Dear Chris and meep-discussion:
I have run into a seemingly strange problem with h5topng, the program in
h5utils that converts h5 files to png. While working on a python
tutorial file in the parallel python meep environment (pmp) h5topng
works with no problem. However, when working with the identical python
file in the serial python meep environment (mp), I trigger a core dump
when invoking h5topng. The error message claims that the headers
version is 1.10.1 while the library version is 1.10.2., and the fact
that the versions don't match triggers the core dump.

(mp_test) john@Samba:~/pymeep/examples/myexamples$ h5topng -t 229 -R -Zc
dkbluered -a yarg -A right_angle_waveguide-eps-000000.00.h5
right_angle_waveguide-ez.h5
Warning! ***HDF5 library version mismatched error***
The HDF5 header files used to compile this application do not match
the version used by the HDF5 library to which this application is linked.
Data corruption or segmentation faults may occur if the application
continues.
This can happen when an application was compiled by one version of HDF5 but
linked with a different version of static or shared HDF5 library.
You should recompile the application or check your shared library related
settings such as 'LD_LIBRARY_PATH'.
You can, at your own risk, disable this warning by setting the environment
variable 'HDF5_DISABLE_VERSION_CHECK' to a value of '1'.
Setting it to 2 or higher will suppress the warning messages totally.
Headers are 1.10.1, library is 1.10.2
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
The LD_LIBRARY_PATH is not set and "which h5topng" shows that the
command points to the appropriate path for ~/miniconda/envs/mp and
~/miniconda/envs/pmp.
I don't understand why I'm getting the core dump in the mp environment
(and in the mp_test environment) but not in the pmp environment.
Any suggestions would be greatly appreciated.
Best regards,
John
