This sounds very interesting. I have no experience with MinGW/MSYS, but
will most definitely start looking into it asap and see how hard it
would be to get the new build compatible with it.

Volker,
Thank you for amazing work!
Just a curious:
1. Do you have any performance numbers for hotspot built with MinGW? Is
it as fast as one built with MS VC?
2. Did you see any issues with third-party JNI code?
Thank you!

Hi Dimitry,
I I haven't build the HotSpot with MinGW - that would be a completely
different project.
I've just used the MinGW/MSYS environment (i.e. shell, make, various
Unix-tools) to
build the OpenJDK. The build still uses MSVC as compiler.
Building the HotSpot with the GCC from MinGW should

So I did more test..
- I wanted to compare with MKS and the first thing I hit on was a bug
in MKS's 9.4
An interesting tidbit...
I was talking to the JavaFX RE team which does builds on Windows XP and Windows
2003 X64.
They have always used CYGWIN for builds, but there isn't many Makefiles used on
Windows, it's
mostly Ant scripts. So CYGWIN is used but probably not a major player. No MKS

The stat theory is very interesting, but it is unclear to me if it explains all
of the problem.

Fantastic information set. Many thanks for all this digging.
I suspect, that our build infrastructure work may help, in that if we get rid
of the nested makes,
then I can only assume we will be doing fewer stat() calls, but I think we
still have a problem.
A year or so ago, I managed to

I have read http://cygwin.com/faq-nochunks.html#faq.using.bloda so
in the makefiles that just set the wrong
mx flags for your particular system.
Hope that helps some!
