on OSX I am unable to run a CP java program that I build successfully in IntelliJ IDEA

 

when I execute I get errors:

as you can see libcp_wrap_cpp_java1263.jnilib  is in my java.library.path folder just beside cplex and windows libraries

j1014741MBP:libs marcbrisson$ pwd

/Users/marcbrisson/dev/optimization/OptimizationLibrary/libs

j1014741MBP:libs marcbrisson$ ls

ILOG.CP.dll            cplex1263.dll            libcplex1263.jnilib

cp_wrap_cpp_java1263.dll    libcp_wrap_cpp_java1263.jnilib    ojdbc7.jar

 

this is frustrating because I have the exact same configuration for CPLEX and it runs without any issues.

any ideas?

 

Thanks

Hello Marc,

Did you check your DYLD_LIBRARY_PATH?
You might have a look at

here and here

I hope that helps,

Chris.

Hi 

DYLD_LIBRARY_PATH  was in fact the issue.  Surprisingly on OSX  setting this variable a value doesn't necessarily  propagate in the terminal.  Maybe a problem with SIP.

now CPLEX doesn't need DYLD_LIBRARY_PATH. It works simply with -Djava.library.path .  At some point cp and cplex should be package the same way.

Hi,

I'm struggling with the same issue. 

I followed the instructions about "Configuring the Eclipse Java IDE to use CPLEX libraries"( the below link). And I can run example java program.

http://www-01.ibm.com/support/docview.wss?uid=swg21449776

 

 But when I tried to use cp optimizer, i.e. IloCP cp = new ilog.cp.IloCP(); , I got the same error as yours:

Native code library failed to load: ensure the appropriate library (opl1271.dll/.so) is in your path.

Exceptions:

no opl1271 in java.library.path

no opl_lang_wrap_cpp in java.library.path

no cp_oaas1271 in java.library.path

no cp_oaas in java.library.path

  Reason: image not found

no cp_wrap_cpp in java.library.path

no concert_wrap_cpp_java1271 in java.library.path

no concert_wrap_cpp in java.library.path

 

I set up the env variables:

export CLASSPATH=$CLASSPATH:(my_path)/CPLEX_Studio1271/cpoptimizer/lib/ILOG.CP.jar

export LIBRARYPATH=$LIBRARYPATH:(my_path)/CPLEX_Studio1271/cplex/bin/x86-64_osx/:(my_path)/CPLEX_Studio1271/cpoptimizer/bin/x86-64_osx/

export DYLD_LIBRARY_PATH=(my_path)/CPLEX_Studio1271/cplex/bin/x86-64_osx/:(my_path)/CPLEX_Studio1271/cpoptimizer/bin/x86-64_osx/

But the error is not fixed.

I can use CP optimizer on eclipse now, according to https://www.ibm.com/developerworks/community/forums/html/topic?id=83b7da44-14cd-4949-93fd-b968945cd7e0&ps=25

 

It set DYLD_LIBRARY_PATH in eclipse --> run configuration --> environment with appropriate path.

 

Besides, I don't understand why "set DYLD_LIBRARY_PATH via export" does not work when run java program in command line.
