[Debian-med-packaging] [wrar at debian.org: Re: Dynamic library inside Python module python-pysam not found]

[Andreas Tille]

Hi Afif,

may be this mail contains some helpful hint since it seems that the lib
libchtslib.so simly should not be created at all.  I tried my luck with
setting 

   HTSLIB_MODE = "external"

but this did not lead to any sensible result.

Please also note that setup.py says

   The current version wraps htslib-1.3.1, samtools-1.3.1 and bcftools-1.3.1.
                                    ^^^^^

so I have no idea where you've git the information from that 1.3.2 is
supported.

I'll leave this now for others who might have a better clue than me.

Kind regards

       Andreas.

First you need to find out if that lib is some useful code or a copy of
libhts that for some reason got built and used even with
HTSLIB_MODE=external.
If it should still be built, then it's either a shared lib and then it
doesn't belong in dist-packages, or a python module and then it shouldn't
ne linked against.
