Why need setting `LD_LIBRARY_PATH` with conda python? #42

Closed lwshang closed 6 years ago

lwshang commented 6 years ago

To have embedPy work with conda python on Linux, we have to set LD_LIBRARY_PATH. This looks like a temporary work around and may cause several issue when we using other softwares.

Why this setting is needed? Which part of embedPy request it?

I'm asking this question because I want to help solve it. embedPy may not be good enough to be used in production with this issue.

This is an issue as anaconda packages libraries which may conflict with the (system) versions loaded by q at startup (e.g. libssl or libz). There is an conda packaged version of q which doesn't require this now, if you are already using anaconda then you can install it with

conda install -c kx kdb

Got it. I've started using conda to install kdb and embedPy since kx25. It's really convenient.
