Linking errors when building in Ubuntu container

[fantomid]

I created image to build MoonRay in Ubuntu's containers (Ubuntu versions 22.04 and 20.04). The first tool that doesn't link is denoise: [35%] Linking CXX executable denoise /usr/bin/ld: ../../lib/rendering/rt/librendering_rt.so: undefined reference to vtable for moonray::pbr::ProjectiveCamera' /usr/bin/ld: ../../lib/rendering/rt/librendering_rt.so: undefined reference tomoonray::pbr::PerspectiveCamera::PerspectiveCamera(scene_rdl2::rdl2::Camera const)' /usr/bin/ld: ../../lib/rendering/rt/librendering_rt.so: undefined reference to moonray::pbr::ImageDistribution::~ImageDistribution()' /usr/bin/ld: ../../lib/rendering/rt/librendering_rt.so: undefined reference tomoonray::pbr::Camera::update(scene_rdl2::math::Mat4<scene_rdl2::math::Vec4 > const&)' /usr/bin/ld: ../../lib/rendering/rt/librendering_rt.so: undefined reference to `moonray::pbr::PerspectiveCamera::computeFrustumImpl(moonray::mcrt_common::Frustum, float, bool) const' collect2: error: ld returned 1 exit status make[2]: *** [moonray/moonray/cmd/denoise_cmd/CMakeFiles/denoise.dir/build.make:149: moonray/moonray/cmd/denoise_cmd/denoise] Error 1

The other one are in the test directory. I got the same linking's errors for moonray_rendering_rt_tests. I got this error for moonray_rendering_pbr_tests. /usr/bin/ld: ../../../../lib/rendering/pbr/librendering_pbr.so: undefined reference to `isRenderCanceled'

If I made these libraries static (rndr, pbr, rt), the linking's errors disappeared. Could someone explain ? With CLang, I got errors too.

I haven't seen this issue before...

PerspectiveCamera should be in librendering_pbr.so. If you run the build with the --verbose option, it should show the linker command line being run for denoise : -lrendering_pbr should be listed.

You can check if moonray::pbr::PerspectiveCamera::PerspectiveCamera(scene_rdl2::rdl2::Camera const*) actually is defined in librendering_pbr.so using nm:

nm librendering_pbr.so | fgrep PerspectiveCamera ... T _ZN7moonray3pbr17PerspectiveCameraC1EPKN10scene_rdl24rdl26CameraE ... c++filt _ZN7moonray3pbr17PerspectiveCameraC1EPKN10scene_rdl24rdl26CameraE moonray::pbr::PerspectiveCamera::PerspectiveCamera(scene_rdl2::rdl2::Camera const*)

Sorry for the delay, holidays :) I already did the checking with nm and c++filt before reporting the linking issues. Could gnu c++17 option be responsible of these errors ?

I will give you the linker command with verbose option at the beginning of august.

@rgwilson68 the command line of the linker: [ 35%] Linking CXX executable denoise cd /build_dir/build-release/openmoonray/moonray/moonray/cmd/denoise_cmd && /opt/cmake-3.23.1-linux-x86_64/bin/cmake -E
