Hi,
With the advent of Cygwin64 and probably a small overhaul of the build
system to accomodate MinGW-w64, I'm hoping it will be easier to build a
cygwin cross-compiler.
I would like to ultimately end up with AUR packages for Cygwin, just like I
provide for MinGW-w64, which would allow people developing on Arch to
cross-compile from Linux. This is possible, as Fedora has the CygwinX
thingie going on, and I used that to build toolchains.
The million dollar question is of course, how to do this (highly preferable
from source)? I understand the Cygwin runtime is C++, so bootstrapping
isn't as simple as it sounds?
What I would imagine is this:
1. build *-w64-mingw32 toolchains capable of C++ in /usr/*-w64-mingw32
2. build and install gcc C compiler for Cygwin using mingw-w64 headers?
3. build and install cygwin runtime with --host=*-w64-mingw32 in
/usr/*-pc-cygwin
4. build rest of GCC linking to the cygwin runtime?
I know this looks flaky, and yes it probably is wrong. What is the proper
build order for a full bootstrap on Linux? Additionally, if possible, I'd
like to keep only one set of MinGW-w64 headers/libs, to prevent size bloat
for no apparent reason.
Thanks a million!
Ruben
