Don't mix headers from different versions of the library. There's no way that will lead anywhere good. > On 10/8/22 00:57, Max Nikulin wrote: > > https://github.com/libsigcplusplus/libsigcplusplus/blob/master/NEWS > > > 2.5.2 (unstable): > > > > > > * Remove useless headers: > > > sigc++/class_slot.h > > > sigc++/hide.h > > > sigc++/method_slot.h > > > sigc++/object.h > > > sigc++/object_slot.h > > > sigc++/retype.h > > > Some of these still have equivalents in sigc++/adaptors/ > > > (Kjell Ahlstedt, Murray Cumming) Bug #752560 I did a google search and came up with <https://github.com/dbus-cxx/libsigc--3.0/blob/master/ChangeLog> which says: 2015-08-13 Kjell Ahlstedt <kjell.ahlst...@bredband.net> Remove the sigc++/object.h header Because it now contains no API. See https://bugzilla.gnome.org/show_bug.cgi?id=752560#c6 So now we know what "Bug #752560" refers to. That site also claims that sigc++/object.h contains no functional code, but warns that removing it would break applications which happen to include it. >From a previous message, it appears you've already tried commenting out the #include, and you still get errors of some kind. At this point, it would seem that these errors are coming from something *other* than your deprecated header file. In short, the program you're trying to build was written to use an older version of libsigc++. You may need to do one of these things: * Update your program (gspeaker?) to use the current libsigc++ API. * Build and install an older version of libsigc++, ideally in a local directory, NOT in /usr. * Find a way to achieve your goals without using gspeaker at all.
