Error compiling im2mesh #2

Closed SilvioGiancola closed 5 years ago

SilvioGiancola commented 5 years ago

Hi, I am getting the following error while compiling im2mesh on Ubuntu 16.04:

(mesh_funcspace) giancos@PC-KW-60110:~/git/occupancy_networks$ python setup.py build_ext --inplace
running build_ext

Any advice?

Seems like you are missing numpy dependencies (also see here). Have you installed and activated the anaconda environment as described in the readme?

SilvioGiancola commented 5 years ago

Thanks for your support, I solved my problem with sudo apt-get install python-numpy. Impressive demo!

Hey guys! Note for anyone else who comes across this problem and doesn't have sudo:

I ran python and got numpy's include directory as follows

>>>import numpy as np
>>>np.get_include()
/nethome/user/.../include

I then did export CFLAGS="-I/nethome/user/.../include $CFLAGS" And I was able to compile!

One thing that could also be done is on line 106-111 change to include numpy include directory:

setup(
    ext_modules=cythonize(ext_modules),
    include_dirs=[numpy_include_dir],
    cmdclass={
        'build_ext': BuildExtension
    }
)

After that it works flawlessly

A simple fix to generalize @rmichnovicz and @dsvilarkovic 's ideas:

setup(
    ext_modules=cythonize(ext_modules),
    include_dirs=[numpy.get_include()],
    cmdclass={
        'build_ext': BuildExtension
    }
)

where exactly to add?

In setup.py replace lines 106-111 to the thing I wrote
