encoding problem in mac os x

Hi,

I managed to compile graph-tool 2.2.5 and to solve linking problems
with libcgal (thanks to tcb).
When I try to import the graph_tool module i got this error:

In [1]: import graph_tool.all as gt
------------------------------------------------------------
   File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/graph_tool/topology/__init__.py",
line 138
SyntaxError: Non-ASCII character '\xe2' in file
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/graph_tool/topology/__init__.py
on line 139, but no encoding declared; see
http://www.python.org/peps/pep-0263.html for details (__init__.py,
line 138)

do you have any idea?

Could you please share what kind of problem you had with linking to
cgal, and how you resolved it, so that I can incorporate the fix?

This is very strange... The error seems to say that there is some UTF-8
character in the file shown. However I see nothing of the sort, when I
inspect the file myself (and I don't get this error). Can you look at
the line 138 in the file to see if you find anything wrong? This line is
part of a docstring, so you can try removing it to see what happens.

What python version are you using?

I believe it's a problem with cgal's build in macports. basically when
i build graph_tool, the .so are linked to libCGAL with a relative
path:

tyler:~ hammer$ otool -L

Hm, not really... I have no idea why the full path is not used by the
linker.

I have now added encoding information in the python source files in the
git repository, so that even if the files include utf-8 characters, it
should not be a problem. Would you care to test if the problem is still
there?

once again, problems compiling with mac os x!

Hi folks,

i've succeeded to build latest graph-tool on my mac os x leopard, so i
tried building it on snow leopard machine to take advantage of its 8
cores.
macports are the same (boost 1.42, numpy 1.4.0, scipy 0.7.1) with gcc
(GCC) 4.4.3 but i get the attached error.

It doesn't sound familiar to me. do you have an idea?

Thanks,

Claudio

Baffling. Are you indeed 100% sure the gcc + boost combination is
_exactly_ the same as previously?

I don't have boost 1.42 at the moment, but it is a potential candidate
for regression... I'll try to test this when I have some time.

Cheers,
Tiago

Re: once again, problems compiling with mac os x!

no i am not sure. actually to test it i re-run the build on my system
(where i must have upgraded boost since last build) and got the same
error!
