古罗比(Gurobi)UnsatisfiedLinkError [英] Gurobi UnsatisfiedLinkError

问题描述

我正在尝试根据Ubuntu 14.04上的学术许可证安装Gurobi.我已阅读有关 UnsatisfiedLinkError 的以下帖子:

I am trying to install Gurobi under Academic Licence on Ubuntu 14.04. I have read the following post about the UnsatisfiedLinkError: stackoverflow.com/questions/.... But that didnt help me. I have extracted the zip in my opt folder. I have placed the licence file in /opt/gurobi600/linux64/lib/gurobi.lic.

我正在尝试在Eclipse中运行 Callback.java 示例.

I am trying to run the Callback.java example in Eclipse.

我有一个Java VM参数: -Djava.library.path =/opt/gurobi600/linux64/lib/.我有作为程序参数:/opt/gurobi600/linux64/examples/data/qafiro.lp .环境变量 LD_LIBRARY_PATH 在/opt/gurobi600/linux64/lib/gurobi.lic

I have as Java VM argument: -Djava.library.path=/opt/gurobi600/linux64/lib/. I have as program argument: /opt/gurobi600/linux64/examples/data/qafiro.lp. The environment variable LD_LIBRARY_PATH is set on /opt/gurobi600/linux64/lib/gurobi.lic

我得到以下堆栈跟踪:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/gurobi600/linux64/lib/libGurobiJni60.so: libgurobi60.so: cannot open shared object file: No such file or directory

    at gurobi.GRBEnv.<init>(GRBEnv.java:11)
    at main.Callback.main(Callback.java:135)

有什么想法吗?

推荐答案

现在一切正常.我在运行配置菜单中删除了VM参数，因此在Eclipse中全部为空.我已经在Eclipse中更改了环境变量，现在将它们设置为:

It's all working properly now. I have removed the VM arguments in the run configurations menu, so that's all empty in Eclipse. I have changed the environment variables in Eclipse, they are now set to:

GUROBI_HOME      = /opt/gurobi600/linux64/
GRB_LICENSE_FILE = /opt/gurobi600/linux64/gurobi.lic
LD_LIBRARY_PATH  = /opt/gurobi600/linux64/lib/
PATH             = /opt/gurobi600/linux64/bin/
