[PyQt] pyqtdeploy, Ubuntu and dynamically loading modules...

[Ilya Kulakov]

Maybe there was a missing flag when main executable (with python interpreter) was compiled?

The error suggests that PyExc_SystemError is hidden from numpy's extension library. Ensure that the `-export-dynamic` was used by the linker.

I have successfully got my application to build, but when I come to run it and load modules dynamically I run into the following error:

Google seems to think that it may be because numpy was built with/for the (static?) system Python and this maybe some kind of issue (I actually installed it via pip). If this is the case, how do I go about rebuilding it from source as the deployed python is a library, not an exe?
