Building JSCIPOpt on Linux

You need to download the following software packages to use/extend the Java interface:

  • SCIP Optimization Suite
  • Java JDK
  • C compiler
  • CMake
  • SWIG (optional)

The following steps need to be done before compiling the Java interface.

  1. Create a shared library of the SCIP Optimization Suite by executing
   mkdir build
   cd build
   cmake ..
   make

in the SCIP Optimization Suite directory. This should have created all necessary libraries.

2a) Building JSCIPOpt on Linux.

Compile the interface by executing the following commands:

   mkdir build
   cd build
   cmake .. -DSCIP_DIR=<absolute path to SCIP Optimization Suite>/build
   make

Execute the examples via

   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.
   cd Release
   java -cp scip.jar:examples.jar <"Linear" or "Quadratic" or "Read" or "Multiknapsack">

2b) Building JSCIPOpt on Windows.

Compile the interface by executing the following commands:

   mkdir build
   cd build
   cmake .. -G "Visual Studio 14 2015 Win64" -DSCIP_DIR=<absolute path to SCIP Optimization Suite>/build
   cmake --build . --config <"Release" or "Debug">

Execute the examples via

    export PATH=$PATH:<absolute path to SCIP Optimization Suite>/build/bin/{Release,Debug}
    cd Release
    java -cp "scip.jar;examples.jar" <"Linear" or "Quadratic" or "Read" or "Multiknapsack">

Please note that the first command makes sure that java is finding the scip.dll of the SCIP Optimization Suite. Alternatively, it would be possible to copy the scip.dll next to jscip.dll in the Release (or Debug) directory.
