Comment 8 John Bowler 2018-11-09 19:00:36 UTC

But it seems to have happened a very long time ago, perhaps the obsolete macro has only just been removed.
Comment 9 John Bowler 2018-11-09 19:17:25 UTC
A number of deprecated things were removed and even if stuff is done to deal with these qtav builds still report use of deprecated functions.  This doesn't cause the build to fail buy I had to add -fpermissive to allow assignment of a (now?) const function pointer result to a non-const.  In then end changing CPPFLAGS as follows is sufficient:


That is from an 'env' file referened for qtav by package.env  The actual patch required will be somewhat more extensive but that at least gets it to recompile.
Comment 10 Craig Andrews gentoo-dev 2018-11-27 15:58:40 UTC
This issue has a thread on the Gentoo Forums at
Comment 11 John Bowler 2018-11-27 16:11:51 UTC
Could someone point out on that thread that Comment 9 *is* a fix; a patch isn't really required.

(I can't post to forums because my "e-mail address is already registered to a user", (duh!)
