ddd Debugger

lmellen · 01-25-2004, 05:31 PM

I just started Sams Teach Yourself C for Linux Programming. I need something called a ddd Debugger. I went to the GNU web page but don't know what I'm looking at. I would like the debugger but am going to need somebody to walk me through the install. All help will be appreciated. I'm using slackware 9.1 and the vi editor. Thank you--lmellen

Data Display Debugger (ddd) is a graphical front end for gdb and other command line debuggers. Freshmeat.net has it. There should be directions that come with the package on how to install it. Most likely all you have to do is uncompress it (tar -xzvf packagename), configure it (./configure), make it (make), and then install it (su root, make install).

I'm about to start that book too! DDD 3.3.8 compiled just fine on my Slackware 9.1 box. Good luck to you in your endeavor.

I have ddd-3.3.8. tar.gz in my root directory.
I use tar -xzvf ddd-3.3.8.tar.gz to extract it.
I now have ddd-3.3.8.tar.gz & ddd-3.3.8/ in my root directory.
Next step is ./configure. Configure what? Everytime I try ./configure I get ddd... is a directory? I could use some more help! Thank you --Larry

go into the ddd-3.3.8 directory

type ./configure
if that doesn't have any errors type make
then type make install

You have to be root to do the make install part.

Jtshaw- Thanks for the assistance! ddd works fine!

Quick question-- I thought I had a problem, kept getting error message:
"Error: Can't open display. I've been working in text mode, at command
line. Tried ddd in terminal window in xwindows, worked fine.
Do you have to be in xwindows for ddd to work?
Again Thanks for the help!--Larry

Ya, you have to run the program as the user whom the x display belongs to. For instance, if I am logged into my machine as jshaw and I bring up a console in x and su to root I can't run graphical programs as root. But if I just open a console and run the program without suing to anyone else I can run it.
