oasys1-srwlib's Issues

Linux library built against a too recent GLIBC version

Ciao @lucarebuffi

I ran into trouble upgrading OASYS to version 1.1 with the OASYS1-SRW package. After installing the corresponding add-on, I get the following errors in the console:

Could not import 'orangecontrib.srw.widgets.tools.ow_srw_wavefront_file_reader'.
Traceback (most recent call last):
  File "/dls_sw/apps/python/anaconda/1.7.0/64/envs/oasys1_1/lib/python3.6/site-packages/orangecanvas/registry/discovery.py", line 262, in iter_widget_descriptions

    import srwlpy as srwl
ImportError: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /dls_sw/apps/python/anaconda/1.7.0/64/envs/oasys1_1/lib/python3.6/site-packages/srwlpy.so)

This is because at Diamond we are running RHEL 6, which is rather old, and therefore cannot run any compiled libraries that have been linked against a more modern version of GLIBC.

I am not sure what the best course of action is though:

  1. Recompiling srwlpy.so on a sufficiently old system and making a new release
  2. Integrate compilation of srwlpy from source into the setup.py file as an extension. This would also make shipping the platform dependent libraries redundant and remove the need for copying the correct binary module at compile-time. The sourcecode does not appear to be part of this repository though 😢

Best regards,

Tom
