The repo got moved to: https://github.com/NanoComp/meep.git

Also please kindly add versioned provides (provides=("meep=${pkgver}")). Thanks!

Updating libctl to the latest labctl-git, solves the build problem mentioned below.

Package seems to need recompiling following the recent hdf5/python-h5py upgrades, as attempts to write results to hdf5 fail silently. But currently the build fails with: bend-flux-ll.cpp:97:23: error: ‘make_prism’ was not declared in this scope objects[0] = make_prism( dielectric, vertices, 4, height, axis); Suspect this is an upstream issue - see https://www.mail-archive.com/meep-discuss@ab-initio.mit.edu/msg06033.html and ff. Downgrading hdf5 to 1.10.1-3 and python-h5py to 2.7.1-1 gets me back on the road.

Thanks for the help and advice; I went through recompiling everything listed by pacman -Qqm which looked remotely relevant. Something solved the issue - I am not sure what. Now removed that evil link!

ian11213, recompiling the packages is the only thing I can think of. I had the exact same issue (with python-numpy in fact) and I solved it by recompiling openblas.

I strongly suggest you try to find the library that is looking for the old libgfortran and recompile it instead of simlinking to ligbfortran.so.4

Hi, Heitzmann - thanks. Yes, I understand I am doing very bad things here. But I had already recompiled all the AUR packages I can find; that did not fix it and I urgently needed meep running. Any other hints? Otherwise I'll just do another sweep through looking for any packages I may have missed previously. Thanks for your work maintaining the package.

ian11213, that is a bad solution.

After upgrading gcc-libs (which includes libgfortran) you have to recompile any packages you compiled locally, such as any *-git packages from AUR, openBLAS, etc.

After latest package upgrades (7 May) gives Python 3 error: Traceback (most recent call last): File "/home/me/sample.py", line 1, in <module> import meep as mp File "/usr/lib/python3.6/site-packages/meep/init.py", line 8, in <module> from . import _meep ImportError: libgfortran.so.4: cannot open shared object file: No such file or directory</module></module>

Working solution by making link titled libgfortran.so.4 to libgfortran.so.5 in /usr/lib

Please add git as makedepends.
