2017-10-29	Use ${WRKDIR}/tmp for temporary files instead of $(mktemp -d)	khorben	2	-6/+6
	This is more portable. As suggested by joerg@.
2017-10-28	Fix local privilege escalation when building math/lp_solve	khorben	2	-16/+98
	This still requires $TMPDIR (or /tmp) to be mounted with "exec", but now respects $TMPDIR.
2017-07-13	Honor LDFLAGS. Fixes RELRO build.	wiz	3	-6/+6

2016-09-08	Update to lp_solve_5.5.2.3 and indicate a 64-bit platform for aarch64	richard	2	-3/+29
	Fix isnan() checks to declare main() returning 'int' and use floating argument to isnan() avoiding recent (gcc 5) compiler noise. Since last update: ../../.. version 5.5.2.1 - fixed a small error in new and improved MIP_stepOF function to find integer solutions. ../../.. version 5.5.2.2 - For integer models with semi-cont variables it happened sometimes that a message "fillbranches_BB: Inconsistent equal-valued bounds for ..." occured and that the semi-cont condition was not respected. - New functions added: get_accuracy to get the numeric accuracy after solve. - New functions added: set_break_numeric_accuracy, get_break_numeric_accuracy to let lp_solve return ACCURACYERROR instead of FEASIBLE when numerical accuracy if worse then the provided values. In the past, lp_solve only returned a non-optimal status in case of very severe numerical instability. Now it will return already ACCURACYERROR when it finds a relative inaccuracy of 5e-7 - When reading a model from the lp-format and important issues are detected such as already bounds on variables being overruled later with for example a bin keyword, this is now reported in the default verbose level such that this is seen easier. 08/05/16 version 5.5.2.3 - For some models with integer variables, lp_solve did not find the most optimal solution.
2015-12-08	Link shared library against libdl, when necessary. It's an unnecessary	joerg	1	-0/+13
	imeplementation detail for consumers. Bump revision.
2015-12-07	Fix build on platforms that actually need -ldl. Improve the ftime	joerg	4	-8/+26
	removal.
2014-05-12	Fix build under OpenBSD/amd64 5.5	ryoon	1	-0/+16

2010-10-16	Initial import of lp_solve-5.5.2.0:	wiz	1	-0/+29
	lp_solve is a Mixed Integer Linear Programming (MILP) solver. It is a free linear (integer) programming solver based on the revised simplex method and the Branch-and-bound method for the integers. lp_solve solves pure linear, (mixed) integer/binary, semi-continuous and special ordered sets (SOS) models.
