Cross Compiler running under Win32

Cross Compiler running under Win32

[Steven Scholz]

Hi there,

does someone know of a cross compiler (producing code for let's say MPC8xx) that
is running natively under win32 (Windows2000/XP) without stuff like CYGWIN?

I'am just wondering.
Apparently MVISTA released their new "DevRocket" which is supposed to run under
WindowsXP. So I assume they have cross compilers for "30 processors from 8
architectures" running under Windows...

Thanks.

Green Hills Software has its own compiler which we can host from Windows,
Linux, Solaris and HPUX. At the moment we still make use of the GNU linker
though, so to use our stuff you still need binutils working on your host.
Apparently the compiler group is considering supporting Linux targets with
our linker, I have no idea what the status of that is though.

Any particular reason why you don't want to use Cygwin?

PS. I don't know if this list allows plugging non-GNU software, if it
doesn't please ignore this bit. Our compiler produces significantly
smaller and faster code that pretty much anyone else. An internal test
showed code size differences when compiling the Linux kernel at 20+%
smaller than GNU gcc 3.x and well over 30% against 2.95. We didn't do much
benchmarking, but the speed difference was apparently big enough that it
was visable during kernel boot. I believe the kernel cross compile was
entirely with our tools.

But the trouble with analogies is that analogies are like goldfish:
sometimes they have nothing to do with the topic at hand.

They could well be using cygwin for the compilers; they charge
enough that the licensing fee for cygwin is peanuts, I bet.

But what's wrong with using Cygwin?

Answering my own question, it's a bit of a challenge to use
cygwin in an installed package because there are fairly
frequent incompatibilities introduced in the cgywin dll,
so if the user installs a newer or older version than you
expect, your installed package won't work.  It's rather
maddening.  And it seems there's no way to 'embed' cygwin
in such a way that it uses a private copy of the cygwin dll.

I think Cygwin is much too much overhead for just compiling a small application.
I was told that I could take just the GCC package from Cygwin without installing
all of it.

"licensing fee for cygwin" ???
So it's not free?
Could we just take the GCC package and the DLL and distribute it together with
our software and install it on our costumers Windows PCs?
We have to be able to generate and (cross-)compile code on our costumers PCs
that is than transfered to our devices and executed.

It is free, if you obey the GPL, and distribute source code.
Otherwise, you can get a commercial license.

Yes.  However, this is complicated by the fact that if the
user already has cygwin installed, its cygwin DLL may conflict
with yours.   It's not a trivial problem to address.
If you're willing to keep your package up to date with
the latest Cygwin all the time, it's probably managable;
in case of conflict, the user can update both Cygwin
and your tools and get things working again.

We actually did some of that at Ixia, and I have the scars to prove it :-)

FWIW, this is the mvista marketing spiel:
