Cygwin is still a beta release (20.1, as of Dec 4, 1998) and there are known
problems; please refer to the Cygnus documentation page for
these. As for GMT, our preliminary testing under Win95 has
revealed teh following:
- The I/O redirection seems to have problems when binary
i/o is selected. This is likely to be related to the fact that
on MS-DOS machines there are both text and binary modes for
opening files, but redirection only uses text mode. Thus,
when GMT writes binary to standard out there seems to be some
contamination with CR/LFs. The workaround on WIN32 platforms is
to use the WIN32-specific extension to the -b option:
You may append a comma followed by the output file name for the
binary data. This redirects the output to that file using
binary mode. For example, using -–bod:junk.b writes to
junk.b. Note this option is only available when
GMT is compiled under Windows.
