Thanks a lot, it worked! I was passing the library path as a parameter to
the jvm but that was not enough.
Now it all works well when I run my program from ant but It crashes if I run
it from the Netbeans platform. Does anyone know why this error might come
up?
java.lang.UnsatisfiedLinkError: org.gnu.glpk.GLPKJNI.glp_create_prob()J
at org.gnu.glpk.GLPKJNI.glp_create_prob(Native Method)
at org.gnu.glpk.GLPK.glp_create_prob(GLPK.java:47)
Thanks in advance,
Alberto
