I'm half way through a painful move from win2k as
my primary OS at home, to linux, where I'll run win 95 and maybe 2K in a virtual
machine...
One of the points of the exercise is to be able to
build cygwin a little faster :]. To that end I'm building a
cross-toolchain.
I'm caught in the chicken-and-egg bit with newlib
and gcc, and would appreciate some pointers - either to reading material,
or to actions. (I recall Mumit's page being rather dated... thus my
question).
Steps so far:
grabbed the winsup tree, added bfd, binutils and
opcodes all from cvs.
Built bfd, opcodes and binutils, with
--target=i686-pc-cygwin. installed that (/usr/local).
grabbed gcc from a cygwin mirror. configured
with --target=i686-pc-cygwin.
That fails partway thrugh the build (see the errors
below). I figure thats because no cross-headers have been installed. So... I go
to build newlib, but cannot as, you guessed it, i686-pc-cygwin-gcc doesn't exist
yet.
Hints ?
