The Yambo source code can be downloaded from several sources. Refer to the dedicated page for further informations.

Configuration (quick)

Yambo can make good use of external libraries like FFTW, ESSL, BLAS, netCDF, HDF5, and so on. It is worth identifying if they are already installed on your system, especially for HPCs.

If you are lucky, the configure script will successfully find the best compiler options.

% tar -xvzf yambo-latest.tar.gz
% cd yambo-X.X.X
% ./configure
% make core

Executables are found in the bin folder. To check that it works:

% ./bin/yambo

Cannot access CORE database (SAVE/*db1 and/or SAVE/*wf)

Configuration (full)

In general, however, some fine-tuning will be necessary to link the requested libraries.

./configure --help

After configure, you can also edit the config/setup file.

If you want to install yambo on your local machine or just for testing/tutorial purposes, you can start with the configure options suggested here.

Specific Configuration options

Her is a list of specific configuration options.

* Configure options for yambo 5.0 
* Configure options for Yambo 4.4.0
* Configure options for Yambo v4 and v3

Known Issues

  • gfortran 4.4 or earlier versions
    Yambo 5.x uses different Fortran constructs, as for example "allocate(x, source=y)", that are not supported by gfortran 4.4 and its earlier versions, please update your gfortran or use a different compiler.
  • NetCDF/HDF5 in Ubuntu 20.4
    Internal NetCDF and HDF5 libraries in LinuxMint 20.1/Ubuntu 20.4 have problems with Yambo please use internal Yambo libraries
  • Quantum-Espresso at GAMMA point
    In Quantum-Espresso if you perform a SCF calculation using the option "KPOINTS gamma" you should use the same option for the NSCF otherwise Yambo gets confused with the g-vectors. If you need more k-points in the NSCF just re-run the SCF with "KPOINTS automatic /1 1 1 0 0 0" and the run NSCF with a finite k-grid
  • Internal MAC-OSX libraries
    At present it is no possible to compile Yambo with internal macos libraries Indeed, no include/system/netcdf.mod file is present in the system. The problem is due to Autoconf setting which automatically searches for versions of the needed libraries in your system despite the specific options given to configure. Then, it would compile the internal hdf5, then find an external netcdf, then try to compile netcdf-fortran creating various conflicts.
  • gfortran compiler on MAC-OSX
    There are different problems compiling Yambo with "gfortran" variant of the compiler/libraries with MacPorts, a possible solution it is to install the "gcc8" variant of these libraries and compilters.
    More details here:
  • Input file generation on MacOSX
    There are two issues on input file generation: 1) when you generate an input file on MacOSX Yambo is not able to read values already present in the input file, and reset them to the default value; 2) if yambo and ypp have the same option to generate an input file the code get confused. Please use long input strings, for example "yambo -optics" instead of "yambo -o".
