litemap: astLib - fits import issue #18

Closed ajvanengelen closed 6 years ago

ajvanengelen commented 6 years ago

I'm posting this issue on behalf of Connor Sheere, a student working with me, Joel M, and Renee H. This is apparently an issue with the astWCS package and I'm not sure whether this is related to the pyFITS / astropi.io.fits switchover, it seems to be a separate thing

Is astLib.astWCS one of the formal requirements for this package?

astLib version is 0.10.2

I have seen this error before, but in a different context that is unrelated to astLib.

ImportError: /home/csheere/.local/lib/python2.7/site-packages/PyWCSTools/_wcs.so: undefined symbol: __intel_sse2_strcpy

I think the error message above is indicating that something went wrong with astWCS compilation. I will check by trying to import astWCS directly, and check whether it gives the same error message.

I think this happens if you mix compilers. Maybe reinstall astLib after making sure you only have gcc loaded?

cgrays commented 6 years ago

Right, sorry. This worked. Thanks!
