[Scip] linking problems with icc

[Tobias Achterberg]

Hi Sandor,

did you already try the "make.linux.x86.intel.dbg.static" that is included in the make/ subdirectory 
of SCIP? (I don't really know, why there is no .opt-version). This is slightly different to your 
makefile:

CC              =       icc
CXX             =       icc
FLAGS           +=      # -DROUNDING_FE
OFLAGS          +=      -g -mp -w2 -wd279,383,444,810,981 #-Xc
CFLAGS          +=
CXXFLAGS        +=
ARFLAGS         =       crs
LDFLAGS         +=
ZLIB_FLAGS      =
ZLIB_LDFLAGS    =       -lz
READLINE_FLAGS  =
READLINE_LDFLAGS=       -lreadline

I don't know what the parameters mean for the intel compiler, but one of the main differences is 
that there is no -lstdc++ and no -static in the LDFLAGS.

Here are the flags of Soplex' make.linux.x86.intel.opt.static. Probably, some combination of these 
flags will do the job.

CXX     =       icc
CPPFLAGS=       -Isrc -DNDEBUG -DNO_ADDITIONAL_CHECKS -DWITH_ZLIB
CXXFLAGS=       -O3 -tpp6 -axK -ansi -w1 -fno-rtti -par_report0 -vec_report0 -ip
LDFLAGS =       -lpthread -lz -lm -lstdc++ -static
ARFLAGS =       crs


The problem can also be the fact that SCIP is a C library while Soplex is C++. Maybe, the compiler 
messes namespaces up or you need an additional flag for this...

Best, Tobias
