When using WSL (Windows Subsytem for Linux)

  • If the repo is cloned in Windows and used in the Linux environment, shell scripts will have CRLF line endings and will need to be converted to work.
  • A strange bug was seen that caused the vw_jni target to fail to build. A full fix isn't known but the following were factors:
    • CMake version 3.5.1
    • WSL Ubuntu 16.04
    • Java was installed in Windows and added to the Windows path when compiling vw_jni
    • Setting JAVA_HOME caused CMake to display the right dependency at configure time but the Windows files were actually used
