I'm trying to use pyswmm on fedora with python 3.6. When I install it using pip the shared object library is not install at pyswmm/lib/linux/swmm5.so. If I download the shared object library from the pyswmm github site and put it in pyswmm/lib/linux/swmm5.so, I then get the following attribute error:

swmm5.so: undefined symbol: swmm_getVersionInfo

when I run execute. I think I need to compile the swmm5 shared library on my own machine. Could I get the makefile to compile swmm5.so?

Thanks
Jim

@jmpmcmanus, pyswmm is fully supported on windows as of today. We are working on upgrading the project so that swmm is built specific for each platform automatically. The builds currently happen "offline" and in the case of Linux, we currently don't have anyone building these regularly as we make improvements to swmm. This explains why when you are calling swmm_getversioninfo it's not working (since that function is relatively new and not present in the swmm.so you downloaded).

In continuation:

I also tried ln -s libswmm5.so to pyswmm/lib/linux/swmm5.so, but got a core dump when I tried using pyswmm.

Can you share the error info?

@jmpmcmanus,

What if you try:

>>> from pyswmm import Simulation
>>>
>>> with Simulation('model.inp') as sim:
...     for ind in sim:
...         pass

@jmpmcmanus, output to the screen? or output to files?

If output to screen is what you are looking for you can print the time, for example.

>>> from pyswmm import Simulation
>>>
>>> with Simulation('model.inp') as sim:
...     for ind in sim:
...        print(sim.current_time)

You can specify a path to the rpt and out files if you want:

Simulation('model.inp', 'model.rpt', 'model.out')
