[SCIP] Error compiling SCIP using Cygwin

[Ahmed Hammad]

Hi Matthias,


I tried extending "CPPFLAGS" parameter but I still get the same error. This is how I extended CPPFLAGS (I attached "make.cygwin.x86_64.gnu" above too) :


CPPFLAGS += -m64LDFLAGS  += -m64ifneq ($(OPT),opt-gccold)ifneq ($(OPT),dbgOFLAGS          +=      -mtune=native  # -malign-double -mcpu=pentium4 endif
endif

ifeq ($(SHARED),true)
LIBBUILDFLAGS += -D_WIN64 +=      -m64
endif


When I tried using LEGACY=true I got the following error:

** Building ZIMPL library "/scipoptsuite-3.2.1/zimpl-3.3.3/lib/libzimpl.cygwin.x86_64.gnu.opt.a".

make: *** [scipbinary] Error 2

Thanks for your help

Ahmed

Dear Ahmed,

for some reason the flag "_WIN32" or "_WIN64" is not set when using cygwin. You can do that manually be adjusting the corresponding sub-makefiles "make.cygwin.x86.gnu" or "make.cygwin.x86_64.gnu" in "soplex-2.2.1/make/":
Simply add " -D_WIN32" or " -D_WIN64", respectively,  in the first line, extending the "CPPFLAGS" parameter.

Hope that helps!
You might also try the make option "LEGACY=true", disabling the rational solving capabilities of SoPlex.

cheers
Matthias

Hello all,


I have been trying to compile SCIP on windows using Cygwin. So I downloaded scipoptsuite-3.2.1. Once I untar it and try to built it using make I get the following error when it tries to build the Soplex library:

How to I deal with this. Please help
