Re: [Tinycc-devel] What is the exact Darwin port status? (i.e. macOS)

[Christian Jullien]

I start to better understand (fix me if I'm wrong).
* On Darwin I can only make a cross compiler, i.e. make for example a tcc
compiler that, when built, will run on Windows.
* On Darwin, 'make' alone is not supposed to produce something usable to any
purpose. IMHO, make should produce an error in this case.
* Btw, why are there some __APPLE__ in tccrun.c

Because "tcc -v" is not a tool to tell you which OS you're on.

Because your tcc is a compiler for Linux.  A Darwin -> Linux cross compiler
if you want to.

See 'make help' for how to configure cross compilers.
