with the +contrib variant

[Schamschula (Marius Schamschula)]

Hmm. We are downloading the same source code as a .tar.gz and .zip file?

[Schamschula (Marius Schamschula)]

I updated the checksums for the .zip file. The file is significantly smaller in size.

I get the following error:

CMake Error at cmake/OpenCVModule.cmake:288 (message):
  No modules has been found:
  /opt/local/var/macports/build/_Users_marius_Development_MacPorts_ports_graphics_opencv/opencv/work/opencv_contrib-3.4.8/modules
Call Stack (most recent call first):
  cmake/OpenCVModule.cmake:370 (_glob_locations)

-- OpenCV Python: during development append to PYTHONPATH: /opt/local/var/macports/build/_Users_marius_Development_MacPorts_ports_graphics_opencv/opencv/work/build/python_loader

with and with the .zip file.

Have the modules been removed from the release?

Replying to Schamschula:

Hmm. We are downloading the same source code as a .tar.gz and .zip file?

No, it's the same version number but a different repo. Yes, it would be better to use filenames that aren't just a version number.

[ryandesign (Ryan Carsten Schmidt)]

GitHub supports this. (You can request the file with any filename as long as the tag name before it is correct.) The github portgroup does so automatically, but since this port uses more than one file it can't benefit from the portgroup.

[Schamschula (Marius Schamschula)]

I get the following error extracting the .zip file:

Executing:  cd "/opt/local/var/macports/build/_Users_marius_Development_MacPorts_ports_graphics_opencv/opencv/work" && /usr/bin/gzip -dc '/opt/local/var/macports/distfiles/opencv/3.4.8.zip' | /usr/bin/tar -xf - 
gzip: /opt/local/var/macports/distfiles/opencv/3.4.8.zip: not in gzip format

[jmroot (Joshua Root)]

Yeah, it isn't setting use_zip (because the main distfile is still gzip). Using distinct filenames would help with that since both could then use .tar.gz. Otherwise the main distfile should be the only thing in extract.only and the zip file would have to be extracted in a post-extract block.

In c1037690a786fc294f1858ef544d02336eb520ab/macports-ports (master):

opencv +contrib: checksum mismatch

Closes: #59715
also work around issues with the .zip archive
