configure --prefix=/usr, and it will then install the gFTP binary to
/usr/bin/gftp.</P

<A

>1.5. How do I report bugs in gFTP?</A
></H2
><P
>If you find ANY bugs in gFTP, please check to make sure that you are using
the latest version of gFTP. If you are, please submit all bug reports to
GNOME's Bugzilla. When sending in bug reports, please try to be as
descriptive as possible. Send me what OS/version you are running, what
compiler you are compiling with, the output of <SPAN
CLASS="emphasis"
><I
CLASS="EMPHASIS"
>gftp --info</I
></SPAN
>
and any other important information. If you get gFTP to crash, it would be very
helpful if you could send me a backtrace. If you do not know how to do a
backtrace, download the source code from my website. Edit the Makefile, and
make sure that -g appears in the CFLAGS variable. Then recompile gFTP, but do
NOT run make install because it will install a stripped binary in $PREFIX/bin.
Then type gdb ./gftp. Once you have a (gdb) prompt, type r. When gFTP crashes,
go back to that terminal window, and type bt, and put that output in the bug
that you file with bugzilla.</P
><P
>I also have a gftp-users mailinglist setup. I have a link to the archives
on my main webpage. If it is strictly a bug report, please submit it to
Bugzilla instead of the mailinglist. Bugs that are submitted to bugzilla are
much easier for me to track.</P
><P
>Also, if you do not get a response back from me immediately, that is not
uncommon. I usually stay very busy and I don't get to work on gFTP all of the
time.</P

you can run the gftp-gtk. The gftp command is just a shell script that checks
if your DISPLAY variable is set, and if so it'll run the appropriate version.</P
