Compiling SCIP: 'spxsolver.h' file not found

I am trying to compile SCIP using the following command: 

make ZLIB=false READLINE=false GMP=false

Anyone has idea how to handle this issue? 

-> compiling obj/O.darwin.x86_64.gnu.opt/lib/objscip/objsepa.o
-> compiling obj/O.darwin.x86_64.gnu.opt/lib/objscip/objvardata.o
-> generating library lib/libobjscip-3.1.1.darwin.x86_64.gnu.opt.a
-> compiling obj/O.darwin.x86_64.gnu.opt/lib/lpi/lpi_spx.o
src/lpi/lpi_spx.cpp:76:10: fatal error: 'spxsolver.h' file not found
#include "spxsolver.h"
         ^
1 error generated.
make[1]: *** [obj/O.darwin.x86_64.gnu.opt/lib/lpi/lpi_spx.o] Error 1
make: *** [libs] Error 2

Note: I am using Mac OS X Yosemite 10.10.3

The problem was that I was installing the scip-3.1.1.tgz rather than scipoptsuite-3.1.1.tgz. Running make on scipoptsuite-3.1.1.tgz runs perfectly fine.

SCIP uses external LP-solvers such as SoPlex (by default) as underlying LP-solver. The LP-solver needs to be linked in at compilation time. Here is how you do that:

  1. Download and unpack SoPlex and compile it in a separate directory, e.g., ~/soplex
  2. Link SoPlex into SCIP. The easiest way is to call make links from your SCIP directory

Please refer to the Installation guide of SCIP for more details, especially the step-by-step example No. 1.
