 |

Hello! I've been trying to compile SDRAngel from pentoo overlay, but it's complaining about OpenCV. Here is the portage output:
| Code: |
# emerge -av sdrangel --autounmask --autounmask-write
These are the packages that would be merged, in order:
Calculating dependencies... done!
Dependency resolution took 1.31 s (backtrack: 0/20).
!!! The ebuild selected to satisfy "media-libs/opencv" has unmet requirements.
- media-libs/opencv-4.8.1-r1::gentoo USE="eigen features2d ffmpeg gtk3 jpeg opengl openmp png python webp -contrib (-contribcvv) -contribdnn -contribfreetype (-contribhdf) (-contribovis) (-contribsfm) (-contribxfeatures2d) (-cuda) (-cudnn) -debug -dnnsamples -examples -gdal (-gflags) (-glog) -gphoto2 -gstreamer -ieee1394 -java -jpeg2k -lapack -non-free -opencl -opencvapps -openexr -qt5 -qt6 -tbb (-tesseract) -testprograms -tiff -v4l -vaapi (-vtk) -xine" ABI_X86="(64) -32 (-x32)" CPU_FLAGS_X86="sse sse2 -avx -avx2 -avx512f -f16c -fma3 -popcnt -sse3 -sse4_1 -sse4_2 -ssse3" PYTHON_TARGETS="python3_11 -python3_10 (-python3_12)" VIDEO_CARDS="-intel"
The following REQUIRED_USE flag constraints are unsatisfied:
opengl? ( any-of ( qt5 qt6 ) )
The above constraints are a subset of the following complete expression:

I've been struggling with the opengl? ( any-of ( qt5 qt6 ) ). As I understand, this contraints are from OpenCV, not SDRAngel, right?
If so, why can't I compile OpenCV with opengl + gtk3 flags? Is this a bug? |

Actually I just noticed SDRAngel is built upon QT5. So, just for information, that OpenCV contraint (opengl? ( any-of ( qt5 qt6 ) )) is being added by SDRAngel? How could I tell, lets say, in a future @world upgrade, what package sets those use flag contraints?

The message says that if you want to install opencv, a dependency of net-wireless/sdrangel, with opengl support you can only do it with qt5 or qt6 enabled as well.
If you don't want that you can disable opengl use flag for the package with /etc/portage/package.use file.

I need a GUI. Guess I'll be looking for alternatives. Gqrx just adds too many python dependencies and from experience it surely will make it a lot harder for future system upgrades.
Thank you for your time.
