[Coin-discuss] Compilation error

[Cezik, Tolga]

No I'm not normally using GLPK (I use CLP) but I compiled everything linked with GLPK-4.9 libraries etc...as well. I want the tests to pass since I would like to try and compare GLPK some time later...I use Linux OS and gcc version 3.2.3 (Red Hat Linux 3.2.3-47). Thnx,
--tolga

Well, the unit tests *should* pass.  That's why they're unit tests 8^).

You're using GLPK as a solver?  What version?  What OS/compiler and versions?
