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

Tue Jul 26 14:50:58 CEST 2016

Hi Matthias,

please excuse us for not replying earlier.

I just tried to compile the SCIP Opt Suite 3.2.1 on a Mac and worked 
without issues (using the clang compiler); also PySCIPOpt works fine 
with this library. It does indeed generate a .so library instead of an 
.dylib but a at least according to this SO thread this does not seem to 
be a problem:

https://stackoverflow.com/questions/2339679/what-are-the-differences-between-so-and-dylib-on-osx

Concerning your difficulties with the compilation for Sage, I don't 
understand why you're compiling every component on its own instead of 
using the SCIP Opt Suite Makefile. You should only need the 
libscipopt.so and the include path of SCIP.

all the best
Matthias
