With its previous programming systems (MacPascal, the original LightspeedC, and Lightspeed Pascal), Think Technologies (now a part of Symantec) has built a reputation for delivering capable, reasonably priced, and easy-to-use development environments. LightspeedC 3.0 maintains that reputation by adding a source-level debugger to version 2.15 — further enhancing one of the most easy-to-use software-development environments available on the Macintosh.
The LightspeedC environment is completely integrated — there are no separate editor, compiler, or linker applications. As with previous versions, the project document forms the foundation of LightspeedC 3.0, maintaining all the information needed for the development environment to intelligently compile applications. This includes the interdependencies of the source files, the object code of the compiled sources, and optionally, the source-level debugger’s tables.
Having all the vitals in one place for a program under development allows LightspeedC to compile, link, and launch the program with a single command. It also provides for an automatic make capability — LightspeedC only recompiles those files that have changed since the last compile.
