Description Mohan Boddu 2018-07-20 21:37:06 UTC 
zbar failed to build from source in Fedora rawhide

https://koji.fedoraproject.org/koji/taskinfo?taskID=28241152


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_29_Mass_Rebuild
Please fix zbar at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
zbar will be orphaned. Before branching of Fedora 30,
zbar will be retired, if it still fails to build.

Comment 4 Mauro Carvalho Chehab 2018-08-07 20:29:32 UTC 
The bug is actually at the pygobject-codegen-2.0 package. It contains a shell script with the following content:

   #!/bin/sh

   prefix=/usr
   datarootdir=${prefix}/share
   datadir=/usr/share
   codegendir=${datadir}/pygobject/2.0/codegen

   PYTHONPATH=$codegendir
   export PYTHONPATH

   exec /usr/bin/python $codegendir/codegen.py "$@"

Well, after python2 changes, the last line of the script won't do the right thing. That line should be changed to:

   exec /usr/bin/python2 $codegendir/codegen.py "$@"

(or to use /usr/bin/env python2)

As I don't maintain the above package, for now I added a logic that will do:
env $(PYGTK_CODEGEN) |sed s,python,python2, > ./codegen.sh

and then it runs the local script. That should fix the Zbar issue. Yet, the proper fix would be for the pygobject-codegen-2.0 to replace the python call directly there.

Comment 7 Hans de Goede 2018-08-09 11:31:36 UTC 
This is fixed in pygobject2-2.28.7-4.fc29 and I've done a new zbar build zbar-0.20.1-3.fc29 which drops the hack to work around this, closing.
