libgurobi65.so: cannot open shared object file, Linux, Ubuntu 16.04, Gurobi 651, Java

[Adrian Hasse]

hi,

this is not a question but a brief hint for people running Ubuntu and are confronted with this exception or similar errors:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/gurobi651/linux64/lib/libGurobiJni65.so: libgurobi65.so: cannot open shared object file: No such file or directory



Add a file randomLibs.conf to the directory /etc/ld.so.conf.d/

The file randomLibs.conf has to contain the following line(if you have another version than 651 you have to change the line accordingly):
/opt/gurobi651/linux64/lib/

After editing the file run the following command in the terminal:
sudo ldconfig

More detailed information here.



I hope this will save some time.

Adrian

Hey,

I just found another possibility (suggested here) were the following environment variables have to be set in the IDE (Eclipse, IntelliJ...):

GUROBI_HOME      = /opt/gurobi702/linux64/
GRB_LICENCE_FILE = /opt/gurobi702/linux64/gurobi.lic
LD_LIBRARY_PATH  = /opt/gurobi702/linux64/lib/
PATH             = /opt/gurobi702/linux64/bin/

The advantage is that no VM arguments and no additional config files are needed.
