Libraries

Libraries are a collection similar of Lightfoot object files (.lfo) files that are grouped together into one Lightfoot library file (.lfl). The linker searches library files for unresolved references while building an application.
The Lightfoot SDK comes with a large number of libraries in two forms, debug and non debug.

Debug libraries

The debug libraries provided with Lightfoot contain diagnostics that can be enabled at runtime to diagnose and solve problems. For those libraries with source code available, you can also debug the library routines.

Non debug libraries.

Non debug libraries contain no diagnostics and cannot be debugged. Your applications should always link against non debug libraries unless you suspect there are problems with the libraries.
