Hi,

I just installed the CPLEX_stupio1251 in order to use cpoptimizer.

I am currently trying to get running the code given as example for a RCPSP problem.

Using java, I built a new project with the file given :  CPLEX_Studio1251/cpoptimizer/examples/src/java/SchedRCPSP

then added the jar: CPLEX_Studio1251/cpoptimizer/lib/ILOG.CP.jar

But I do get the error: "

Native code library failed to load: ensure the appropriate library (opl1251.dll/.so) is in your path.

Exceptions:

no opl1251 in java.library.path

no opl_lang_wrap_cpp in java.library.path

...

"

From my search I need to add a native library from opl .....

but the thing is that I am a mac user, and opl is not compatible http://pic.dhe.ibm.com/infocenter/prodguid/v1r0/clarity-reports/report/html/softwareReqsForProduct?deliverableId=1357752720677&osPlatform=Mac%20OS

What I am missing ?

Regards,

Alban.

Dear Alban,

What version of MacOS X are you using?

Also, please run  the CP optimizer java examples installed in <installdir>/cpoptimizer/examples/src/java. They should function correctly when you execute them using the makefile in <installdir>/cpoptimizer/examples/<platform>/<arch>.

Looking at env variables used in the makefile, we can see directives as:CPCLASSPATH = ../../../lib/ILOG.CP.jar
LIBRARYPATH = ../../../bin/x86-64_osx:$(CPLEXDIR)/bin/x86-64_osx
JAVAEXDIR = ../../../examples/src/java
    @echo "Currently, JAVA_HOME = $(JAVA_HOME)"
    DYLD_LIBRARY_PATH=$(LIBRARYPATH):$$DYLD_LIBRARY_PATH $(JAVA) $(JAVAFLAGS) -classpath $(CPCLASSPATH):. Color

So please make sure that the correct DYLD_LIBRARY_PATH is set when invoking your example.

I hope this helps,

Cheers,

Hi, I have the same problem as the original poster, and rdumeur's solution didn't help.  I can compile and run the example CP files using the makefile included with the distribution, but I can't run any CP code from Eclipse using MacOS.  I've set the DYLD_LIBRARY_PATH variable, to no avail.  Any suggestions?
