Jan 31 P.R. ->

1) Relaxed security controls to be able to download and install software

2) Installed generic software:
Chrome browser
Notepad++
Paraview
WinSCP

3) Install software for Elmer build under D:/
msys2-x86_64-20190524.exe 

4) Update msys2 core components (if you have not done it yet):
pacman -Sy
pacman --needed -S bash pacman pacman-mirrors msys2-runtime
You must exit out from MSYS2-shell, restart MSYS2-shell, then run below command, to complete rest of other components update:
pacman -Su

5) in msys install
pacman -S git
pacman -S make mingw-w64-x86_64-cmake
pacman -S mingw-w64-x86_64-gcc-fortran (includes gcc)
pacman -S mingw-w64-x86_64-openblas
pacman -S mingw-w64-x86_64-nsis
pacman -S mingw-w64-x86_64-qt5
pacman -S mingw-w64-x86_64-qwt-qt5 (includes qt5)
pacman -S mingw-w64-x86_64-msmpi
pacman -S mingw-w64-x86_64-oce
pacman -S mingw-w64-x86_64-vtk
pacman -S mingw-w64-x86_64-lapack (needed by MUMPS)
pacman -S emacs

6) get elmerfem under D:/ElmerBuild using msys & git 
git clone https://github.com/ElmerCSC/elmerfem.git
git submodule sync
git submodule update --init

7) 1st trial to compile
D:\ElmerBuilder
source build_nightly.sh (64bit msys2)
- compiles with Qt5 & MPI out of the box
- does not compile with QWT & Zoltan etc. 
- ElmerGUItester & logger does not compile
however:
- Qt5 and MPI setup not ok on installers
+ gfortran seems ok

8) Additional libraries
D:\Libraries
Mumps:
https://github.com/scivision/mumps.git
- requires lapack
- does not find MPI 

Hypre
- Not for windows


8) when succefull Elmer needs the following paths set:
export ELMER_HOME=/d/ElmerBuilder/Elmer8
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ELMER_HOME/lib
export PATH=$PATH:$ELMER_HOME/bin


9) Signing
pacman -S mingw-w64-x86_64-openssl
