Last change on this file since 2509 was 2509, checked in by Laurent Fairhead, 8 years ago

Modifications for the XIOS 2 I/O library

LMDZ will now, by default, use the XIOS 2 library. If you need/want to link LMDZ
with the XIOS 1 library you will need to add the XIOS1 cpp key to your compilation thus:

makelmdz_fcm -d ... -cpp XIOS1 ... gcm

and then use the XIOS1 xml files for LMDZ that are in LMDZ/DefLists:

DefLists?/iodef_XIOS1.0.xml
DefLists?/context_lmdz_XIOS1.0.xml

as there are some incompatibilities between XIOS 1 and XIOS 2.
