#To get valgrind output with suppressed errors

(for instance with command besstandalone -c tests/bes.conf -i tests/contiguous/coads_climatology.dmr in dmrpp-module):

1. Generate valgrind output

####(vg-dmrpp.txt)

cd ../hyrax/bes/modules/dmrpp-module

valgrind --leak-check=full --show-reachable=yes --error-limit=no --gen-suppressions=all --log-file=vg-dmrpp.txt besstandalone -c tests/bes.conf -i tests/contiguous/coads_climatology.dmr

If in the log file you get "Warning: client switching stacks?..." then use --max-stackframe option to get clean output.

2. Get suppression file

####(vg-dmrpp.supp)

cat vg-dmrpp.txt | /home/opendap/hyrax/bes/parse_valgrind_suppressions.sh > vg-dmrpp.supp

3. Get valgrind output with suppression file

valgrind -s --leak-check=full --show-reachable=yes --error-limit=no --suppressions=./vg-dmrpp.supp --gen-suppressions=all --log-file=test_bes_make.log besstandalone -c tests/bes.conf -i tests/contiguous/coads_climatology.dmr

Suppression file could be edited to remove repeated lines that catches multiple similar errors.
