Unable to build on Linux (debian stable)

[dromer]

The build instructions for cmake seem to be incorrect:

clap-plugins$ cmake --preset ninja-system
CMake Error: The source directory "/home/dreamer/Sources/_audio/_free-audio/clap-plugins/ninja-system" does not exist.

When I try the build script using vcpkg it also fails:

Maybe your version of cmake is a bit old?

[ghost]

@dromer what distro are you using?

[abique]

Archlinux: cmake version 3.23.2

[dromer]

Debian stable: cmake version 3.18.4

[ghost]

@abique My cmake verison is 3.22.2 (Fedora 36), which is like, one minor version older and I am able to build properly. I think @abique is maintaining the repo - it would be better to use a distro that isn't bleeding-edge. Maybe that will prevent problems for users who have stable or older Linux distros?

Or @dromer , another fix would be to build cmake manually by yourself. That should do the job too.

[abique]

Maybe you can download a build from the github actions? https://github.com/free-audio/clap-plugins/actions/runs/2231777715

[abique]

Ah it could be that it requires a glibc that is too recent for your system?

[dromer]

My whole point was to do a build on a stable distro. If it builds and runs on debian it'll build and run pretty much everywhere.

I updated to 3.24.2 from bullseye-backports .. now it gets stuck on qt6 dependencies:

-- Could NOT find Qt6Qml (missing: Qt6Qml_DIR)
-- Could NOT find Qt6Quick (missing: Qt6Quick_DIR)
CMake Error at CMakeLists.txt:15 (find_package):
  Found package configuration file:

    /usr/lib/x86_64-linux-gnu/cmake/Qt6/Qt6Config.cmake

  but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
  FOUND.  Reason given by package:

  Failed to find Qt component "Qml".

  Expected Config file at
  "/usr/lib/x86_64-linux-gnu/cmake/Qt6Qml/Qt6QmlConfig.cmake" does NOT exist

  Failed to find Qt component "Quick".

  Expected Config file at
  "/usr/lib/x86_64-linux-gnu/cmake/Qt6Quick/Qt6QuickConfig.cmake" does NOT
  exist

Also tried with vcpkg which also fails on qt: error: building qtbase:x64-linux-cp failed with: BUILD_FAILED

ERROR: Feature "xcb": Forcing to "ON" breaks its condition:
    QT_FEATURE_thread AND TARGET XCB::XCB AND TEST_xcb_syslibs AND QT_FEATURE_xkbcommon_x11

Ok, I needed package qt6-declarative-dev for this.

Trying to load these into bitwig none of them have a UI (also CLAP SVF crashes everything).

[edit: additional requirements for debian: qml6-module-qtqml-workerscript qml6-module-qtquick qml6-module-qtquick-controls qml6-module-qtquick-layouts qml6-module-qtquick-templates
