UnifyFS Dependencies

Required

• Automake version 1.15 (or later)
• GOTCHA version 1.0.3 (or later)
• Margo version 0.9.6 and its dependencies:
  • Argobots version 1.1 (or later)
  • Mercury version 2.0.1 (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 Mercury, Argobots, and Margo.

Optional

• spath for normalizing relative paths
