[package] OPENCV/4.5.x: OPENCV is being built with Werror GCC12 #16354

Open MattBelanger321 opened 1 year ago

MattBelanger321 commented 1 year ago

Description

There is a function in the library that has an Assert(false) instead of a return value but conan forces OpenCV to be built with -Werror=return-type so this is treated as an error.

src/modules/gapi/src/compiler/gislandmodel.cpp:124:1: error: control reaches end of non-void function [-Werror=return-type] 124 | }

I saw that warning was corrected in the opencv issues so maybe this can be a simple as adding the fix to conan

Have you solved this error?

ybe this can be a simple as adding the fix to conan

matheusgomes28 commented 1 year ago

I am slso getting "error: control reaches end of non-void function [-Werror=return-type]" when building the gapi file: ~/.conan/data/opencv/4.5.5///build/2d1073e04ab069672479e5d847b9070b3b0cca28/src/modules/gapi/src/compiler/gislandmodel.cpp:

I'm trying to manually set -Wno-error -Wno-return-type manually via CXX, CMAKE_CXX_FLAGS environment variables but the build seems to ignore those. Really painful as I cannot build OpenCV through conan on gcc121

Has anyone figured how to build this yet?

Valetron commented 1 year ago

I think, this is not conan error. I tried to build OpenCV 4.5.2, 4.6.0 from official repo manually and met the same error. I used next flags:

cmake -D CMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=./install -DWITH_CUDA=OFF -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules  -DWITH_QUIRC=OFF -DBUILD_JAVA=OFF ..

The version 4.7.0 was the only successful to build.

MattBelanger321 commented 1 year ago

Its not conan but OpenCV corrected this error already. Do they need need to upload to cinan again or something?

MattBelanger321 commented 1 year ago

did you build version 4.7.0 using conan? I do not see 4.7.0 here: https://conan.io/center/opencv , I am curious to how you accomplished this. I am using conan version 1 as an FYI
