Description of problem: I needed to compile an old gtkmm 2.4 application under Fedora 23. Gtkmm24-devel would not install because there is no libpng-devel-1.6.19 for fc23, although the installed system libpng is 1.6.19. Perhaps this was purposeful. I "solved" the problem by force installing libpng-devel-1.6.19-1.fc22.x86_64.rpm. Compiling then crashed and burned with a series of stuff like this: In file included from /usr/include/sigc++-2.0/sigc++/functors/slot.h:7:0, from /usr/include/sigc++-2.0/sigc++/signal_base.h:27, from /usr/include/sigc++-2.0/sigc++/signal.h:8, from /usr/include/sigc++-2.0/sigc++/sigc++.h:86, from /usr/include/glibmm-2.4/glibmm/thread.h:51, from /usr/include/glibmm-2.4/glibmm.h:87, from /usr/include/gtkmm-2.4/gtkmm.h:87, from main.h:1, from main.cpp:1: /usr/include/sigc++-2.0/sigc++/adaptors/adaptor_trait.h:17:57: error: parse error in template argument list #define SIGC_WORKAROUND_OPERATOR_PARENTHESES template operator() ^ /usr/include/sigc++-2.0/sigc++/adaptors/hide.h:438:29: note: in expansion of macro ‘SIGC_WORKAROUND_OPERATOR_PARENTHESES’ { return this->functor_.SIGC_WORKAROUND_OPERATOR_PARENTHESES<type_trait_pass_t<T_arg1>> ^ /usr/include/sigc++-2.0/sigc++/adaptors/adaptor_trait.h:17:57: error: expected ‘operator’ #define SIGC_WORKAROUND_OPERATOR_PARENTHESES template operator() ^ /usr/include/sigc++-2.0/sigc++/adaptors/hide.h:438:29: note: in expansion of macro ‘SIGC_WORKAROUND_OPERATOR_PARENTHESES’ { return this->functor_.SIGC_WORKAROUND_OPERATOR_PARENTHESES<type_trait_pass_t<T_arg1>> ^ /usr/include/sigc++-2.0/sigc++/adaptors/adaptor_trait.h:17:57: error: expected ‘;’ #define SIGC_WORKAROUND_OPERATOR_PARENTHESES template operator() ^ /usr/include/sigc++-2.0/sigc++/adaptors/hide.h:438:29: note: in expansion of macro ‘SIGC_WORKAROUND_OPERATOR_PARENTHESES’ { return this->functor_.SIGC_WORKAROUND_OPERATOR_PARENTHESES<type_trait_pass_t<T_arg1>> I suppose this may be a "non-backward compatibility" issue with g++ but as far as I can tell there is only one package option for that, so I did not try an earlier one. Version-Release number of selected component (if applicable): libsigc++20-devel-2.6.1-1 How reproducible: Always. Steps to Reproduce: 1. Try to compile something using gtkmm24. 2. 3.

This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
