[SCIP] Shared library build of SCIP on Mac OS X with gcc

[Matthias Koeppe]

I'm trying to make a shared library build of SCIP on Mac OS X with gcc.
Is this supposed to be a supported configuration?
I suspect it is not, because of the error that I get (see below) and
the fact that there is no sign of the "dyld" extension used by Mac OS
X in any of the Makefiles.
Any thoughts?


Concretely, I'm using the scipoptsuite 3.2.1 source package and trying
to build within SageMath, which brings its own gcc 4.9.2.

I'm running:

make VERBOSE=true SHARED=true USRLDFLAGS="$LDFLAGS"
USRCXXFLAGS="$CXXFLAGS" USRCPPFLAGS="$CPPFLAGS" USRARFLAGS="$LDFLAGS"

which ends with the following error:

It seems to help to add "-lgmp -lz" on this command line.
