It's going to take quite a while. I'll report back when it's done. tester@gentoo.org 2004-11-06 21:10:06 0000 I can't find lazarus or tct in portage.. what package is this bug against? gentoo.bugzilla@figmental.net 2004-11-06 23:35:02 0000 The coroners toolkit: app-forensics/tct masked by keyword ~x86 lazarus is a tool provided in this package. BTW, it worked like a champ with the workaround in place. Not sure what other tools might be broken by the missing /usr/lib/tct/etc files. I'll using it a lot over the next week on a forensics project for school, so if I find any others, I'll post them. ka0ttic@gentoo.org 2004-11-07 01:49:15 0000 The problem was that I missed the $magic_file variable in lazarus, when creating the gentoo patch. I have committed 1.15-r1 with an updated patch. Please test and verify that it solves the problem and let me know. Thanks. gentoo.bugzilla@figmental.net 2004-11-09 17:06:19 0000 Created an attachment (id=43631) Fixed missing semicolon in magic block. Line 92 of /usr/lib/tct/bin/lazarus was missing a semicolon and produced the error: syntax error at /usr/sbin/lazarus line 92, near "die" Execution of /usr/sbin/lazarus aborted due to compilation errors. Added the semicolon as follows and it works fine: # # we usually carry around the alternate magic file... # $magic_file="/usr/share/misc/file/magic"; die "Can't find $magic_file\n" unless (-f $magic_file); Excuse my ignorance as to the process of submitting patches. I hope this is OK. I fixed the tct-1.15-r1-gentoo.diff, rebuilt the digest, and re-emerged. Works fine. The updated diff is attached ka0ttic@gentoo.org 2004-11-10 05:30:04 0000 Usually diffs are the way to go. For 1 byte though, it's probably a little overboard ;) Anyways, I just fixed the patch.
