Thank you for your bug report. The bug has been fixed in recent versions of glpk. > What is the best way to upgrade from 4.40 to 4.47. Why doesn't > yum automatically install the latest version? You may build glpk from sources by yourself. The GLPK distribution tarball can be found on http://ftp.gnu.org/gnu/glpk/ [via http] and ftp://ftp.gnu.org/gnu/glpk/ [via FTP]. For installation instructions see file INSTALL. Note that most recent version is 4.50. > Code which results in these 2 problems: It was an unsuccessful attempt to measure the time using only standard ANSI C functions. Currently glpk uses a configurable code which includes a Posix-specific version as well. _______________________________________________ Bug-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-glpk
