# Tested with gcc-gfortran v4.0.x as shipped with Fedora Core 4. |
# Build options for gfortran compiler (GNU) on Linux AMD64 platform |
| 7 |
# It fixes the ' \' versus ' &' terminator problem but some |
# |
| 8 |
# namelist problems remain. The biggest seems to be the inability |
# Tested with gcc-gfortran v4.1.x as shipped with Fedora Core 6,7,8 |
| 9 |
# of current gfortran versions to support namelist syntax such as: |
# with gcc-gfortran v4.3.x as shipped with Fedora Core 9,10 |
| 10 |
# |
# |
| 11 |
# fields(1,1) = 'UVELSLT ','VVELSLT ','WVELSLT ', |
# OpenMP : Tested on dickens with gcc-gfortran v4.3.2 as shipped with FC 10 |
