Test failure, table not found B0000000000000013000.TXT and not included with bufrdc_tables.zip #24

Closed gerritholl closed 5 years ago

gerritholl commented 5 years ago

Running the bufrtables unittests, the code tries to read test/bufrtables/B0000000000000013000.TXT. I have unzipped bufrdc_tables.zip, which includes B0000000000000026000.TXT but not B0000000000000013000.TXT. Apparently the mver (inferred from the file contents?) for the test file is 13 but this file is not included with the distribution.

When I copy the relevant file from python-bufr then the test does not fail at the same point (rather, it fails at test_bufr_read, see #25).

Unpacking the ZIP-archive 'bufrdc_tables.zip' -- which was packed by ECMWF -- requires running the shell-script 'links.sh' (from that archive) to create links for all table files, including 'B0000000000000013000.TXT' you missed.
