convergence never achieved about mpb HOT 5 CLOSED

I am under Arch Linux, and installing via AUR (https://aur.archlinux.org/packages/mpb-git/

from mpb.

Hi. I'm not very familiar with Arch or the AUR, but I just confirmed that the tutorial example you listed works correctly when built from the HEAD of the master branch. I would suggest notifying the maintainer of the mpb-git package on AUR of this issue. Building from source can reliably get you a working installation, though it is a little more work.

Thanks for suggestion.
I tested building locally with

git clone git://github.com/stevengj/mpb
cd mpb
sh autogen.sh
make

This gives the same result. Not sure if that's because my building environment. I have gcc 8.1.0 as compiler. I also tried gcc 6.4.1 and the iteration details are a little different but it also doesn't considered converge in the software. Any other compiling environment I should check? Thank you!

I was able to run the example successfully in an Arch docker container by building as follows.

pacman -Syu
pacman -S base-devel
pacman -S gcc-gfortran
pacman -S blas
pacman -S lapack
pacman -S hdf5
pacman -S fftw
pacman -S guile
pacman -S git

git clone https://github.com/stevengj/libctl
cd libctl
sh autogen.sh --enable-shared --prefix=$HOME/local
make && make install
cd ..

git clone https://github.com/stevengj/mpb
cd mpb
sh autogen.sh \
    CPPFLAGS="-I${HOME}/local/include" \ 
    CFLAGS=${CPPFLAGS} \
    LDFLAGS="-L${HOME}/local/lib -L/usr/lib64" \
    GEN_CTL_IO="${HOME}/local/bin/gen-ctl-io" \
    --enable-shared \
    --prefix=$HOME/local \
    --with-libctl=$HOME/local/share/libctl

make && make install

cd mpb
./mpb ../example/tutorial.ctl

Thank you so much for helping me on this. I checked every package you installed and it seems the problem is fftw, where in AUR it make dependence of fftw-mpi. I replaced fftw-mpi and hdf5-mpi with original non-mpi version and it works.
