Known issues

• 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
