8 years ago Dear Baohua,
today we investigated your issue and could run JSCIPopt on MacOS but the following steps were necessary. This is a temporary workaround and we will try to improve the Makefiles such that things should become much easier.
Apply the following steps to make the interface work on MacOS:
- apply the following patch to the
<SCIP directory>/Makefileof SCIP
diff --git a/Makefile b/Makefile
index d8e6f9a..1d0d987 100644
--- a/Makefile
+++ b/Makefile

make READLINE=false GMP=false ZLIB=false ZIMPL=falsein your SCIPOPTSUITE directory (not the SCIP one!) - go to the SCIP directory and call
make READLINE=false GMP=false ZLIB=false ZIMPL=false SHARED=true dll
this step creates a dll and puts it to your lib directory of SCIP. Copy this library to <JSCIPOpt>/lib.
cd <JSCIPOpt>/lib;ln -s <SCIP library>.dll <SCIP library>.dylibcd <JSCIPOpt>; make SCIPOPTLIB=<SCIP library> USRLDFLAGS=-dynamiclib SHAREDLIBEXT=dylib
Note that you need to remove the startin 'lib' and the ending '.dll' for SCIPOPTLIB=<SCIP library>.
cd <JSCIPOpt>/examples; ln -s ../lib lib; javac -cp ../lib/scip.jar *.java- and finally:
./run.sh Linear
Hope this works for now. The problem is that I do not have a Mac system and thus can not really work on this right now.
Please report any issue which might pop up.

Dear, I am happy to find this java interface for SCIP and cannot wait to try. I have successfully built the source code and got scip.jar and libjscipopt.so I am using IntelliJ Idea on Mac. What I do is: (1) add the ship.jar to dependency (2) add the ../lib directory to dependency (3) Run the Linear.java under /examples Unfortunately, I got following error: Exception in thread "main" java.lang.UnsatisfiedLinkError: no jscip in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1867) at java.lang.Runtime.loadLibrary0(Runtime.java:870) at java.lang.System.loadLibrary(System.java:1122) at com.amazon.etr.scip.Linear.main(Linear.java:11) It seems that IDE does not find libjscipopt.so in dependency…..But actually it is there. Did I forget something? baohua
