 Hi,

 I tried to use a recent Soplex with !OsiSpx, but got into compilation
 problems.
 A quick-and-dirty patch that make it compiling and allow a simple
 createproblem-initialSolve-getsolution can be found at
 https://projects.coin-or.org/GAMSlinks/browser/trunk/osispx.patch

 However, trying to solve an LP of reasonable size with this modified
 !OsiSpx returned with unbounded while it should be feasible.

 Best,
 Stefan
