Building GCC 3.3 / MingW: The Saga Continues

[Mohan Embar]

Hi folks,

Thanks to Lars' build tips for building GCC 3.3 / MingW:

http://gcc.gnu.org/ml/java/2003-02/msg00134.html

I was able to build the cross compiler too. Rather than messing around
with the crossed native compiler, I first decided to see if I could
build a Win32 "Hello, world" program from Linux. This worked. Then
I modified, the libswt.a build shell script from:

http://gcc.gnu.org/ml/java/2002-12/msg00105.html

and built a Win32 libswt.a from Linux.

I then built the Hello.java SWT example from:

http://www-106.ibm.com/developerworks/library/j-nativegui/
(Listing 2)

and ran in on Windows. It crashed with:

Exception in thread "main" java.lang.UnknownError: Runtime.loadLibrary not
implemented
   at 0x005260bc (Unknown Source)
   at 0x00525bdc (Unknown Source)
(etc.)

I'll look into this later.

How impractical is this? Could someone educate me? Given the large
amount of code sharing made possible with MS's BSD-layer-wannabe 
implementation, although imperfect, wouldn't creating two parallel code sets
create a maintenance headache?

To my knowledge, a formal patch was never created for

Ranjit's suggestion:
http://gcc.gnu.org/ml/java/2002-12/msg00295.html

with Tom's naming convention factored in:
http://gcc.gnu.org/ml/java/2002-12/msg00320.html

Are we still okay with this approach? I wouldn't mind submitting
a patch for this if everyone was okay with it. (I'd have to read
up how to formally submit a patch, but I'm game for this.)

Thanks again for all your untiring efforts.
