VeSTige causes LMMS to freeze.

Ahoy

I'm running an x86_64 system and have installed LMMS and tried to load Synth1, a VST that should work flawlessly under LMMS. It shows a little message box saying "Please wait while loading VST-plugin" until LMMS is killed.
I have tried installing lmms-vst (which is deprecated) from the AUR, however the compilation fails and prints:

[ 42%] Building CXX object CMakeFiles/lmms.dir/src/core/AutomatableModel.o

I have also tried building lmms from git with no success (startup fails:

Any help or guidance would be much appreciated, thanks

Re: VeSTige causes LMMS to freeze.

Don't know where you got your VST but try using VST's from this list...

Synth1 should always work. I checked a few other (Fnequalizer, Subfreak, VSTSpeek) and they all also freeze the window.

Re: VeSTige causes LMMS to freeze.

I'm having the same issue.

See the relevant GitHub Issue Report Supposedly someone named Narfinger has come up with a fix, but it breaks another portion of the code:

Although #2304 potentially fixes this issue, it was never merged into our source code due to it breaking backwards compatibility for the old VST behavior

I tried his Narfinger's "vestige-fix" branch and was able to get it to compile and run, but still not able to get it to load a VST file (Synth1 32bit a.k.a. their "standard" for VST testing). You might give it a shot though, you may have better luck than me.
