RTL and FCL are not built with debug information by default. See these links for more information:

Hi

1) make directory in a tmp location of your choice eg: /home/user/tmp/__fppdf
2) copy the file "fppdf.pp" to your tmp-location
3) rename "fppdf.pp" in your tmp-location to "__fppdf.pp", remember the unit name inside the file 
4) in your app change the uses to use "__fppdf" and include your tmp-location in "Project-Options-Path"
5) recompile your project with debug-info on.
6) now you should be able to step into the fppdf.pp source...
7) when you're done, simply change your uses clause back to "fppdf" and remove tmp-location from project options.
Give that a whirl and see what happens
