• I have searched for similar issues.
• For Python issues, I have tested with the latest development wheel.
• I have checked the release documentation and the latest documentation (for main branch).

Steps to reproduce the issue

I first cloned Open3D by:

git clone https://github.com/isl-org/Open3D.git
cd Open3D

Then, I build Open3D (on Ubuntu 20.04, with CUDA 11.5) with:

mkdir build
cd build
cmake -DBUILD_SHARED_LIBS=OFF -DBUILD_CUDA_MODULE=OFF -DUSE_BLAS=ON -DBUILD_WEBRTC=OFF ..
make -j$(nproc)

Error message

gfortran: warning: could not understand version ‘14.00.00’
CMake Error at 3rdparty/find_dependencies.cmake:1700 (find_library):
  Could not find quadmath_lib using the following names: libquadmath.a
Call Stack (most recent call first):
  CMakeLists.txt:499 (include)

Open3D, Python and System information

- Operating system: Ubuntu 20.04 / macOS 10.15 / Windows 10 64-bit
- Python version: Python 3.8 / output from `import sys; print(sys.version)`
- Open3D version: output from python: `print(open3d.__version__)`
- System architecture: x86 / arm64 / apple-silicon / jetson / rpi
- Is this a remote workstation?: yes or no
- How did you install Open3D?: pip / conda / build from source
- Compiler version (if built from source): gcc 7.5 / clang 7.0

Additional information

I'm on M2 MacBook Air 2023. Although I tried to conda install gfortran, it still gives the same warning.

In addition, I tried to pip install the open3d, still same error and not imported.

Could anyone please help me with this?

Try, clone and open using github desktop version.

Please try prebuilt binaries for Open3D (viewer app, C++ devel libraries) for macOS arm64. If you want to build on your own, see docs/arm.rst
