Я пытаюсь использовать SCIP JNI с помощью SCIP Optimization Suite и компилирую его из исходного кода с помощью Ubuntu 16.04. Я скомпилировал папку интерфейса jni, используя инструкции, представленные на сайте, но, похоже, возникла проблема с примером JniKnapsack. При запуске с помощью Makefile и файла run.sh, доступного в папке:
make run
Результат:
SCIP version 3.2.1 [precision: 8 byte] [memory: block] [mode: optimized] [LP solver: SoPlex 2.2.1] [GitHash: c7c6c02]
