3.4 Debugging executables
Ifhellwas a complicated program, you would certainly want to test and debug it before installing it on your system. In the above section, you saw how the libtool wrapper script makes it possible to run the program directly, but unfortunately, this mechanism interferes with the debugger:
burger$ gdb hell

GDB 4.16 (i386-unknown-netbsd), (C) 1996 Free Software Foundation, Inc. "hell": not in executable format: File format not recognized (gdb) quit
burger$
Sad. It doesn't work because GDB doesn't know where the executable lives. So, let's try again, by invoking GDB directly on the executable:
burger$ gdb .libs/hell

(gdb) break main
Breakpoint 1 at 0x8048547: file main.c, line 29.
(gdb) run
Starting program: /home/src/libtool/demo/.libs/hell
/home/src/libtool/demo/.libs/hell: can't load library 'libhello.so.0' Program exited with code 020.
(gdb) quit
burger$
Argh. Now GDB complains because it cannot find the shared library thathellis linked against. So, we must use libtool in order to properly set the library path and run the debugger. Fortunately, we can forget all about the.libsdirectory, and just run it on the executable wrapper (see Execute mode):
burger$ libtool --mode=execute gdb hell

(gdb) break main

(gdb) run
Starting program: /home/src/libtool/demo/.libs/hell Breakpoint 1, main (argc=1, argv=0xbffffc40) at main.c:29
29 printf ("Welcome to GNU Hell!\n");
(gdb) quit
The program is running. Quit anyway (and kill it)? (y or n) y
burger$
