Required packages

Regardless of operating system, Jep requires compatible versions of the JDK and Python to be installed before it can be built and run. Here are some frequently used package names:

CentOS/RHEL

• JDK
  • java-1.6.0-openjdk-devel
  • java-1.7.0-openjdk-devel
  • java-1.8.0-openjdk-devel
  • Oracle JDK
• Python
  • python-devel

Ubuntu/Debian

• JDK
  • openjdk-6-jdk
  • openjdk-7-jdk
  • openjdk-8-jdk
  • Oracle JDK
• Python
  • python-dev
  • python3-dev

LD_PRELOAD

Due to some (common) difficulties with Java and C projects that dlopen libraries, you may need to set the LD_PRELOAD environment variable. That's in addition to setting LD_LIBRARY_PATH if you've installed libjep into a directory not cached by ld.so. See the contents of the installed jep script for an example how to do this. The script should have the correct values for your interpreter and virtualenv (if present).

LD_PRELOAD only applies to *nix systems, not Windows or OS X. It may or may not be required depending on your *nix system and environment.
