This article is from the MachTen & CodeBuilder FAQ, by Jaime Julca firstname.lastname@example.org with numerous contributions by others.
Because Professional MachTen supports virtual memory and protected memory,
it is the recommended version for software development. Power MachTen, on
the other hand, has some unique software development capabilities. Since
Power MachTen's compilers generate the same binary PEF formats as
Metrowerks, Symantec, and MPW, Power MachTen can develop pure Macintosh
applications, or even combine Macintosh and UNIX software development tools
to generate hybrid applications. Furthermore, Power MachTen is the only
version that includes a Fortran compiler.
C4. Will other Macs be able to run my applications without running CodeBuilder?
Of course. Distribution format is completely up to the developer.
CodeBuilder can create either Mac standalone or UNIX-based applications and
includes examples of both types.
C5. How much source code and documentation does CodeBuilder include?
About 400 MB of source code and 40 MB on online docs.
C6. Does MachTen support hard links?
In UNIX, linking allows several file names to be associated with the same
physical file. Power MachTen properly supports UNIX soft links and hard
links via link(2). Professional MachTen only supports soft links.
