C++ compiler giving segmentation fault while trying to compile euclidean_resection.cc (OpenCV with CUDA Enabled)

[nirav.jani]

I have been trying to compile opencv 4.4.0.

Attached are the build and configuration log. My board is jetson nano (https://developer.nvidia.com/embedded/jetson-nano-developer-kit)
having image from - https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit#write

This compiler segmentation fault happens each time at same place . (euclidean_resection.cc - compilation)
Tried options:

1. Increasing swap memory (currently total swap memory is 6G)
2. Compiling with make (without any processor number specified)
3. Compiling with make -j1
4. Tried to compile 4.5.1, 4.5.2, 4.1.1, 4.4.0 - all are failing at same file compilation
5. Cross compilation with cuda support enabled on VM - Ubuntu 18.04 - facing configuration issues

build.log (142.1 KB)
configure.log (27.9 KB)

Need help on…

1. Segmentation fault while trying to compile the euclidean_resection.cc file in cc1plus program (C++ compiler) - request to see attached screen shot
2. Document/thread listing out steps for cross compilation of opencv on ubuntu VM (with CUDA/GPU support enabled)

Your help is highly appreciated as have been stuck here since quite some time and am relatively new to the world of CUDA/GPU support in OpenCV.

I successfully built opencv 4.5.4 with clang-10 (-D CMAKE_CXX_COMPILER=clang+±10)

It seems to be a problem of libmv_light or gcc.

I build an incomplete opencv by commenting out:

“euclidean_resection.cc fundamental.cc fundamental_kernel.cc
homography.cc robust_resection.cc robust_fundamental.cc
robust_estimation.cc projection.cc panography.cc
panography_kernel.cc” in opencv_contrib/modules/sfm/src/libmv_light/libmv/multiview

but it does not work when I import it from python3:

Thanks 1332019995 for reply!

I could resolve it with the default clang compiler. (/usr/bin/clang++), compiled latest 4.5.4 OpenCV with clang++.

My configure and build logs after successful compilation are attached herewith for some one to refer.

So there seems to be some problem with the g++ compiler coming up with jetpack sdk image for jetson nano - but not the opencv.

configure.log (29.5 KB)

Hi all,
Compile OpenCV4.5, please follow this topic"

I compiled opencv 4.5 but did not update Python-Opencv - Jetson & Embedded Systems / Jetson Nano - NVIDIA Developer Forums

[nirav.jani]

If any one has done it without clang++ compiler (on jetpack 4.6 and opencv 4.5.1 onward with cuda/dnn support enabled) - please share your steps/experience.
