kristall -v option doesn't have a version when built outside a git repo

[charles2910]

Hi,

while building kristall for Debian sergiodj noticed an error:

--8<---------------cut here---------------start------------->8---
make[2]: Entering directory '/<<PKGBUILDDIR>>/build'
/usr/lib/qt5/bin/uic ../src/browsertab.ui -o ui_browsertab.h
/bin/sh: 1: git: not found
/bin/sh: 1: git: not found
--8<---------------cut here---------------end--------------->8---

This happens because we don't build from the git repo, but from the downloaded tarball. So the following command from src/kristall.pro fails.

DEFINES += KRISTALL_VERSION="\"$(shell cd $$PWD; git describe --tags)\""

And the built application doesn't get a proper version when kristall -v is invoked:

# xvfb-run kristall -v
new locale is "en" "American English"
kristall

We (sergiodj and I) came up with a solution to the problem - I'll attach below and will be very happy to open a PR. But I think it's very specific so you might not want it merged - it keeps working when in a git repo though.

TLDR we're exporting KRISTALL_VERSION to the build environment so the qmake variable is not empty in our case.

I tried applying the patch in d88dd7bfd107dc8c22ae9b91a3b2a06bc7afe815, should be good now

Thanks!

And version 0.4 will be in Debian next stable release (12 - Bookworm, due around July) and also in Ubuntu 23.04, so people will be able to just apt install kristall!

That's pretty cool. I hope i can spend some time on Kristall the next days, so i can finally tack a 1.0 to the program and officially go into "maintainence" mode
