[aravis] add new port (+add to OpenCV 4 as optional feature) #42351

rursprung · 2024-11-25T17:58:07Z

please note:

i'm not part of the aravis maintainers (i'm just a user)
i've tested this under Ubuntu 24.04 in WSL2 using a USB3 VISION camera through OpenCV (with the new aravis feature introduced in this PR) and it worked fine
aravis currently builds a couple of binaries (arv-camera-test-0.8, arv-fake-gv-camera-0.8, arv-test-0.8 and arv-tool-0.8) which cannot be disabled at the moment (except with a patch to their build system), i've reported this to upstream: add meson option to build only the library AravisProject/aravis#962. i think they currently don't hurt and it's better if this gets fixed in upstream rather than having a patch here.
back in 2019 @cenit already once attempted to package aravis here but that PR was abandoned later: [aravis] new port #8595

resolves #37072
resolves #3411

checklist:

ports/opencv/vcpkg.json

dg0yt · 2024-11-25T18:08:12Z

ports/opencv4/vcpkg.json

+    "aravis": {
+      "description": "aravis",
+      "dependencies": [
+        "aravis"


Enable opt-out from usb.

Suggested change

"aravis"

{

"name": "aravis",

"default-features": false

}

then it might be better to leave usb away as a default feature from aravis? i now went with that option to stay aligned with aravis (though i think they make it dependent on the availability of the library by default since they set it to auto)

vcpkg will install aravis' default feature by default. This change enables the user to explicitly request installation of aravis without default features.

ports/aravis/vcpkg-cmake-wrapper.cmake

+include(FindPkgConfig)
+pkg_search_module(Aravis REQUIRED aravis-0.8)
+if (Aravis_FOUND)
+    set(Aravis_LIBS "aravis-0.8")
+endif()


This wrapper is pointless and not working correctly.
The code should be added to the consuming projects instead.

without this wrapper i can't do find_package(Aravis REQUIRED) - i didn't find any documentation on how to resolve this (even vcpkg-cmake-wrapper.cmake is undocumented beyond the fact that it may exist). how else would you solve this?

dg0yt · 2024-11-25T18:11:18Z

ports/aravis/usage

+The aravis package provides CMake targets:
+
+    find_package(aravis REQUIRED)
+    target_link_libraries(main PRIVATE ${Aravis_LIBRARIES})


Don't add a usage file here. The tool generates the desired information heristically for pkg-config.

ok, i've removed it.
but then it just says:

aravis provides pkg-config modules: # Camera control and image acquisition library aravis-0.8

isn't this less helpful than having a clear example on what to do (as is e.g. the case with the usage i had provided)?

rursprung · 2024-11-25T19:29:00Z

@dg0yt: thanks a lot for your super fast review!

i now have one last CI failure in the android CI builds which i don't know how to solve:

../src/0.8.33-e9321ff061.clean/src/arvnetwork.c:352:6: error: call to undeclared function 'getifaddrs'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  352 |         if (getifaddrs (&ifap) <0)
      |             ^
../src/0.8.33-e9321ff061.clean/src/arvnetwork.c:390:2: error: call to undeclared function 'freeifaddrs'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  390 |         freeifaddrs (ifap);
      |         ^
2 errors generated.

based on labstreaminglayer/liblsl-Android#4 (unrelated library, just found the error description there) this is caused when using a too-old Android NDK as these methods were implemented more recently (Android NDK 24, see also the source code). is there a way to force the CI to build with a newer android SDK version for this port (though the log file does talk about android-ndk-r27c in the path)?

also, i just got this result on windows in the CI:

-- Performing post-build validation
D:\a\_work\1\s\ports\aravis\portfile.cmake: warning: The following executables were found in ${CURRENT_PACKAGES_DIR}/bin or ${CURRENT_PACKAGES_DIR}/debug/bin. Executables are not valid distribution targets. If these executables are build tools, consider using `vcpkg_copy_tools`. To suppress this message, add set(VCPKG_POLICY_ALLOW_EXES_IN_BIN enabled)

note: bin/arv-fake-gv-camera-0.8.exe
note: bin/arv-test-0.8.exe

i guess i do need to add a patch for the build after all to skip generating these bins (at least until it's done in upstream)?

dg0yt · 2024-11-26T03:34:27Z

The Android problem is not the NDK (vcpkg CI has r27c) but the API level (vcpkg uses 21 as default).
For now, you must add the expected fail to scripts/ci.baseline.txt, with a comment similar to the existing ones.
(Changing vcpkg android defaults is #42080.)

