Why am I getting this error when trying to open a file with DDD?

Question

Debugger: DDD.

64-bit Ubuntu Precise Pangolin system.

Whenever I try to open a very simple C program in ddd I get the following error:

Warning: This program is an suid-root program or is being run by the root user.
The full text of the error or warning message cannot be safely formatted
in this environment. You may get a more descriptive message by running the
program as a non-root user or by removing the suid bit on the executable.
Warning: Cannot convert string "%s" to type %s

Warning: Could not load font "-*-lucidatypewriter-medium-r-*-*-*-120-*-*-*-*-iso8859-*", using font "fixed" instead

Also, ddd opens up fine after all these errors get displayed on the terminal, but without the source file I want to debug. I can't find an solution to this online! Thanks.

EDIT:

I get the above error when running as root. I get the following when running as a normal user:

...and the output of `whoami`? (since it looks like you try to run ddd as root which is probably not what you want) — Fredrik Pihl, Feb 02 '13 at 17:50
I'm running as root. I tried running as a normal user but I get the same problem, though not the suid-bit part. — amorimluc, Feb 02 '13 at 17:51
You don't run `ddd` on the source, try `ddd a.out` (or whatever you called your executable). — Daniel Fischer, Feb 02 '13 at 18:45
I tried running it on my executable, but I still get the exact same error. — amorimluc, Feb 02 '13 at 18:50
see http://savannah.gnu.org/bugs/?30270 (and yes, I get the same printout) — Fredrik Pihl, Feb 02 '13 at 18:50
Hum. That bug was reported two years ago, is there a way to change DDD's config files to allow UTF-8? I don't know much about changing config files. And does that mean my code is using UTF-8 characters? — amorimluc, Feb 02 '13 at 18:55

I think I figured it out with the help of @Fredrik.

UTF-8 incompatibility seems to be a long-standing bug in ddd. Many people have reported it but no one seems to have fixed it yet.

The reason my code wasn't displaying in ddd was because I wasn't using the -g option when compiling.

Why am I getting this error when trying to open a file with DDD?
