I had a look on the sourceware for the new cygwin sources.  I found lots
of snapshots around 4MB in size.  I built my cygwin cross compiler
following Mumit Khan's howto.  It said to download the Cygwin dev
sources which are around 27MB in size.  I thought I needed an update of
this but there is only one on sourceware and it is quite old (the same
one that I have already got).  What is the difference between the dev
sources and the other snapshot soureces ?  Which ones do I need to build
an up to date cygwin package on a Linux host ?  I want to be able to
build the latest Insight code.  Are there any other pacages I need.  I
don't really want to build on a Win32 box, but would like to know if any
extra packages are required to do this (just incase I get real
desperate).

Thanks,
Brendan Simon.

Actually, the B20.1 sources should include the libtermcap directory.
Are you saying that it isn't there?

I'm not sure why you're not just downloading the prebuilt binaries
from Mumit's site.  It would save you a lot of time, it seems.

I believe Brendan is looking at supporting other targets, so needs to
build it locally.

Brendan, the easiest way to get the runtime support is find a machine
with Cygwin installed, and just grab the includes and libraries from
/Cygnus/cygwin-b20/H-i586-cygwin32/{include,lib} and you should be all
set.

If you want to build it locally without having to download the whole
bit, here's how (untested, but the basics are there ;-): download
the following "split" components from sourceware Cygwin site[1]:

  toplevel.tar.bz2
  config.tar.gz2
  etc.tar.gz
  include.tar.gz
  libiberty.tar.gz
  newlib.tar.gz
  winsup.tar.gz

[1] ftp://sourceware.cygnus.com/pub/cygwin/cygwin-latest/src-by-top-dir/

Now unpack all of this in some directory, say cygwin-b20 and build/install
using your cross-compiler. Of course, unless you already have cross
compiler going, there may be a chicken and egg problem -- to build the 
cross-compiler, you need the runtime; to build the runtime, you need to 
the cross-compiler. If you already have a cross-compiler, you should
already have the runtime, right?

Since you may need termcap, also download the libtermcap.tar.bz2, which
has some modifications to support "cygwin" terminal type.

Mumit

I have already built a linux hosted powerpc-eabi targeted cross-compiler.  I
have also built a cygwin hosted powerpc-eabi targeted cross-compiler (this
was built on a linux machine following Mumit's howto - thanks).  I previously
built the linux-cygwin cross-compiler using the dev-cygwin sources.  I assume
that I don't need the "src-by-top-dir" for this case.

This is the bit that I think I'm missing.  Apparently this is part of newer
cygwin releases/snapshots which is what I was trying to find, but I got
confused between the dev-cygwin sources and other cygwin sources.  OK, so I
will get the libtermcap.tar.bz2 package and see what happens.  BTW. Is this
package a cygwin only package or is it a generic package for all posix
compliant APIs ?

Thanks,
Brendan Simon.

It's BSD's termcap so yes.

It is the GNU termcap sources.

Sorry.  It's the BSD sources as someone else has mentioned.
