Describe the bug

When running make install, I get a fatal error: [ 98%] Built target darkroom In file included from /bausite/git/darktable/build_dark/lib64/darktable/plugins/introspection_lens.cc:175: /bausite/git/darktable/src/iop/lens.cc: In function ‘lfModifier _get_modifier(int, int, int, const dt_iop_lens_data_t, int, gboolean)’: /bausite/git/darktable/src/iop/lens.cc:993:46: error: no matching function for call to ‘lfModifier::lfModifier(lfLens const&, const float&, const int&, const int&)’ 993 | mod = new lfModifier(d->lens, d->crop, w, h); | ^ compilation terminated due to -Wfatal-errors. make[2]: [lib64/darktable/plugins/CMakeFiles/lens.dir/build.make:85: lib64/darktable/plugins/CMakeFiles/lens.dir/introspection_lens.cc.o] Error 1 make[1]: [CMakeFiles/Makefile2:8312: lib64/darktable/plugins/CMakeFiles/lens.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs....

Where did you obtain darktable from?

self compiled

darktable version

I cannot give you the version as this is from git master just pulled tonight.

What OS are you using?

Linux

What is the version of your OS?

slackware-current

Describe your system?

It's a linux box I put together from parts. 64 gb of ram,

Are you using OpenCL GPU in darktable?

Yes

If yes, what is the GPU card and driver?

Card: VGA compatible controller: NVIDIA Corporation GA104 [GeForce RTX 3060 Ti Lite Hash Rate] Driver: NVIDIA-Linux-x86_64-550.135

Please provide additional context if applicable. You can attach files too, but might need to rename to .txt or .zip

This is a build issue. DT usually builds and works just right :-)

Which version of lensfun do you have installed? There's a 0.3.95 floating around (which some distros include simply because it has a higher version number) that is really a pre-alpha version having incompatible API changes with no practical way to determine automatically at compile-time which API to use.... You need 0.3.3 or 0.3.4. Current master builds just fine for me with 0.3.3.

OK, that was it. I was using lensfun-3.99 and that was a no-go, as you just told me ;-)

I'm now running lensfun-3.4 and DT builds just fine.

Thanks for the help.
