Hello,

I am trying to use the Gurobi java API for the first time and I am trying to run the MIP1 example here: https://www.gurobi.com/documentation/9.1/examples/mip1_java.html

I am using IntelliJ IDEA on Linux Ubuntu machine. I imported gurobi module to IntelliJ and the program build was done without errors. But when I try to run it, I get the following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/ramy/gurobi950/linux64/lib/libGurobiJni95.so: libgurobi95.so: cannot open shared object file: No such file or directory

at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1850)
at java.lang.Runtime.loadLibrary0(Runtime.java:871)
at java.lang.System.loadLibrary(System.java:1124)

at gurobi.GRBEnv.<init>(GRBEnv.java:107)
at com.example.java.Main.main(Main.java:20)

Process finished with exit code 1

I would be very grateful to get your help in this regards

 

Regards

Ramy

  This question is also handled on StackOverflow: linux - Problem with Gurobi java API: libgurobi95.so: cannot open shared object file: No such file or directory - Stack Overflow

  summary: It's most likely an issue with the Java compiler environment not loading the runtime library specified in the environment variable LD_LIBRARY_PATH.
