fvdb setup fails using /lib/. instead of /lib64/. and nksr-cuda setup 'include fvdb error'

[ostjul]

Thanks for the code release and great paper! The setup of fvdb seems to work fine on my system with one exception, that I could fix. Following your installation instructions on a linux server I experienced the following build error:

cannot find external/c-blosc/install/lib/libblosc.a: No such file or directory

A solution that worked for me was changing the path in the setup file. In openvdb/fvdb/setup.py line 264: (...) extra_objects=['external/c-blosc/install/lib/libblosc.a'] + cudnn_static_libs, needs to be changed to extra_objects=['external/c-blosc/install/lib64/libblosc.a'] + cudnn_static_libs, if the systems default is building the 64bit version in lib64. Otherwise, it fails to find libblosc.a. Seems to be related to an easybuild/GCC compiler issue.

While I can import fvdb python packages now in the nksr-cuda setup #include <fvdb/GridBatch.h> doesn't work and I could not figure out the right referencing myself yet.

@ostjul I had the same problem but was able to fix it by copying the include dir from my build folder after the fvdb install. See below for what I ran.

cd openvdb/fvdb
cp -R build/lib.linux-x86_64-cpython-39/fvdb/include fvdb/include

Thanks a lot @rfeinman, it worked after copying all files from fvdb/include/nanovdb/nanovdb to fvdb/include/nanovdb

Hi, this coud also be fix by:

# Install sparse 3D deep learning framework 
git clone https://github.com/AcademySoftwareFoundation/openvdb.git
cd openvdb
git fetch origin pull/1808/head:feature/fvdb
git checkout feature/fvdb
rm fvdb/setup.py && cp ../assets/setup.py fvdb/
cd fvdb && python setup.py develop
cd ../..

# Mesh extraction
cd ext/nksr-cuda
python setup.py develop
cd ../..

@xrenaa Thanks for your guidelines! I followed the provided instructions and also copied the files as @rfeinman has mentioned before, but I met a problem: x86_64-conda-linux-gnu-c++: error: unrecognized command-line option '-march' It seems that the c++ version is not suitable, how can I fix this bug?

Thanks for your reply!

Hello, after following the above steps and running the infer code, I encountered the following error:

openvdb/fvdb/fvdb/libfvdb.so: undefined symbol: _ZN2at4_ops13scalar_tensor4callERKN3c106ScalarESt8optionalINS2_10ScalarTypeEES6_INS2_6LayoutEES6_INS2_6DeviceEES6_IbE

Can you please help me solve this issue?

cd openvdb/fvdb
cp -R build/lib.linux-x86_64-cpython-39/fvdb/include fvdb/include

Could you please tell me how to install fvdb? I using pip install fvdb failed.Thanks

Solved according to this:

直接在 xcube 的根目录下执行，不过要把一行进行修改： rm fvdb/setup.py && cp ../assets/setup.py openvdb/fvdb/ to rm fvdb/setup.py && cp ../assets/setup.py fvdb/
