On a recently installed Gentoo 2004.1 box, my ufed began to malfunction with the following error, Nested quantifiers in regex; marked by <-- HERE in m/ ** <-- HERE * err [lib/liblow.c(329)]: / at /usr/sbin/ufed line 570. Problem is that ncurses was linked against gpm. gpm was not in use/had not been setup. Attempts by ncurses to use gpm were sending messages to stderr which is also the discriptor that dialog spits out its results. So gpm's errors were embedded in dialog's stderr output (ie the flags listing). Solution was to open a file descriptor and have dialog dump its results to that file descriptor instead of stderr. ufed was modified to load its tempfile from that new discriptor instead of stderr. Major credit goes to Kevin Bryan for the file descriptor magick. Here is the patch to ufed. --- ufed.pl 2004-05-21 20:53:12.000000000 +0000 +++ ufed.pl 2004-05-21 20:54:12.000000000 +0000 @@ -284,8 +284,8 @@ $items .= '"' . %use_desc_flags->{$flag} .

So here's one ncurses+gpm problem fixed. Enjoy. Brandon Edens Reproducible: Didn't try Steps to Reproduce: 1. Build ncurses with gpm support 2. disable gpm 3. execute ufed 4. Make changes to flags 5.
