[SCIP] Error compiling SCIP using Cygwin

Sat Apr 9 17:14:12 CEST 2016

Life would be lot easier for everyone if the Windows users that intensely use SCIP and
other such codes would learn a minimum of Linux, make their computer dual-boot
and run SCIP just under Linux. They have little experience with Makefiles etc and
are helpless in fixing problems. Of course, the opposite mode of using Windows as
base is propagated very much by Microsoft.

However, I require ZIMPL for the python interface using make SHARED=true scipoptlib. I still get an error even when I copied the previous ZIMPL files that you attached. The error is as follows when I run "make" (without setting ZIMPL = false):