dg0yt · 2024-11-26T06:28:12Z

For the executables in bin, the port is expected to call vcpkg_copy_tools. It will move them to tools/<PORT>, and deploy DLLs for windows.

cenit · 2024-11-26T09:09:28Z

would you mind adding aravis feature to the vcpkg-ci-opencv port, so that it is tested in CI?

rursprung · 2024-11-26T21:46:32Z

it seems that OpenCV doesn't find Aravis on Windows with their detect_aravis.cmake. i'm out of my CMake depth here - any chance that you see the problem here @dg0yt or @cenit?

would you mind adding aravis feature to the vcpkg-ci-opencv port, so that it is tested in CI?

i've added it (as a dedicated entry due to having to add "platform": "!android"); it'll be part of the next push (will wait until i know more about windows; don't want to stress CI too much as it seems to run for hours on end 😮)

dg0yt · 2024-11-27T06:08:46Z

Unfortunately, the CI failure logs weren't uploaded.

rursprung · 2024-11-27T06:46:27Z

Unfortunately, the CI failure logs weren't uploaded.

here's the relevant excerpt from vcpkg/buildtrees/opencv4/config-x64-windows-out.log from my local build on windows x64:

then it complains about missing glibconfig.h
but it is nowhere to be found on the windows glib-2.0
i will explore it better soon

to better speed up the work, please let me be a contributor to your fork so that i can quickly add everything that i find

rursprung · 2024-11-27T17:27:17Z

thank you for looking into this! i've added you as a collaborator.

is flagging the dependencies as REQUIRED not interfering with the case when WITH_ARAVIS is not enabled? (i'm not sure if it also calls detect_aravis.cmake in that case or not)

cenit · 2024-11-27T20:07:04Z

detect_aravis.cmake should be called only if aravis is required. And in that case those findings are required, not optional, so that's the rationale adopted also in other opencv patches

cenit · 2024-11-27T22:57:50Z

added the patch so that you know the current state of art. We will need to work on the aravis_libraries list and append missing glib ones to fully fix the link errors

cenit · 2024-11-28T09:58:41Z

drastically simplified (does not even need a new patch anymore and it builds here)

rursprung · 2024-12-11T06:32:10Z

@dg0yt & @cenit: i'd very much appreciate any insight you might have into why the build is broken (see my previous comment) - i lack the experience in this area (and at the moment completely lack time). it'd be great if we could get this working & merged!

dg0yt · 2024-12-11T07:03:36Z

Ah, I forgot to add a note.

The linker line has everything which is need. However, the linux toolchain has what CMake calls a "traditional linker": The order of static libraries matters. But here CMake doesn't provide link libs correctly. We have seen this before, and we don't know the exact triggers :-(
(It is somewhat related to link libs appearing as targets - with explicit depedencies - versus being items in list variables (<Foo>_LIBRARIES) or in lists in target properties (INTERFACE_LINK_LIBRARIES) - implicitly expressing dependencies, but not binding for CMake.

Unfortunately, I can't provide more help ATM.

cenit · 2024-12-14T08:55:04Z

i have the same error in my opencv PR
Once it will be fixed there and it is accepted, it should disappear also from your PR

thjordanatlas · 2025-01-28T14:15:02Z

What is blocking this from being merged to vcpkg? I would be so happy to have this available and thank you all for your great work in this!

thanks a lot @cenit! i saw the other PR getting merged (great works, thanks for keeping on it for that long!) and was about to rebase this PR here, but you beat me to it

cenit · 2025-02-04T10:28:57Z

you can undraft this one, so that if the flag is green it can be accepted asap

rursprung · 2025-02-04T19:56:15Z

i've marked it ready for review + rebased it due to "This branch must not contain merge commits.". the verify ran through successfully before, so it should be fine now 🤞

note: i do not have access to an aravis-compatible camera anymore (neither USB vision nor GigE vision), so i can't re-test the actual functionality after the rebase! hopefully someone with such a camera could re-test this? (@thjordanatlas: based on your comment you seem to have such a camera since you would like to use this - could you maybe give this PR a try? thanks!)

AenBleidd · 2025-02-05T20:37:45Z

@rursprung, on behalf of @thjordanatlas:
we can test this but this might take a while (not top priority task for us at the moment), so I'd suggest to move forward and merge this PR.
After we do the test, we will provide feedback and open an issue if there will be something found on our side.

thjordanatlas · 2025-02-07T07:03:08Z

Sorry for the late reply, I am busy with other projects, but will try as soon as I can and give feedback. Thank you for work work!
