"minimal" test case: |
| 48 |
|
provide an example of a minimal set-up which only compiles eesupp/src |
| 49 |
|
and the 2 pkgs (exch2 & debug) which don't need model/src & inc. |
| 50 |
|
|
| 51 |
|
code_min: |
| 52 |
|
CPP_OPTIONS.h (standard version, needed here since model/inc is not linked) |
| 53 |
|
packages.conf (2 pkgs: exch2 & debug) |
| 54 |
|
main.F (copied from eesupp/src, but skip the call to THE_MODEL_MAIN) |
| 55 |
|
SIZE.h (same as code/SIZE.h) |
| 56 |
|
SIZE.h_mpi (same as code/SIZE.h_mpi) |
| 57 |
|
|
| 58 |
|
input_min |
| 59 |
|
eedataa (standard version) |
| 60 |
|
eedata.mth (to test running 2 threads) |
| 61 |
|
data.exch2.mpi (to test blank-tiles with exch2 and MPI built) |
| 62 |
|
|
| 63 |
|
to build: |
| 64 |
|
in order not to compile model/src, need to: |
| 65 |
|
either put (in build dir) a "genmake_local" file: |
| 66 |
|
% cat > genmake_local <<EOF |
| 67 |
|
STANDARDDIRS="eesupp" |
| 68 |
|
EOF |
| 69 |
|
- or - |
| 70 |
|
use genmake2 command line: "genmake2 -standarddirs eesupp -mods ../code_min" |
