Compile

The makefile automatically detects the hardware. However the FC environment variable should be set.

Modules:

Currently Loaded Modulefiles: 1) shared      2) proteus     3) gcc/4.8.1   4) sge/univa

Environment variable:

$ export FC=gfortran

Make

$ make >& Make.out &

Test

NB Seems to always fail with gcc 4.8.1

$ cd utest $ make

Install

$ make PREFIX=/mnt/HA/groups/myGrp install >& Make.install.out &

This creates the directories:

• ${PREFIX}/include -- containing the include files
• ${PREFIX}/lib -- containing the library (.a and .so) files
