some gui's don't open in Ardour

[magnetophon]

When I compile https://github.com/magnetophon/constant-detune-chorus/archive/v0.1.2.tar.gz with faust 1 git 2016-04-27, ardour says:

suil error: Unable to open UI library /home/bart/.lv2/ConstantDetuneChorus.lv2/ConstantDetuneChorusui.so (/nix/store/p2qjdyf5z2pvj38xx1hdbmfc87pixk8b-qt-4.8.7/lib/libQtNetwork.so.4: undefined symbol: SSLv2_server_method

when I open the gui. I can edit with generic controls NP.

Can you please post the exact command/build process used to compile the dsp?

[magnetophon]

I'm doing: faust2lv2 -gui -t 99999 ConstantDetuneChorus.dsp

The plugin and its gui work fine for me, with both Ardour and Qtractor. Are you sure that you compiled the plugin with Qt4? What does faust2lv2 -h say?

[Albert Graef]

Ok, from the error message it looks like it's Qt4. But the /nix/store/p2qjdyf5z2pvj38xx1hdbmfc87pixk8b-qt-4.8.7 path looks suspicious to me. Looks like a temporary path, are you sure that the path exists and the Qt4 libraries are there?

This definitely looks like a linker issue. What kind of Linux system is this and which gcc version are you using? Also, can you please post the output of ldd ConstantDetuneChorus.lv2/ConstantDetuneChorusui.so?

Over here on Arch libQtNetwork.so.4 isn't even linked into the UI binary (it isn't really needed unless the module is built with -httpd -qrcode), but this probably depends on the gcc/binutils version.

Oops, turns out I had a bad version in ~/.lv2. Sorry for the noise!
