Dear Fenics community,
I’m currently trying to build Dolfin-x on Ubuntu 18.04 LTS with gcc 7.5.0 and mpich-3.3.2.
What I did:
installed mpi4py, latest PETsc, latest Eigen3 (form today):
`pip3 install mpi4py --no-cache-dir`
`git clone https://gitlab.com/petsc/petsc.git petsc_dev`
`./configure --download-fblaslapack --download-blacs --download-metis --download-parmetis --download-parms --download-ptscotch --download-scotch --download-suitesparse --download-scalapack --download-mumps --download-superlu --download-superlu_dist --download-hypre --download-sundials --download-petsc4py`
(making PETSc and installing as proposed)
`sudo apt install libeigen3-dev`
Thereafter, the following commands:
```
git clone https://bitbucket.org/fenics-project/fiat
git clone https://bitbucket.org/fenics-project/dijitso
git clone https://bitbucket.org/fenics-project/ufl
git clone https://github.com/FEniCS/ffcx
git clone https://github.com/FEniCS/dolfinx
git clone https://bitbucket.org/fenics-project/mshr
cd fiat && pip3 -v install --no-deps . && cd ..
cd dijitso && pip3 -v install --no-deps . && cd ..
cd ufl && pip3 -v install --no-deps . && cd ..
cd ffcx && pip3 -v install --no-deps . && cd ..
mkdir -p dolfinx/cpp/build && cd dolfinx/cpp/build && cmake .. && sudo make -j 6 install && cd ../..
cd python && pip3 install . --no-deps
mkdir -p mshr/build && cd mshr/build && cmake .. && sudo make -j 6 install && cd ../..
cd mshr/python && pip3 -v install --no-deps . && cd ../..
```
The command for building Dolfin-x (first sudo make -j 6 install) fails:

**(…)** plus a bunch of multiple further errors.
Tried latest Eigen3 release version, too, no success.
Ran through the process multiple times with complete removal and re-installation of all dependent packages, no success.
Does Dolfin-x only build against older, specific PETSc / Eigen3 versions?
Thanks for your help!
Best wishes,
Marc
P.S.: Installing the Fenics development version (so ffc and dolfin instead of the -x variants) works well.

The installation script used for dolfinx can be Found in this [Dockerfile](https://github.com/FEniCS/dolfinx/blob/master/docker/Dockerfile). Here versions of most of the dependencies are specified.
