C -> Java

Imam C projekt, kateri zeli komunicirati z Javo. Ampak, ko pozenem java program z popen() imam probleme, saj je Java program narejen z Intellij, kjer mam lepo vkljucene kot module vse potrebne jar-e in podobno. Poskusil sem program zagnati tako, da sem prekopiral kar direktno komando, ki jo pozene IntelliJ

Komunikacija potem deluje, ampak ko pride do uporabe funkcij iz vkljucenih jarov se vse podre:

N = 0, r=10 -> communication succsesfull
Exception in thread "main" java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path

Da bi pognal C program iz Jave bi bilo se tezje, saj C vkljucuje knjiznjivo MPI (to je treba klicat na nek svoj nacin spet...).

Ce kdo zna tole resit, bi blo super.

Ne gre za jar ampak za kaksen DLL. Verjetno tale tvoj java program uporablja kak DLL preko JNI.
