Hi,
I never had this error as I am using debian which have gcc with
libgomp install by default. This error should happen only if the user
try to import omp while he doesn't support it. Do you import it in
all_pairs.py?
Medhi do you know where it comes from?
We should show full stacktrace (next PR?) for user debuging.
Best,
Pierrick

Hi Olivier,
You need to have gcc installed right now. (I think this is wrong and
this limitation should be lifted, Pythran should work without OpenMP
when unavailable).
If you use macport, gcc will be installed in /opt/local/lib
I launch it using:
LD_LIBRARY_PATH=/opt/local/lib/gcc48/ pythran all_pairs.py
Best,
Mehdi

I followed the indications for OSX on

But I get the following errors:

Couldn't import dot_parser, loading of dot files will not be possible.

E: I can't find a shared library for libgomp, you may need to
install it or adjust the LD_LIBRARY_PATH environment variable.
I could not find clear indication of what is wrong with dot_parser,
googling around.
which libgomp shows nothing and I could not find libgomp with brew /
brew cask.
My python in Anaconda 2.1
Pythran is not the easier to install and set up till now, but it
seems to have a very interesting potential, so I insist, and would
be grateful for some help.
Thx
Olivier
