Portage ebuild use the cmake build system. When merging fluidsynth with it, I get the same error as described here.

If I change into ${S} and run configure and make, it success.

The autotools stuffs are marked as obsoletes. On the other hand, the cmake stuffs are marked as experimental. Maybe a good move, as it succeed to compile and install fluidsynth, would be that the ebuild use the autotools stuffs.

no plans in moving backwards with something as simple as missing -pthread and gnome/gtk+/glib specific -D.*DEPRECATED flags that need to be patched out from the build system

(that was an educated guess based on the warnings/errors posted here)

[Comment 6 Samuli Suominen (RETIRED) 2012-11-23 03:56:01 UTC]

added append-flags -pthread to the ebuild, no sign of gnome specific DEPRECATED flags, might be inherited from the system
