#72629: gpredict port won't open
---------------------+----------------------
 Reporter:  dershow  |      Owner:  (none)
     Type:  defect   |     Status:  new
 Priority:  High     |  Milestone:
Component:  ports    |    Version:
 Keywords:           |       Port:  gpredict
---------------------+----------------------
 The gpredict port (not the actual installed application) seems to be
 broken.


 {{{
 % port outdated
 The following installed ports are outdated:
 gpredict                       2023122422-098e3768_0 <
 2024091715-098e3768_1
 }}}

 If I try to updated I get this:


 {{{
  % sudo port  -u upgrade outdated
 Error: Unable to open port: If you use this app with the gtk3 X11 backend
 you may have issues  with the background turning black and dialog windows
 crashing.

         If you have these issues the only known work-around is to switch
 gtk3 to using the Quartz backend via the commands:

         sudo port install glib2 +quartz -x11
         sudo port install libepoxy +quartz -x11
         sudo port install gtk3 +quartz -x11

         You should probably reinstall all gtk3 applications, including
 gpredict after.
 Error: Follow https://guide.macports.org/#project.tickets if you believe
 there is a bug.
 }}}

 I tried to uninstall and reinstall, but not only won't it install,


 {{{
 % sudo port install gpredict
 Error: Unable to open port gpredict: If you use this app with the gtk3 X11
 backend you may have issues  with the background turning black and dialog
 windows crashing.

         If you have these issues the only known work-around is to switch
 gtk3 to using the Quartz backend via the commands:

         sudo port install glib2 +quartz -x11
         sudo port install libepoxy +quartz -x11
         sudo port install gtk3 +quartz -x11

         You should probably reinstall all gtk3 applications, including
 gpredict after.
 }}}



 it won't even give info


 {{{
 % port info gpredict
 Error: Unable to open port: If you use this app with the gtk3 X11 backend
 you may have issues  with the background turning black and dialog windows
 crashing.

         If you have these issues the only known work-around is to switch
 gtk3 to using the Quartz backend via the commands:

         sudo port install glib2 +quartz -x11
         sudo port install libepoxy +quartz -x11
         sudo port install gtk3 +quartz -x11

         You should probably reinstall all gtk3 applications, including
 gpredict after.
 }}}


 So, this seems like either a bug in the port file, or a bug in Macports
 itself, since it is not possible to even get information about the port.
 Does that mean that the port has been deprecated?

 I have seen this, which is related:
