It is not possible to compile LMMS with VST support on my x86 machine. I always get: daniel@localhost /usr/portage/media-sound/lmms $ emerge -pv lmms These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild R ] media-sound/lmms-0.4.2 USE="alsa ogg -debug -fftw -fluidsynth -jack -pulseaudio -sdl -stk (-vst)" 0 kB The latest stable wine-version is installed and of course I also set the "vst" use flag.

unmask it, try with a xcb enabled libX11 and tell us if it works first then we'll see if it can be unmasked on x86 because here it still doesn't work
(In reply to comment #1) > I guess it could be unmasked for x86? Yes, please. It would be nice if you could add at least an ~x86 keywork to the ebuild. LMMS itself works great here, but it cannot be built with VST support. (In reply to comment #2) > unmask it, try with a xcb enabled libX11 and tell us if it works first > then we'll see if it can be unmasked on x86 because here it still doesn't work What does libX11 have to do with this? In my opinion it is a problem with the ebuild itself. If I compile lmms 0.4.2 manually from the tarball, I get full VST support. I have remerged libX11 with xcb, but of course vst still does not work: localhost daniel # emerge -pv lmms These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild R ] media-sound/lmms-0.4.2 USE="alsa ogg -debug -fftw -fluidsynth -jack -pulseaudio -sdl -stk (-vst)" 0 kB Why in the world does it say "(-vst)"? And why did you set the bug status to "NEEDINFO". I can give you all the information you want :P
The problem is that loading a VST's GUI crashes LMMS (or in worst cases the whole X server) with a libxcb locking assertion failure. So please try a xcb enabled libX11, load a VST, open its GUI, and see if it crashes. Setting LIBXCB_ALLOW_SLOPPY_LOCK=1 works around this. Maybe we could add some "if has_use x11-libs/libX11 xcb, then ewarn about it" stuff, but it looks like it has been fixed in upstream trunk anyway.
PS: it's about package.use.mask, not keywords. the ~x86 keyword is a different issue. Unmask it with: echo "media-sound/lmms -vst" >> /etc/portage/profile/package.use.mask
Please note that the sloppy lock usually means that there is a (mostly trivial) bug in the code. Where the "mostly trivial" often pairs with "use of ancient internal libraries" (which was the case for Sun's Java).
(In reply to comment #5) > Unmask it with: > echo "media-sound/lmms -vst" >> /etc/portage/profile/package.use.mask Thanks a lot, that helped. After years of using Gentoo I was not aware of that file :( I am now using lmms with full vst support from the tree. I have had no issues at all after using 3 different VST plugins in lmms. Not a singe crash ;) So please, could you add an ~x86 keyword to the ebuild and remove the vst-restriction for x86 platforms? BTW: I am using a xcb enabled libX11.

In this case the issue is, that the emul-linux-x86-xlibs contain a libX11 compiled _without_ xcb support, and embedding that in an app that uses a xcb-enabled libX11 causes the sloppy locking. Tested this on OpenSUSE, they provide a xcb-enabled 32bit libX11. It works just fine there. So it should indeed be perfectly safe to unmask the vst useflag for x86, it's a amd64-only issue.
PS: Daniel, could you please open a bug report and explicitly request adding ~x86 keyword and unmasking of the vst useflag there? This one doesn't count as such.
(In reply to comment #9) > PS: Daniel, could you please open a bug report and explicitly request adding > ~x86 keyword and unmasking of the vst useflag there? OK, I've done so. See Bug 260735.
