broken builds

[basnijholt]

Currently the build is broken.

This build for PR #33 was still working, while after merging this build is broken.

These are the packages that are changed:

What I tried:

• Building sequential MUMPS (based on the current recipe) with scotch from conda-forge, didn't work
  using

docker run -it --rm condaforge/linux-anvil
git clone https://gitlab.kwant-project.org/basnijholt/kwant.git
cd kwant/
git clone https://github.com/basnijholt/mumps-feedstock.git
cd mumps-feedstock/
git checkout seq
conda build .
conda install --use-local --yes mumps
cd ..
git clone https://gitlab.kwant-project.org/kwant/conda-recipes.git
yum install -y devtoolset-2-gcc-gfortran
conda config --add channels kwant
conda build --python 3.6 conda-recipes/kwant-dev

• Building sequential MUMPS (based on current recipe) with an old version of scotch see this , with (also didn't work):

docker run -it --rm condaforge/linux-anvil
git clone https://gitlab.kwant-project.org/basnijholt/kwant.git
cd kwant/

git clone https://github.com/basnijholt/scotch-feedstock.git
cd scotch-feedstock/
git checkout seq
conda build .
conda install --use-local --yes scotch
cd ..

git clone https://github.com/basnijholt/mumps-feedstock.git
cd mumps-feedstock/
git checkout seq
conda build .
conda install --use-local --yes mumps
cd ..

git clone https://gitlab.kwant-project.org/kwant/conda-recipes.git
yum install -y devtoolset-2-gcc-gfortran
conda config --add channels kwant
conda build --python 3.5 conda-recipes/kwant-dev

• Building using current MUMPS and edits in the build.conf

docker run -it --rm condaforge/linux-anvil
git clone https://gitlab.kwant-project.org/basnijholt/kwant.git
cd kwant/
git clone https://gitlab.kwant-project.org/kwant/conda-recipes.git
cd conda-recipes
git checkout ptscotch
cd ..
yum install -y devtoolset-2-gcc-gfortran
conda config --add channels kwant
conda build --python 3.6 conda-recipes/kwant-dev

Worked:

• Building sequential MUMPS (old working recipe) with an old version of scotch see this , with:

docker run -it --rm condaforge/linux-anvil
git clone https://gitlab.kwant-project.org/basnijholt/kwant.git
cd kwant/

git clone https://github.com/basnijholt/scotch-feedstock.git
cd scotch-feedstock/
git checkout seq
conda build .
conda install --use-local --yes scotch
cd ..

git clone https://github.com/basnijholt/mumps-feedstock.git
cd mumps-feedstock/
git checkout old
conda build .
conda install --use-local --yes mumps
cd ..

git clone https://gitlab.kwant-project.org/kwant/conda-recipes.git
yum install -y devtoolset-2-gcc-gfortran
conda config --add channels kwant
conda build --python 3.5 conda-recipes/kwant-dev

• Building sequential MUMPS (old working recipe) with the current version of scotch on conda-forge, with:

docker run -it --rm condaforge/linux-anvil
git clone https://gitlab.kwant-project.org/basnijholt/kwant.git
cd kwant/

git clone https://github.com/basnijholt/mumps-feedstock.git
cd mumps-feedstock/
git checkout old
conda build .
conda install --use-local --yes mumps
cd ..

git clone https://gitlab.kwant-project.org/kwant/conda-recipes.git
yum install -y devtoolset-2-gcc-gfortran
conda config --add channels kwant
conda build --python 3.5 conda-recipes/kwant-dev

I can confirm that everything worked with mumps=5.0.2=blas_openblas_202:
I build with that version and uploaded it to my anaconda channel:

docker run -it --rm condaforge/linux-anvil
git clone https://gitlab.kwant-project.org/kwant/kwant.git
cd kwant/

git clone https://gitlab.kwant-project.org/kwant/conda-recipes.git
yum install -y devtoolset-2-gcc-gfortran
conda config --add channels kwant
conda config --add channels basnijholt
git reset --hard 92ad0a35b998305276e8963b7dc72cc33f5fcf3f
conda build --python 3.5 conda-recipes/kwant-dev

[basnijholt]

After hours and hours of testing the problem is completely solved by an extremely trivial change:
change the ?= to = in this line.

To see that this is indeed the case:

docker run -it --rm condaforge/linux-anvil
git clone https://gitlab.kwant-project.org/basnijholt/kwant.git
cd kwant/

git clone https://github.com/basnijholt/mumps-feedstock.git
cd mumps-feedstock/
conda build .
conda install --use-local --yes mumps
cd ..

git clone https://gitlab.kwant-project.org/kwant/conda-recipes.git
yum install -y devtoolset-2-gcc-gfortran
conda build --python 3.5 conda-recipes/kwant-dev

[basnijholt]

Reopening since MUMPS is not working in kwant.

[basnijholt]

Trying to get it to work by tweaking the build.conf:

docker run -it --rm condaforge/linux-anvil
git clone https://gitlab.kwant-project.org/kwant/kwant.git
cd kwant/

git clone https://gitlab.kwant-project.org/basnijholt/conda-recipes.git
yum install -y devtoolset-2-gcc-gfortran
conda build --python 3.5 conda-recipes/kwant-dev

[basnijholt]

Reverting to MUMPS build without MPI on the conda-forge/mumps-feedstock channel fixed the problem.
