This is just a test repo for jni

Currently tested:

  • Basic JNI
  • Access and use recsources from Java (variables and methods)
  • Modify resources in Java.
  • Combine with other self-built c libraries

Compile command (for window only):

  1. Install cygwin (Link: https://www.cygwin.com/)
  2. Add these 2 packages while installing: mingw64-x86_64-gcc-core for C and mingw64-x86_64-gcc-g++ for c++
  3. Open cygwin, move to the current project folder 3a. To make Hello.dll lib, use this command x86_64-w64-mingw32-gcc -I"%JAVA_HOME%\include" -I"%JAVA_HOME%\include\win32" -shared -o hello.dll HelloJNI.c 3b. To make Sort.dll, move to test folder and use this command x86_64-w64-mingw32-gcc -I"%JAVA_HOME%\include" -I"%JAVA_HOME%\include\win32" -shared -o Sort.dll Sort.c bbsort.c
