I had just download the gpc-20010409 package, and followed the instructions to build it and installed. All things looks like well, but I can't debug any program, even like this:
------------------------------------------------------------- program hello;
begin writeln('Hello world'); end. -------------------------------------------------------------
I compiled it with `gpc -g -o hello hello.pas', and then issue `gdb hello'. The following is the output from gdb.

I'm using a TurboLinux chinese version 6.0, with gcc-2.95.2, binutils 2.9.1.0.25. I also tryed with gcc-2.95.3, gpc-2001331 but failed too. But when I got the suse's version `gpc.rpm' and installed it, move `/usr/lib/gcc-lib/i486-suse-linux/2.95.2/*' to `/usr/lib/gcc-lib/i586-pc-linux/2.95.2/' and change `/usr/lib/gcc-lib/i486-suse-linux/2.95.2' to be a symbolic link. It does work!
Why?

The problem is that startup of Pascal programs is a little different from C (because there are explicit and automatic initializers etc.). Try the following instructions (you can put them in your .gdbinit). Then `l' should work. (Note, they may change in some future GPC version ...)
break init_pascal_main_program run break pascal_main_program break '_p_runfinalizers' cont
