Triangle won't compile.. "error: triangle/core.c: No such file or directory" #12

Hi there,

I just downloaded the git repository and tried to install it. However I am experiencing the following problem. Any suggestions?

For some reason on your system triangle/core.pyx does not get converted to triangle/core.c. Do you have Cython installed?

tfabbri commented 8 years ago

I think the fix that I posted should work also in this case.

I've installed (in order of errors that came in during installation): setuptools python-dev Cython 0.2 python-pyrex

Linux Mint 17.2

UPD. I've find an one half of an answer. I've deleted python-pyrex (think, Cython and Pyrex came into conflict, maybe) and now I have:

running install running bdist_egg running egg_info writing requirements to triangle.egg-info/requires.txt writing triangle.egg-info/PKG-INFO writing top-level names to triangle.egg-info/top_level.txt writing dependency_links to triangle.egg-info/dependency_links.txt reading manifest file 'triangle.egg-info/SOURCES.txt' reading manifest template 'MANIFEST.in' writing manifest file 'triangle.egg-info/SOURCES.txt' installing library code to build/bdist.linux-x86_64/egg running install_lib running build_py running build_ext building 'triangle.core' extension error: unknown file type '.pyx' (from 'triangle/core.pyx')

Now I'm trying a solution from @tfabbri.

UPD2 It doesn't work. I've installed cython - 0.24 then, in setup.py I've changed setup_requires=[ 'setuptools>=18.0', 'Cython>=**0.24**' ], install_requires=[ 'numpy>=1.7.0', 'Cython>=**0.24**' ], What can i do now? error: unknown file type '.pyx' (from 'triangle/core.pyx')

UPD3 I've deleted string 'triangle/core.pyx' from setup.py

ext_modules=[ Extension('triangle.core', [ 'c/triangle.c', 'triangle/core.pyx' ], include_dirs=['c'], define_macros=define_macros) ]

then - no errors, I've deleted package by pip and then I've installed it again with 'triangle/core.pyx'.

And it works!

It doesn't works in python. When I write import triangle in python interpreter I get: >>> import triangle Traceback (most recent call last): File "<stdin>", line 1, in <module> File "triangle/__init__.py", line 4, in <module> import triangle.core as core ImportError: No module named core

JohnCC330 commented 8 years ago

Basically, I have the same problem. The original .tar.gz contains a triangle/core.pyx which causes the message: error: unknown file type '.pyx' (from 'triangle/core.pyx') I thought Pyrex wasn't necessary for the project (I read it was replaced by Cython). In also tried installing Pyrex (0.9.9), but then I get the following error:

...

Indeed, there is no triangle/core.c

Finally, I tried to simply run pip install triangle, as advised in http://blancosilva.github.io/post/2014/10/28/Computational-Geometry-in-Python.html, but gives the same error as the previous try.

I was also having the issue described by the first two complainants (after getting Cython version 0.24) on Ubuntu 14.04. I managed to resolve it by uninstalling my system's setuptools (version 3.3) and getting the latest version of setuptools with pip (version 23.0) (what a difference, jeez!!) Since Ubuntu's pip depends on python-setuptools, I also had to reinstall pip not through apt but through the maintainers' own installation script:

sudo apt-get remove python-setuptools
wget https://bootstrap.pypa.io/get-pip.py
sudo -H pip install -U pip setuptools

Now, the following error when installing triangle was encountered:

Traceback (most recent call last):
  File "setup.py", line 1, in <module>
    from setuptools import setup, Extension
  File "/usr/local/lib/python2.7/dist-packages/setuptools/__init__.py", line 11, in <module>
    from setuptools.extern.six.moves import filterfalse, map
  File "/usr/local/lib/python2.7/dist-packages/setuptools/extern/__init__.py", line 1, in <module>
    from pkg_resources.extern import VendorImporter
ImportError: No module named extern

so after some googling, I also did: 

sudo apt-get purge python-pkg-resources
sudo apt-get -f install

(the second step didn't seem necessary in my case, but it can't hurt)

Now, I can install triangle both by cloning the git repo and running python setup.py install and by using sudo -H pip install triangle.

LonelyDeer commented 8 years ago

@sinback, thank you very much! It really works. But can you explain it to me? What did we do?

  1. sudo apt-get remove python-setuptools ok, we just removed setuptools (and pip too, look item 3)
  2. wget https://bootstrap.pypa.io/get-pip.py we said "Hey, Linux - loook there" - we have inserted new repository
  3. sudo -H pip install -U pip setuptools I don't what is -H and "-U". Than pip install is a command to use pip to install a package pip setuptools. Is here a mistake? Because this string call an error like "unknown command pip". I'have installed pip by python get-pip.py with file get-pip.py from this site. Then i've did sudo apt-get purge python-pkg-resources sudo apt-get -f install sudo -H pip install triangle

And all works. Thank you @sinback. Thank you @drufat.
