#11958 closed defect (fixed)

cplex needs another symbolic link

Description

In order to get a current CPLEX to work with Sage, I had to add one more symbolic link to SAGE_ROOT/local/include/ than the directions at http://www.sagemath.org/doc/thematic_tutorials/linear_programming.html#installing-cplex indicated: 

ln -s /path/to/include/cpxconst.h .

Without this, sage -b complained about that file missing. With this new symbolic link, sage -b succeeds and I can solve an example problem with cplex.

So the docs probably should be updated.

O_o

I have been using CPLEX for (almost) years and I never met that. O_o

Which kind of version of it do you use ? O_o

Hello,

I'm able to install correctly the patch on sage-5.0.beta9, and it is very useful when you want to use cplex 12.4.

It took me some time to understand that I add to type sage -docbuild thematic_tutorials html for building the doc.

Thanks for the patch!

David.

I hope it's not too selfish to add myself as an author, as it did take a (short) while to track down the problem and solution...

Ahahah, be welcome in the "authors" field, there's room for everybody here so let us have a drink :-)

Anyway there clearly was more work involved in finding the bug than in writing this patch !
