Installation and Configuration Notes
All Platforms · Linux · Mac OS X · Windows

All Platforms
  • Please see the README.txt file in the .tar.gz package
     
  • If you encounter any problems or regressions, please report them
     
  • If you use Armadillo in your research and/or software, please cite the overview tech report. Citations are useful for the continued development and maintenance of the library.

Linux   (Fedora, Ubuntu, Red Hat, SUSE, Debian, etc)
  • Armadillo can work without external libraries. However, to get the most functionality it's recommended to install (in advance) the LAPACK, BLAS and ATLAS libraries, along with the corresponding development/header files.
     
  • For faster performance, instead of using standard BLAS we recommend using the multi-threaded OpenBLAS library
     
  • Many Linux-based operating systems provide pre-built Armadillo packages, eg. Fedora, Debian, Ubuntu, openSUSE, Arch. These packages may not be the latest version. If you're encountering problems, please use the official packages provided here.
     
  • Recommended packages for Fedora & Red Hat (installed before Armadillo): cmake, blas-devel, lapack-devel, arpack-devel, atlas-devel.
     
  • Recommended packages for Ubuntu & Debian (installed before Armadillo): cmake, libopenblas-dev, liblapack-dev, libarpack-dev.
     
  • If you're updating from a previous version, it's a good idea to remove all the old files before updating. The files are typically in /usr/include/armadillo* as well as the library files in /usr/lib/ or /usr/lib64/

Mac OS X
  • The "Accelerate" framework is used for accessing BLAS and LAPACK functions. See the README.txt file in the package for more information.
     
  • If you're updating from a previous version, it's a good idea to remove all the old files before updating. The files are typically in /usr/include/armadillo* or /usr/local/include/armadillo* as well as the library files in /usr/lib/ or /usr/local/lib/
