PREFIX on Cygwin

Hello All,

I was trying to get PREFIX portage to work on Cygwin on
Windows (XP). I 
am facing some issues in the process. Has anyone tried this
before with 
Prefix Portage? I found that there is a project specifically
for this 
purpose at http://gentoocygw
in.sourceforge.net but that does not seem to 
support Prefix version of portage.

Any pointers in this regard would be appreciated.

Specifically today, I am facing a problem while emerging
anything. I get 
an error saying that I am trying to emerge a package with a
syntax error 
or corrupt ebuild file (which is definitely not the case).
Also, emerge 
refuses to proceed with any dependency analysis whatsoever.

Thanks,
Nimish

Hi!

Interesting to see some works along the windows way.  We
never tried
anything alike, but of course we would be very happy if it
would work
somehow in the end.

Could you give any error messages you get?  Maybe they look
familiar or
does somebody here know what they mean exactly.

Regards

Thanks for offering help. Here are some of my problems:

1. First of all under cygwin, any path that has two slashes
at the 
beginning is treated as a network path. So the seemingly
harmless "root 
+ portage_consts.EPREFIX" thingy fails with error
message "No such 
hostname or network path: //opt/cyg-prefix". I worked
around that by 
changing root from "/" to
"/cygdrive/c/cygwin_root".

2. Secondly, emerge is not able to generate dependency cache
for the 
system. I have two overlays in my tree and all I can see
under 
var/cache/edb is those two empty directories (plus the
normal base 
portage one). When I run emerge with --debug and --regen
options, I get 
this error for each ebuild file in the tree:
aug_get(): (0) Error in
sys-devel/gcc-config-1.3.12-r4.ebuild (1)
                Check for syntax error or corruption in the
ebuild

3. Same error is raised when I try to run
"ebuild" command on any of the 
ebuilds with any option. At present, I am trying to trace
through the 
ebuild/emerge code to see what is going wrong. I have a
feeling that 
somewhere the root is getting set back to "/" or
something like that.

If any of these error messages mean anything to you, please
throw some 
light.

Thanks,

I think that workaround is reasonable.  However double
slashes should
have been tackled already sometime... ?  Anyone know
anything about
that?

What trees do you use?  I'm not entirely sure, but I think
this error
can mean that you don't have EAPI="prefix" in
your ebuild.  But I may
be very well mistaken.  I've seen the error myself before,
that's for
sure.

The ebuild tree is one I have been building on Linux for
quiet some time 
now. And it does have EAPI set to prefix for all ebuilds (at
lease the 
ones that are supposed to build).

Hi,

I'm wondering that cygwin has fixed the
hyperthreading-related bug[1],
only occurring on Windows >= XP, not until Win2000.
Well, there are some more recent posts on the list with some
patches to
the cygwin-dll, but did not really find it fixed.

Well, facing this problem, and some others which seems that
M$
implements things to prevent cygwin working on newer
Windows-versions,
we have switched to Interix now - planning to use portage on
Interix,
with wgcc[2] as 'cross-compiler' to produce native win32
executables.

Okay, I have Portage working reasonably well on Cygwin now.
The changes 
I made mostly involve fixing places where root has been
hard-coded to 
"/". There are a couple of other fixes also. I
would like to submit the 
patch.

Where can I find a current version of Portage so that I can
create a 
patch against it? Also, has the location for hosting the
prefix tree 
already decided?

Thanks,
- Nimish

Please do.  Can it be posted to this list (reasonable size?)

The repo location is still an issue.  I've been thinking
about a git
writable mirror or something that is back propagated to the
Gentoo SVN
repo.  Kind of ugly all.
I don't know exactly where to get the latest sources for
portage.  I
hope someone else on this list can answer this (exg?).

The latest snapshot is

http://dev.gentoo.org/~kito/distfiles/portage
-prefix-2.1.14.tar.bz2

Even if it is a bit old, I should have no problem in porting
the changes
to svn.

Thank you for the snapshot link.

I am attaching the cygwin patch here. Please let me know if
there are 
any comments or questions about any specific fixes.

Some notes:
  1. I have disabled the install_qa_checks on Cygwin for
now, since that 
takes forever to complete even for very small packages.
  2. Also, the unlocking for tuples almost invariably fails
on Windows. 
However, that does not create any trouble in most cases. I
have changed 
the code so that such failures are silently ignored.
Otherwise, it is 
very annoying to see the builds failing for no apparent
reason.
  3. Move cannot be performed on windows if the target file
exists. I 
have ignored such rename attempts.

Thanks,
- Nimish
