Sage not finding Gambit's command line tools

[James Campbell]

Hi,

I'm trying to get Gambit working as an external package.

I followed through the steps about packaging third party code and I'm now at the stage where running ``import gambit`` within sage does not raise any errors.

I have access to to the majority of the functionality within gambit, however, Gambit has some function which rely on a corresponding command line tool.

I can see that these have appeared in 'SAGE_ROOT/local/bin` but when I try to use them within sage I get the error `'module' object has no attribute 'nash'` for example.

Is there something I've forgotten to do?

all help is greatly appreciated, thanks

did you install them using 'sage -sh' ?

Are you able to run these tools using Sage's python (i.e. from 'sage
--python') ?

If the latter works this means there are some incompatibilities
with most probably Sage's preparser and the code in question.
(fixable, but not instantly...)

Well, hard to tell without looking at your package.

Is it available somewhere? Trac ticket?

P.S.: This seems to be more suited to discuss on sage-devel.

Yes I did install using sage -sh.

No, I haven't tried using them within Sage's python. If they don't work there

what would be the solution?

Thanks for the help

You can find a github repository here: https://github.com/theref/sage-game-theory/tree/16333 (that's the branch to the corresponding trac ticket which you can find here: http://trac.sagemath.org/ticket/16333)

I completely agree, apologies for the late reply, James (student who is working on this) had missed your replies which are very much appreciated.

then it means that Gambit has hard time whenever your Python etc is
not at a "standard" location.

E.g. it could happen that a setup.py hardcodes a path to something
like /usr/local/...
This would need to be fixed.
A similar situation happens with cvxopt, where Sage has to patch
setup.py
Have a look at
https://github.com/sagemath/sage/tree/master/build/pkgs/cvxopt
in particular
https://github.com/sagemath/sage/blob/master/build/pkgs/cvxopt/patches/setup.py.patch

HTH,
Dima

Ok, thanks for all your help! I'll see what I can get sorted.
