Dependancies and New release ?

[n***@atelier-web.com]

Hi all,

I can see that there are a lot of commits on the cvs server :)
When should we exepect to have a new (stable) release of pcc ?

I have too an other question,
what are exactly the dependencies of pcc ?

Thanks for your answers,
Nick

PCC depends on the standard library, plus some functions
you should find in the libcs of most unix-like systems these
days. To compile it, you'll also need flex & yacc (or bison,
or something compatible) and perhaps make to make building
easy (no pun intended). Obviously you need something to compile
with.

It's hard to be more exact than that without listing every
function PCC calls. Inspecting the includes should give
you a good idea, though.

Thanks for your answer (and Szabolcs Nagy)
It's a good news, so pcc is really portable ^^

Cheers,
Nick

what are exactly the dependencies of pcc ?

to build it you need a posix environment with
sh, flex, bison, make, etc and a c compiler

to use it you need pcc-libs, an assembler, a
linker (eg. as and ld from gnu binutils) and
a libc provided by the system

..so nothing unreasonable

Difficult to say, but most likely this year.
