How to use MacOSX.sdk/System/Library/Frameworks/OpenGL.framework

[HealthyPear]

I am working from a conda environment where I have installed the Geant4 toolkit with OpenGL support.

I am trying to do it like this,

src = 'src'

incdir = include_directories('include')

sources = files([
  src / 'my_exe.cpp'
])

opengl_framework = dependency('appleframeworks', modules : 'OpenGL')
geant4 = dependency('Geant4', version : '>=11.1.3', modules:['Geant4::G4tools', 'Geant4::G4ptl', 'Geant4::G4analysis', 'Geant4::G4digits_hits', 'Geant4::G4error_propagation', 'Geant4::G4event', 'Geant4::G4geometry', 'Geant4::G4global', 'Geant4::G4graphics_reps', 'Geant4::G4intercoms', 'Geant4::G4interfaces', 'Geant4::G4materials', 'Geant4::G4parmodels', 'Geant4::G4particles', 'Geant4::G4persistency', 'Geant4::G4physicslists', 'Geant4::G4processes', 'Geant4::G4readout', 'Geant4::G4run', 'Geant4::G4track', 'Geant4::G4tracking', 'Geant4::G4FR', 'Geant4::G4visHepRep', 'Geant4::G4RayTracer', 'Geant4::G4Tree', 'Geant4::G4VRML', 'Geant4::G4GMocren', 'Geant4::G4vis_management', 'Geant4::G4modeling', 'Geant4::G4ToolsSG', 'Geant4::G4OpenGL', 'Geant4::G4visQt3D', 'Geant4::G4UIVisDefinitions'])

exe = executable('my_exe', src / 'my_exe.cpp', dependencies : [geant4, opengl_framework],
  install : true, include_directories : incdir)

but I get this error

clang-16: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.

so it puts the right path under -isystem instead of -framework

from the documentation it's not really clear to me how to proceed or which other solutions to try

[dcbaker]

I think you just want dependency('GL') (or maybe lowercase gl). That will add the right -Framework arguments. I’ve been meaning to overhaul how framework dependencies, but I’ll need a Mac again for that

[HealthyPear]

Thanks @dcbaker, I tried that following the docs but it didn't change the result.

I also tried something different: I compiled Geant4 without OpenGL support but with Qt support and I got the same error with the AGL framework

ld: can't map file, errno=22 file '/Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/System/Library/Frameworks/AGL.framework' for architecture x86_64

which I am calling with

agl_framework = dependency('appleframeworks', method:'extraframework', modules : 'AGL')

and it seems to work for what concerns finding it

Run-time dependency appleframeworks found: YES (agl)

[HealthyPear]

to be more precise: when I use dependency('appleframeworks', method:'extraframework', modules : 'BLA') I see the -framework BLA part in the linking step at the last place, it's just that before that the framework is called with the directly as a file, whereas it is a folder

[dcbaker]

This seems like something’s regressed. We do this -isystem thing so that compilers that don’t natively understand frameworks can still use them, and this used to work for compilers that do understand them, but it seems that’s changed.

[HealthyPear]

should we upgrade this discussion to an actual issue then?
