Installation Instructions for Ragout


Ragout is available for Mac OS and Linux.

Build Requirements

  • C++ compiler with C++0x support (GCC 4.6+ / Clang 3.2+ / Apple Clang 4.2+)
  • GNU make / Cmake (for building Sibelia)

Runtime Depenencies

Binary Distribution

Pre-compiled binaries are available for Linux and Mac OS from the releases page [https://github.com/fenderglass/Ragout/releases]. In this case you will not need the installation procedures below.


To build Ragout native modules, type:


You will also need either Sibelia or HAL tools installed (see below)


To build and install Sibelia, use:

    python scripts/install-sibelia.py

If you already have Sieblia installed into your system, it will be picked up automatically by Ragout.

HAL Tools

HAL alignment produced by Progressive Cactus could be used for synteny blocks decomposition instead of Sibelia (recommended for large genomes). If you want to use HAL alignment as input, you need to install HAL Tools package [https://github.com/glennhickey/hal] as it is described in the manual. Do not forget to properly set PATH and PYTHONPATH environment variables.


Q: Many compilation errors, possibly with “unrecognized command line option ‘-std=c++0x’” message:

A: Probably your compiler is too old and does not support C++0x. Minimum required versions of GCC and Clang are given in the beginning of this document.

Q: “libstdc++.so.6: version `CXXABI_1.3.5’ not found” or similar error when running

A: Ensure that the version of libc++ that was used to compile Ragout is similar to one the you currently using. You can specify an extra search path to a specific library by setting “LD_LIBRARY_PATH” variable.
