Doesn't Oracle (Sun) hold the copyright and can issue a version with any license of their choice? became exclusive to LibreOffice, but I'll go ahead and spoil the fun: COIN-OR (www.coin-or.org) has a lot of OR code under the less-evil EPL or CPL licenses. Among it: Clp for linear programming, Cbc for integer conditions, and CoinMP, which wraps these in a single shared object with a C interface. I created issue 118160 and attached a simple proof-of-concept patch to use CoinMP instead of lp_solve. From some limited testing, this seems to work very well. Some changes will still be needed for building and packaging, and perhaps some tweaking of solver settings. But the patch shows that replacing lp_solve is clearly a (pardon the pun) solvable problem. Sounds promising, nevertheless. :) ---rony -- - To unsubscribe send email to dev-unsubscr...@openoffice.org For additional commands send email to sy...@openoffice.org with Subject: help
