Re: [Help-glpk] [Fwd: Need help running GLPK code in Ubuntu server]

[Kazi Moyeen ul Huq]

Hi, 

The 1 & 2 issue in the previous mail is now solved.

But I still have the 3rd problem. For some reason it can't load the dynamic library during runtime. Any suggestion for that ?  

I'm using the following command to run the executable jar file ( it works in the latest version of Ubuntu)

java -Djava.library.path=/usr/lib/jni -jar st.jar

Thanks 

Kazi

The dynamic link library for GLPK for Java could not be loaded.

Consider using

java -Djava.library.path=

Exception in thread "Timer-0" java.lang.UnsatisfiedLinkError: no glpk_java in java.library.path

at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1681)

Hello Kazi,

in the description on
http://glpk-java.sourceforge.net/gettingStarted.html
I forgot the following step after installation of GLPK.

sudo ldconfig

Best regards

this point) :

3. when I tried to test run my program, I got the following error :
