[SCIP] Auto-discard notification

Hi Benjamin,
Is there an easy solution if one would like to use CPLEX (64-bit version) instead of SoPlex as an LP solver together with Visual Studio on windows? I followed the instructions provided in the INSTALL file and also have skimmed through lots of posts, but did not manage to get it working.
Can MinGW, which compiles and links code to be run on Win32 platforms, actually be used for that purpose?
When compiling SCIP, it asks for "soft-links" to CPLEX. How should it look like in case of CPLEX (64-bit) on windows (there is only a cplexXXXX.lib file)?
Thanks,
David

Hi Sujayandra,
yes, it is. I always use Msys (http://www.mingw.org/wiki/MSYS) for this and call the VS compiler directly to compile SoPlex and SCIP. It is actually not too complicated. First you need to add (something like)
call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64\vcvars64.bat"
to the first line of the batch file of msys. Then compile SoPlex and SCIP with:
make ARCH=x86_64 COMP=msvc OPENSOURCE=false
That is it! Let us know when something did not work.
Regards,
Benjamin
