[Scip] Problem compiling SCIP 2.0.0 with CLP: SCIPlpiHasDualRay

[Emilie Danna]

Hi,

I tried building SCIP 2.0.0 with CLP 1.12 and got the following error:

-> compiling obj/O.linux.x86_64.gnu.opt/lib/scip/lpi_clp.o
src/scip/lpi_clp.cpp: In function ‘unsigned int SCIPlpiHasDualRay(SCIP_LPI*)’:
src/scip/lpi_clp.cpp:2414: error: ‘class ClpSimplex’ has no member
named ‘rayExists’
src/scip/lpi_clp.cpp:2421: error: ‘class ClpSimplex’ has no member
named ‘deleteRay’
make: *** [obj/O.linux.x86_64.gnu.opt/lib/scip/lpi_clp.o] Error 1

If I replace the implementation of SCIPlpiHasDualRay with the code of
SCIP 1.2, then I can build SCIP without any problem.

Do ClpSimplex::rayExists and ClpSimplex::deleteRay exist for a
different version of CLP?
