The attached is a second recipe; this one builds a linux->cygwin
gcc-4.5.0 compiler with sysroot support, as well as enabling libgomp.
It differs from the "native" cygwin 4.5.0 compiler in the following ways
(other than the obvious, of course):
graphite is not enabled
lto is not enabled
To use this recipe, I recommend (a) modifying the various settings at
the top as needed (b) cut and paste small sections (10 lines or so) into
a terminal -- rather than attempting the "run" the recipe as a script.
It's not that polished.
Using the cross-compiler generated using this recipe, the "sysroot"
support in libtool-2.2.11a passes its own tests (the cross-compiler
built using the previous recipe, because it had no sysroot support,
caused those tests to be skipped).
I was able to rebuild cygwin itself using this compiler with no issues
(except those related to -Werror; there are a number of files in cygwin
that cause alias warnings).

Based on Corinna's posted procedure
http://cygwin.com/ml/cygwin-developers/2010-08/msg00099.html
with a few changes, I was able to create a working linux->cygwin toolchain.
The changes I had to make were:
1) I had to do the "unpack a couple of cygwin distro packages" step and
the "postinstall" step BEFORE trying to compile gcc. Otherwise,
compiling libgcc fails because of "missing stdio.h".
2) I *did* have to patch gcc's libstdc++-v3/crossconfig.m4 file.
Otherwise, I got a complaint about unsupported "host/target" combination.
3) And, since Dave's patches do modify m4, Makefile.am, and configure.ac
files, I did run automake and autoconf manually in the affected
subdirectories, before attempting to build.
Testing:
Hello World in C, worked fine
Hello World in C++, worked fine
Rebuilt cygwin-1.7.6 from source, and installed into win32 -- worked fine.
Now, how this build -- unlike my previous attempt -- doesn't have a
sysroot. The $target libs are installed directly under
$host_prefix/$target_triple. Also, unlike the native cygwin 4.5.0
compiler, this one doesn't --enable-libgomp nor --enable-graphite nor
--enable-lto. And builds only C, C++, and Fortran.
But...this one works. I'll try again, with some of the other options
and maybe sysroot support, but not until next week.
I've attached my *working* recipe, based on Corinna's instructions. It
also includes the recipe for then building cygwin itself, and packaging
the results for installation on win32.

This is much like the MinGW cross toolchain build scripts. The scripts seem not to be able complete the build procdure of gcc.

linux->cygwin cross build environment
Last weekend I attempted to setup a linux->cygwin cross compiler (and
basic sysroot). However, it didn't work: while a simple C 'Hello World'
app could be compiled, copied over to a win32 system and executed, a C++
'Hello World' did not:
1) using the cygwin-provided cygstdc++-6.dll and cyggcc_s-1.dll, it
segfaulted.
2) copying over to the win32 system ALSO the cygstdc++-6.dll and
cyggcc_s-1.dll built as part of the cross toolchain, and running the C++
hello world app -- it didn't segfault. But it didn't print anything to
stdout (std::cout), either.
Now, I've build linux-hosted cross compilers before -- and I'm very
familiar with cygwin, too -- so I'm not exactly a novice here. But...I
wonder if I'm just doing something silly, and need another pair (or
hundred) of eyes to point out the obvious.
so, I've attached my build procedure (WARNING, for the archvies: the
compiler produced using this procedure is BROKEN. DO NOT USE).
I based my compiler on Dave's recent 4.5.0-1 release, and the current
cygwin binutils packages.
Anybody have a suggestion? What am I doing wrong?
