Hi,

currently src:gemmi builds gemmi and gemmi-dev. This doesn't permit to
build any software using gemmi-dev without static linking.

The proposed patch adds package libgemmi1 which contains the shared
library.

Hi Yadd,

I appreciate the idea and your patch, thanks for giving gemmi a look.
However, I am hesitant to package gemmi shared library for Debian for
now. The previous two releases had breaking API changes each. If
upstream handles this properly and bumps the soversion, then this is
fine, although having to undergo a transition twice a year is still
quite some work. However, if the upstream does not maintain ABI
stability inside the same soversion, then I would say the shared library
is not yet ready for Debian.

You have marked this bug as severity:important. Does this mean you need
gemmi's shared library for some package?

I never had the need to manually trigger the ldconfig before. The issue
might be the lack of 'Section: libs' in binary package description.

Thanks,
Andrius

Hi,

yas I'm going to package ovito which depends on it. If shared library
isn't provided, cmake automatically uses libgemmi_cpp.a which then embed
gemmi into ovito :-(

Maybe it's the issue

Hi,

I see. OK, let me apply your patch and build the shared library for
gemmi, and let's see what happens.

Best wishes,

Hi,

I looked into the shared library provided by gemmi v0.6.4 (newer
upstream release than in your patch). This version of gemmi builds the
shared library by default. However, the produced shared library does not
carry a soversion, thus according to Debian principles it is not
suitable to be packaged as public shared library, alas. Thus static
linking is the only option for now.

Best wishes,
Andrius
