Compile your program with lcc -G To start your program, type
a.out --pause-- argsIt will print out a message like
=> DEBUG NUB <= to debug: /usr/local/bin/ldb target a.out connect dynastar 1143In a separate window, execute the ldb command. You can also start ldb by typing just `ldb' or `ldb a.out'. You must execute ldb from the directory in which a.out was linked. ldb has a cd command so you can change directories without restarting. Type '?' to ldb for a list of commands.
If you just want to debug a running program, send it a QUIT, which the debug nub will catch.
