED_LDFLAGS} -L$hwloc_dir/lib"
       AC_HAVE_LIBRARY([hwloc],[have_valid_hwloc=yes],[have_valid_hwloc=no])

Could you check the contents of the directory /home/lschnorr/spack-orion/opt/spack/linux-x86_64/gcc-6.1.0/hwloc-1.11.3-j3wlufl4afo5kvid3vv4rutn55ljz2nx/lib ?

Thanks,

Nathalie

Hi,

I am using spack to install Starpu. Spack has been installed this way:

git clone https://github.com/fpruvost/spack.git;
cd spack;
git checkout morse
source share/spack/setup-env.sh

Then, I launch starpu installation this way:

$ spack install -v -n --keep-stage starpu@svn-trunk+fxt~opencl %gcc@6.1.0
==> Installing starpu
==> fxt is already installed in /home/lschnorr/spack-orion/opt/spack/linux-x86_64/gcc-6.1.0/fxt-0.3.1-7cplb2duxldnevckobjnofq6tgpxffck

I am attaching the corresponding spack-build.out.

The problem is that starpu's configure script is not taking into account :

--with-hwloc=/home/lschnorr/spack-orion/opt/spack/linux-x86_64/gcc-6.1.0/hwloc-1.11.3-j3wlufl4afo5kvid3vv4rutn55ljz2nx

When attempting to link against hwloc. The header is correctly found. I've already tried to edit the configure.ac, but without success. My system is a debian testing updated today (currently deployed in one machine of the orion cluster).
$ uname -a
Linux orion-4.lyon.grid5000.fr 4.6.0-1-amd64 #1 SMP Debian 4.6.4-1 (2016-07-18) x86_64 GNU/Linux
lschnorr@orion-4:~/spack-orion$

Any ideas how to overcome this problem?

I tested also against 1.2.0rc5 but the same problem happens.

Thanks
Lucas
