question about the process of cmake -B build -DCMAKE_BUILD_TYPE=Release ande cmake --build build -- -j

How to resolve the issue of mixed linking between libc++ and libstdc++? The Open3D library is compiled with libc++ (LLVM's C++ standard library), while other parts of the project use libstdc++ (GCC's C++ standard library), resulting in symbol conflicts. What should be done to fix this problem?

It would be better to help us identify the issue if you can provide the error details. Based on your description, it appears that the two parts were compiled using different compilers. You can try forcing the project to use the same compiler as Open3D. Make sure to add an extra flag during the build process and remember to delete the previous build folder beforehand.

sudo apt install clang
cmake -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=clang++
cmake --build build -- -j
