Comment 1 Richard Shaw 2015-02-17 14:31:26 UTC 
I can confirm I get the same results on F20... Not sure what's going on. 

It seems to be in there somewhere:
$ grep  "struct_Rot_get_position" /usr/lib/python2.7/site-packages/_Hamlib.so 
Binary file /usr/lib/python2.7/site-packages/_Hamlib.so matches
Comment 2 Jacek Radzikowski 2015-04-30 00:47:07 UTC 
I would like to ping on this bug. Is the package still maintained?
Comment 3 Richard Shaw 2015-04-30 03:09:16 UTC 
Upstream (if you can call it that, it's basically one guy and some frequent contributors) is active, but most of the effort it going into Hamlib3. I'll see if I can get him to take a look.
Comment 4 Richard Shaw 2015-07-02 02:08:30 UTC 
Upstream has not been able to duplicate the problem, it seems to be specific to Fedora and I'm out of ideas.
Comment 5 Michael Schwendt 2015-07-19 13:10:13 UTC 
Can you comment on the "implicit declaration of function" warnings in the build.log?

No, that file is generated by swig... Looking at the first one:

$ grep -r Rig_get_mode .
./bindings/Hamlib.py:    def get_mode(self, *args): return _Hamlib.Rig_get_mode(self, *args)
./bindings/rig.swg:void Rig_get_mode(Rig *self, unsigned *mode, int *width, vfo_t vfo)

I don't know swig at all but that looks like a declaration?
Comment 7 Matthieu Gautier 2015-07-19 16:58:12 UTC 
It seems that is a problem with swig package itself.

See bug 1180257
Comment 8 Jitka Plesnikova 2015-09-21 07:00:55 UTC 
I removed the swig's patch which caused the issue from all Fedoras.

I checked that hamlib rebuilt against the latest swig solved the bug.
Comment 9 Richard Shaw 2015-09-22 02:09:23 UTC 
Fantastic! When you submit the updates can you add this bug so it closes when they go to stable?
Comment 10 Jitka Plesnikova 2015-09-22 06:53:56 UTC 
hamlib has to be rebuilt against new swig to solve the issue. It is necessary regenerated the invalid code in hamlib.

I'll create the overrides and rebuild hamlib for all Fedoras.

Comment 14 Richard Shaw 2015-09-22 12:59:05 UTC 
You were too fast for me! I just updated to hamlib 3.0 and in the process was fixing the binding package names (i.e. hamlib-python -> python-hamlib) but missed updating a couple of "Requires:".

There's supposed to be 3.0.1 releasing soon so I may just wait, it only affects the devel package.
