[SCIP] [ITDS-Warning: SPAM] Building SCIP & MinIISC on Windows

[Andrea Gavana]

Hello SCIP Users,

I am a newbie with SCIP - I have used it a few times for simple MIPs and
always using the available binaries for Windows 64 bit. I have never
compiled it from source.

I am now looking for ways to detect IIS in some of my standard, continuous
LPs (no MIPs). My understanding is that the MinIISC application can be used
for that purpose.

Unfortunately, there appear not to be any precompiled binaries for MinIISC
(or any other application that is not SCIP). Or at least I couldn't find it
anywhere.

So I have tried to follow the instructions on building SCIP and MinIISC
from the SCIP website, using CMake on Windows and the MinGW64 toolchain
(gcc for Windows) 11.2.0. I explicitly specify MinGW Makefiles.

The CMake configure action ends like this:

The following OPTIONAL packages have been found:


* SOPLEX

* PkgConfig


-- The following REQUIRED packages have been found:


* Readline

* SCIP

* Threads

* ZLIB


-- The following OPTIONAL packages have not been found:


* Boost (required version >= 1.65.0)

* PAPILO

* ZIMPL (required version >= 3.5.0)

* IPOPT (required version >= 3.12.0)

* WORHP

* CRITERION

* GSL (required version >= 2.0)

* GMP

* CLIQUER


Configuring done


After the "generate" from CMake, I naively attempted this:

cmake.exe --build build --target miniisc

I get this:

C:\Users\XXXX\scipoptsuite-9.2.1\scip\src\scip\dialog.c:48:10: fatal error:
readline/readline.h: No such file or directory
   48 | #include <readline/readline.h>
      |          ^~~~~~~~~~~~~~~~~~~~~
compilation terminated.
mingw32-make[3]: *** [scip\src\CMakeFiles\libscip.dir\build.make:3751:

scip/applications/MinIISC/CMakeFiles/miniisc.dir/rule] Error 2
mingw32-make: *** [makefile:1022: miniisc] Error 2

I do have a readline-kind-of for Windows, that I obtained
from mingw-w64-x86_64-readline, but I guess I must be doing something wrong
somewhere. I am not an expert in compiling packages, so I am kind of lost
here.

I assume there aren't many people having a pre-compiled executable for
MinIISC on Windows, but if anyone does, please do let me know - I'd be
rather interested in giving it a try using some LP files I already
have. Or any other suggestion you may have to help me fix the build
issue would be most appreciated.


Thank you in advance.


Andrea.
