Actually, I can't provide you an example. Math::GSL is a SWIG-generated Perl interface to the GSL library, but it looks like its maintained in a separate repository. > Is it sufficient to have glpk.h and libglpk to build a wrapper with > swig? I haven't tried, but i'm fairly sure it's possible. It would burden the user with having to deploy 2 libraries (libglpk and the wrapper library) instead of one, which might be undesirable for some people. But then, there are good arguments for keeping them separate as well. > Which lines in glpk.h cause problems? I did not find that > in your patch file. Lines 152-156: #define GLP_MSG_OFF 0 /* no output */ #define GLP_MSG_ERR 1 /* warning and error messages only */ #define GLP_MSG_ON 2 /* normal output */ #define GLP_MSG_ALL 3 /* full output */ #define GLP_MSG_DBG 4 /* debug output */ These lines are redundant (they are identical to lines 115-119) and i'm pretty sure they can be safely removed without breaking anything. When you try to run SWIG against glpk.h, SWIG complains about these lines. I can appreciate you hesitation about including the SWIG interface file in the GLPK source tree - it would be one more thing to maintain and it is peripheral to the fundamental purpose of the library. I know that i'm not the first person that has had a desire use GLPK from a language other than C - in fact, I stole the interface file from here: http://www.nabble.com/Re:-GLPK-and-Java-using-SWIG-tc10910553.html and made a few changes to it to suit my own tastes. I guess that i'm suggesting that by including the glpk.i interface file in the GLPK source tree, it might encourage others to use the SWIG-generated wrappers as a foundation for writing clean interfaces to GLPK in other languages. As it currently stands, someone that wants to do this has to jump through a few hoops (write the SWIG interface file glpk.i, make changes to glpk.h, etc). --Kelly _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
