Package: spectools Version: 200902R1-2 Tags: patch Hi Michael,
version 2009-02-R1 of spectools didn't work correctly with my
`wi-spy 2.4x': The GTK frontend was stuck in the `calibrating device'
phase while spectools_raw printed one line of data and then just sat
there doing nothing.
I found that the attached patch fixes the problem for me. It reverts a
change introduced between 2007-10-R2 and 2009-02-R1 (initialization of
some struct members got commented out) and adds a `memset' to make sure
memory is initialized before reading from it.
The problem exists in the current SVN version, revision 2789.
Version in the Debian package, package version 200902R1-2, suffers from
the same problem. I did not try the Lenny package, package version
200710R2-2. A bug report has been opened with this email.
If you need further information, please don't hesitate to contact me.
Thank you for spectools :)
Regards,
-octo
P. S.: I don't know of any mailing list to contact. If there is one,
