jasper dylib current version regressed

[jeremyhu (Jeremy Huddleston Sequoia)]

After updating jasper to 2.0.6, we see the following rev-upgrade errors:

jasper-1.900.29 had current and compat versions of 5.0.0. jasper-2.0.6 has current and compat versions of 4.0.0.

If jasper-2.0.6 is backwards compatible, it should have a compat version of 5.0.0 and a current version newer than 5.0.0. If jasper-2.0.6 is not backwards compatible, it should have a different dylib id and all dependents should be revbumped.

More fallout from switching to cmake, which doesn't appear to let you set compatibility_version independently of the soname/major version. So libjasper.4.dylib built by cmake will always have current and compat versions of 4.x.y.

​https://cmake.org/cmake/help/v3.7/prop_tgt/SOVERSION.html

I think we might just need to rev bump the dependents. :/

[dbevans (David B. Evans)]

Or revert jasper to the version version until these issues are ironed out. Quite a few ports are currently broken. The few that I currently have installed are:

GraphicsMagick
OpenSceneGraph
OpenSceneGraph-devel
dcraw
gdk-pixbuf2
gegl
gegl-0.3
gegl-devel
gimp2
gimp2-devel
gimp3-devel
gstreamer010-gst-plugins-bad
kdelibs4
kopete
libraw
netpbm
opencv
ufraw

jasper dependents: rev bump

Upstream's switch to cmake led to an apparently inadvertent change in
library versioning.

Remind me why does anybody use this idiotic broken build system?

Replying to ryandesign:

Because it has a more permissive license than the other idiotic broken build system that everyone else uses.

I see the problem with ncl build with the new lib jasper and then copying back the pre-current lib jasper

Current libjasper
