Greetings,
There's a bug in the VMS build procedure for the just-released netCDF 2.3
package. The C preprocessor macro SWAP must be defined when building the
implementation -- but it isn't. As a consequence, bytes from multi-byte
variables are written to netCDF files in the wrong order. You can see this
by dumping the first block of a netCDF file created by the new release:
$ dump/byte/block=end:1 test.cdf
Dump of file TEST.CDF;1 on 4-MAY-1993 15:24:17.41
File ID (4616,14,0) End of file block 15 / Allocated 15
Virtual block number 1 (00000001), 512 (0200) bytes
00 00 00 03 00 00 00 0A 00 00 00 08 43 44 46 01 .FDC............ 000000
...
The initial sequence of characters should be `CDF.' rather than `.FCD'
(this sequence is a `magic cookie' and appears in all valid netCDF files
created by our implementation of the netCDF specification).
The solution is to rebuild the package after adding the string
`/define=swap' to the definition of `ccc' in the file [.libsrc]make.com,
i.e. in the specified file, change
$ ccc := cc /opt/nodebug/include=([-.xdr])/nolist/define=stdc_includes
to
$ ccc := cc
/opt/nodebug/include=([-.xdr])/nolist/define=stdc_includes/define=swap
I apologize for any inconvenience this might cause.
Regards,
Steve Emmerson
