g2clib static lib file name change

[Jos de Kloe]

Hi,

I just build a new version of g2clib (upgraded from 1.4.0 to 1.6.0), and
with this change this static library for grib file handling changes name:
old: libgrib2c.a
new: libg2c_v1.6.0.a

I dont know of a packaging guideline that tells me to announce this, but
to prevent surprises for dependent packages I thought I'd mention it.

Best regards,

Jos

Well, are you aware of any src.rpm that needs this library as build
requirement? If so, better inform the packager directly, because the next
(re)build of that package will fail. If not other packages in the distribution
use this lib, there may be private users of the Fedora package, but it's
uncertain whether they can be reached via devel@ list.

Packaging guidelines don't cover changes like that, but Update guidelines
may: https://fedoraproject.org/wiki/Category:Package_Maintainers

Hi, thanks for your remark.

I am aware of one single other package that uses this lib, for which I
am the maintainer myself.

The updates policy for rawhide says:

Actually I don't know how to
find out if there are others. I could not
find an easy tool/method in the collection of fedora packaging
tools/websites to do a query for other packages that have a BR on this
library.

Thanks Volker,

so the affected packages are:
   gdal, grads, ncl, pygrib, wgrib2

I will fix pygrib myself.
Orion Poplawski knows about the change and already looked at gdal.
He also is main contact for ncl and wgrib2.

So only grads remains. I filed a bugzilla entry to warn the maintainers
about this change.
