Question

我正在尝试将GLPK用于我的Java项目。我按照此处https://wiki.nps.edu/pages/viewpage.action?pageId=113606659的链接安装和配置Java的GLPK。在Java项目中，我使用了

compile 'org.gnu.glpk:glpk-java:1.12.0'

包括glpk java项目。另外，我将jar glpk-java-1.12.0.jar复制到了项目lib文件夹中，该文件由gradle包含为

flatDir {
   dirs 'lib'
}

下面是我的测试代码

public class ILPTest {
    @SuppressWarnings({ "rawtypes", "unchecked"})
    public static void main(String[] args) {
        testGLPK();
    }

    private static void testGLPK() {
        System.out.println(GLPK.glp_version());
    }
}

但是，当我运行它时，出现以下错误

The dynamic link library for GLPK for Java could not be loaded.
Consider using
java -Djava.library.path=
The current value of system property java.library.path is:
/Users/heya/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:.

        at com.ILPTest.testGLPK(ILPTest.java:46)
        at com.ILPTest.main(ILPTest.java:36)

我在这里想念什么？请帮忙。

Answer 1

在IntelliJ中配置-Djava.library.path=/usr/local/lib/jni之后，它可以正常工作。

无法加载用于Java的GLPK的动态链接库
