Hi all,

I am triing to install abinit-6.10.3 on ubuntu server 11.10. I prepared ubuntu.ac

Code: Select all

prefix="/usr/local"
enable_mpi="yes"
enable_mpi_io="yes"
with_mpi_prefix="/usr"
with_netcdf_incs="-I/usr/include"
with_netcdf_libs="-L/usr/lib -lnetcdf -lnetcdff"
with_fft_flavor="fftw3"
with_fft_incs="-I/usr/include/"
with_fft_libs="-L/usr/lib -lfftw3"
with_linalg_flavor="atlas"
with_linalg_libs="-L/usr/lib -llapack -lf77blas -lcblas -latlas"
with_dft_flavor="atompaw+bigdft+libxc+wannier90"
enable_gw_dpc="yes"
enable_maintainer_checks="no"
enable_test_timeout="yes"
enable_gui_build="no"


and run ./configure --with-config-file="./ubuntu.ac"

Code: Select all

==============================================================================
 === Final remarks                                                          ===
 ==============================================================================


Summary of important options:

  * C compiler      : gnu version 4.6
  * Fortran compiler: gnu version 4.6
  * architecture    : intel xeon (64 bits)

  * debugging       : basic
  * optimizations   : standard

  * MPI    enabled  : yes
  * MPI-IO enabled  : yes
  * GPU    enabled  : no (none)

  * TRIO   flavor = netcdf+etsf_io
  * TIMER  flavor = abinit (libs: ignored)
  * LINALG flavor = atlas (libs: user-defined)
  * FFT    flavor = fftw3 (libs: user-defined)
  * MATH   flavor = none (libs: ignored)
  * DFT    flavor = libxc-fallback+atompaw-fallback+bigdft-fallback+wannier90-fallback

Configuration complete.
You may now type "make" to build ABINIT.
(or, on a SMP machine, "make mj4", or "make multi multi_nprocs=<n>")


make -mj4 abinit, i find this message :

The problem was solved by adding -lgomp in with_fft_libs="-L/usr/lib -lfftw3"
