Is anyone able to build on Win 7

Hi Peter,

glad to see that other have the same problems:)

But seriously, on Windows 7 I'm currently experiencing the same
massive build problems and I'm not sure what the root cause of these
problems is.

I found the following bug which exactly describes the problems I'm facing:

Among others, these are:

- rm: cannot remove directory `META-INF': Directory not empty
- error:  cannot create example2.html: Permission denied
- [javac] C:\Software\OpenJDK\jdk8\langtools\src\share\classes\com\sun\tools\javac\util\
error: error while writing SharedNameTable:
(Access is denied)

but I also saw the 'out of memory' and 'for' problems mentioned by you.

The description of bug 6903517 references the "Big List of Dodgy Apps"
( This is a list
in the Cygwin FAQ which lists applications like Virus Scanners which
can interfere with Cygwin in an unpredictable way. An indeed the
Windows 7 box on which I observe the problems has some of them
installed (e.g. McAffe {Agent, GTI Proxy Agent, Intrusion Prevention,
VirusScan Enterprise, AntySpywaare Enterprise} to name just a few).

On the other hand, on the same Windows 7 box I have a virtual machine
running inside VirtualBox  with WindowsXP which has the same McAffe
software installed and it is running without any problems. The OpenJDK
build always succeeds in the virtual machine!

So I'm not quite sure of this is:
- a problem of some additional software which is running on my Windows
7 box and interferes with Cygwin
- a general Windows7 problem
- a problem of the specific Cygwin version I'm using
- a problem of Cygwin running on 64-bit Windows 7

I'll try to further narrow down the problem, but of course any hints
are highly welcome (unfortunately I can't easily get rid of the McAffe
stuff without losing my job, so please don't advise this:)


PS: below you can find the exact versions of the software/hardware I'm using:

64-bit Windows 7, SP 1
Dual Core Intel i7, 8GB RAM

Cygwin (output of uname -a):
CYGWIN_NT-6.1-WOW64 WDFN00299915A 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin
bash 4.1.10(4)  // installed by Cygwin setup.exe
make 3.82  // compiled by myself

In the Virtual box VM I have the following system:

64-bit Windows XP Professional Version 2003 SP 2

Cygwin (output of uname -a):
CYGWIN_NT-5.2-WOW64 WDFV00248216A 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin
bash 4.1.10(4)  // installed by Cygwin setup.exe
make 3.82  // compiled by myself
