Created attachment 92228 [details, diff] gnubg-0.14.3.ebuild.diff Here's a diff against the current version of gnubg-0.14.3 as discussed yesterday on irc with SpanKY and Mr. Bones. In our discussion there was an allusion to removing the gnuconfig_update statement, as the games eclass was doing this. It looks to me that this used to be the case but not anymore, or am I just being shortsighted as usual ? Please tell me if you'd like me to commit this myself. This bug is getting old, so I'm even ready to add my name to the metadata if that's the price to pay to get it in portage... ;o) Denis.
The reason the bug has been open for so long is because it doesn't fail for me and I haven't heard an explaination why it fails. I don't have a problem with the patch per se, I just don't like patching stuff when it's not obvious why the patch is needed. If you can explain what exactly is broken so I can reproduce the problem here, that'd be great.

If you don't, you can't have the issue, as you need both these USE flags enabled to make use of FTGL. I'm really not good at C++, but here's what I understand. A 'MyOutlineFont' class is defined, based on FTGLOutlineFont, in order to avoid using FTGLOutlineFont::Render and speed-up rendering. This fails at link time because the new class can't obviously access FTGLOutlineFont::MakeGlyph which is a private virtual. I suppose this used to work with older versions of FTGL. gnubg-0.14.3 is an old thing, and 3D rendering has certainly made a lot of progress since it was released. Even my not so recent Athlon XP 1600+ with 256 MB of RAM and a Geforce 3 Ti 200 has no issue rendering gnubg in 3D with the proposed patch (not that I like gnubg in 3D, though). This makes the trick of shunting FTGLOutlineFont::Render less necessary nowadays. And for those who still have machines old enough to suffer from rendering slowdowns in 3D, they can either build without opengl and/or simply not use the 3D boards since they are, thank Zeus, not mandatory. Denis.
It builds fine for me with: USE="X args esd gdbm gtk opengl python readline nls" ebuild ./gnubg-0.14.3.ebuild clean install for both versions of ftgl in portage.

I can confirm the whole thing is due to FTGL being compiled with -fvisibility-inline-hidden. Note that gnubg doesn't care being built with it or not (which seems logical). Now the question is, since -fvisibility-inline-hidden is on the "you're on your own" flag list (at least for some devs), is it worth opening a new bug for FTGL or not ? Denis.
I added strip-flags to the latest ftgl ebuild. Can you verify that it fixes things up for you please?
(In reply to comment #8) > I added strip-flags to the latest ftgl ebuild. Can you verify that it fixes > things up for you please? It does, thanks a lot. Denis.
great, thanks for tracking this down.
This update also fixes the amd64 arch "recompile with -fPIC" error when building anything that depends on FTGL.
