UnifyFS Dependencies

Required

• Automake version 1.15 (or later)

• GOTCHA version 1.0.4 (or later)

• Margo version 0.13.1 and its dependencies:

  • Argobots version 1.1 (or later)

  • Mercury version 2.2.0 (or later)

    • libfabric (avoid versions 1.13 and 1.13.1) or bmi

  • JSON-C

• OpenSSL

Important

Margo uses pkg-config to ensure it compiles and links correctly with all of its dependencies’ libraries. When building manually, you’ll need to set the PKG_CONFIG_PATH environment variable to include the paths of the directories containing the .pc files for Margo, Mercury, Argobots, and OpenSSL.

Optional

• spath for normalizing relative paths
