[gecode-users] Compiling Gecode in gcc 3.3 success

[Javier Mena]

The problem is that the file int/gcc/graphsup.icc has calls in the style:

vrn->matched<UBC>()

I have changed of all the calls to (that comforms c++ standard):

vrn->template matched<UBC>()

And it works. I have read the book of Stroustrup (The C++ Programming
Language), but I cannot understand if one should always have to use
the "template" keyword before that kind of calls. So, I can't
understand exactly why does the compiler doesn't recognize the call
sometimes.

After that there another problem. I cannot compile gecode because
there is a bug in gcc 3.3.6:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=7906

If I put away the file matrix.icc and all its dependencies (just
examples) gecode compiles.

What do you think?
