[Linux] Compile error

[KottV]

Hi, I'm trying to build your plugins but get this error:

In file included from /home/kv/src/audio/regrader/src/vstentry.cpp:24:
/home/kv/src/audio/regrader/src/ui/controller.h:41:1: error: expected class-name before ‘{’ token

/home/kv/src/audio/regrader/src/ui/controller.h:77:9: error: ‘IController’ does not name a type; did you mean ‘EditController’?

      |         ^~~~~~~~~~~
      |         EditController

does it means missing includes?

[igorski]

Hi there, IController is declared by the Steinberg SDK. Did you also compile the Steinberg SDK and provide its path to cmake (using -DVST3_SDK_ROOT=/path/to/sdk) as per the build instructions ?

[KottV]

yes, and SDK examples are built I can build other vst3 plugins too

I guess that is related to using VSTGUI namespace (I'm not good in c++)

[igorski]

Just for clarity: which SDK version are you using and what is your Linux distribution?

VSTGUI should be provided through the build of Steinbergs SDK, though it looks like you are already in the compilation phase (cmake would have let you know upfront if it couldn't find the required shared libraries upfront)

[KottV]

latest from git vstsdk3612_03_12_2018_build_67-4-g0908f47 openSUSE tumbleweed gcc 9.2.1 examples from SDk and other plugins (https://github.com/ryukau/VSTPlugins for example) compiles

[igorski]

Perhaps the issue is the SDK version as Regrader was built against 3.6.9. Will investigate in a VM

[KottV]

AFAIK, 3.6.9 has broken vstgui on Linux, thus I'm not so wish to try with that old version. Even last version has one issue for me. If you run into not found xkbcommon headers, add it's path into vstgui4/vstgui/lib/CMakeFiles/vstgui.dir/flags.make after configuring with cmake (it needs a better bugfix, yes)

[igorski]

There's always something with these "minor version" changes :)

I'll have a look with 3.6.12, see if it has breaking changes for the project and take it from there.

[KottV]

If I can make some assistance - please tell)

[igorski]

Hi, I am upgrading the project to use the latest Steinberg SDK 3.6.14 and hope to tackle the Linux issues as well. Can you checkout branch 3614 and verify whether this works for you?

[KottV]

Hi!

It compiles, thanks! But refuses to load in host:

Plugin failed to load, error was: Failed to get plugin description

[igorski]

Hi @KottV

sorry for the delay :) I have created a new branch 370 which uses Steinbergs latest SDK 3.7.0 I have managed to build it successfully in an Ubuntu VM where the plugin appears in the editorhost and passes the validator (both supplied by the SDK). Using Bitwig Studio as a DAW I can use the plugin (though opening the GUI has it appear black...).

Can you confirm whether the update build script is working for you as well (and maybe if you have more luck in your DAW) ?

[KottV]

It works in Carla, Reaper and JUCE-hosts!

just need to comment/remove this line: https://github.com/igorski/regrader/blob/a74f264e0759cd8918e4d3781b005d95a8010189/CMakeLists.txt#L27

[igorski]

Thank you so much for verifying! Glad to hear the positive results!

Good thing you mentioned that line that was local to my test env, will remove it and clean up the make file further more to have less duplicate code in between the platforms prior to merging.

Thanks again for your help!

[KottV]

Many thanks to You. Maybe other your plugins will have updates too:)
