mac os x + netcdf + pykst

Fellow kst-ers,

I am having a bit of trouble installing/configuring kst on os x, and I hope you can provide some guidance.

My goal is to use kst to read netCDF files and take advantage of the python scripting using pykst. I’m on a macbook pro running os x 10.10.5, with python 2.7 run from anaconda package with Qt5 installed. Here is what i’ve tried so far:
- Installed pykst manually, as per the instructions from - this appears to run in an ipython.
- Installed the kst v2.0.8 .dmg binary, and ran the first scripting example (the sine wave) from the docs, which, after some simple modifications to, worked without issue. However, there appears to be no support for netcdf files (i.e. no netcdf reader shown in Data Sources in Help - Debug Dialog)
- Installed the v2.0.7 .dmg binary (after uninstalling v2.0.8). This version appears to contain support for netcdf, with the reader present in Data Sources, recognises netcdf format (but config is greyed out) and i’m able to open and view example files. However, when I run the python example script, after a few noSuchFun() calls, kst crashes and closes.
- Attempted to install from source, but failed. I downloaded the git repo, ran cmake, and got an error after Qt5 was found, which claimed that Qt4 was required.

Of course, the other option would be to use the dirfile format. However, the application will require writing data from 3000 sensors at a rate of ~500 Hz, and its my understanding that with dirfiles, each sensor would require its own file, and i’m not sure if 3000 open files at once is a good idea (i’m happy to switch if that assumption isn’t valid).

Any help would be appreciated. Let me know if there is any other information that would be helpful.

Thanks, Pete
