[solved] more than one wine with patches

[GenProm]

Hi

Im new to gentoo. In fact i did not even install it yet. But i read the manual 2 times now and im aware that i have to fix the stage3 tarball for sucessful install. But i digress.

I'm a heavy wine user. This means i have different wine installations with different patches. Now im using ubuntu and my layout looks something like this:

wine-XX.tar.bz2 + Some Patch -> compile -> checkinstall -> wineX-with-PatchX.deb
wine-XY.tar.bz2 + Some Patch2 -> compile -> checkinstall -> wineY-with-Patch2.deb

So if i need/want to start a game/programm who needs a specific patch i just install the binary beforehand.

As far as im aware in gentoo i can emerge a wine version who is in the repos.

Question 1: is it possible to patch this version with a custom patch before the emerge compile ?

If so, can i emerge a different wine version and patch it with another patch. How do i switch between versions ?

Question 2: Is there something like checkinstall ? I think, this would be the easiest Option, just build my binaries like before and emerge the needed one onto my system.

I think you get my idea what i need to do. Please be so kind and explain a gentoo way of doing so.

GenProm,

Welcome to Gentoo. Applying a custom patch set is straightforward in Gentoo but requires some domain knowledge. The instructions on how to build the package—including what patches to apply—are contained withing the package's ebuild file. There's one ebuild file per supported version of the package. What you will do to apply a custom set of patches to a package is to copy the particular version of the package's ebuild to your local overlay and modify the ebuild to apply your custom patches. There's a place in the local overlay to store the patches as well (the ./files directory). After that, when you build the package, the patches will be applied. Google Gentoo Local Overlay for more details. Additional background information is in the latter part of the Gentoo Handbook. See Part 3. Working with Portage.

The second part of your question is addressed by Gentoo Portage's ability to build binary packages. Once the package has been built from source with the patches you want, you can make a binary package from the installed package with the quickpkg utility. For instance,

Thanks for the quick, precise and really helpful answer.

This is exactly what i want.
But some new questions have risen up in my bain...

- With you explanation i can see how i can make:

gentoo-rep-version-wine + Patch2 or Patch1 and get 2 binaries to use them easily

Also to clarify: i have to change the local overly file to the new patch i guess...

- What is when i need a version of wine who is not in the gentoo repo. Can i use the normal wine source from winehq.org and somehow tell emerge to use this folder like ~/wine-version-not-in-gentoo as a source for emerge and aplay my patches to them ?

GenProm,

Welcome to Gentoo.

First the good news, stage tarballs built since early July are fixed. Feel free to check. File a bug if you are still finding issues.

You're gonna need more domain knowledge. (Like the line from Jaws: We're gonna need a bigger boat!)

It's usually (not always, but usually) a fairly simple matter to create an ebuild for a new version of a package. In fact, it's sometimes as easy as copying the ebuild file. However, note that Gentoo's Portage tree always has lots of versions of wine in it. Right now, we have

Thanks for now i think i will figure the rest with some time and more reading. if not i will reopen. As far a support goes im really impressed with the gentoo-community

I hope install will go fine, tried it once till now and i got some grub erros. I will do a hardware upgrade anyway before my next try.

In this particular case, and since wine ebuilds supports the epatch_user function from eutils.eclass you can also easily use this functionality.
Suppose you want to compile wine 1.3.25 with foo.patch, and wine 1.3.26 with bar.patch, you will do the following :

1. Create directories :
   

   Code:

   # mkdir -p /etc/portage/patches/app-emulation/{wine-1.3.25,wine-1.3.26}

   
   
2. Move patchs you want to apply where you want :
   

   Code:

   # mv foo.patch /etc/portage/patches/app-emulation/wine-1.3.25/ # mv bar.patch /etc/portage/patches/app-emulation/wine-1.3.26/

   
   
3. You will have :
   

   Quote:

   $ ls /etc/portage/patches/app-emulation/wine-1.3.2* /etc/portage/patches/app-emulation/wine-1.3.25: foo.patch /etc/portage/patches/app-emulation/wine-1.3.26: bar.patch

   
   
4. And when emerging each version, you will have :
   

   Code:

   # emerge =wine-1.3.25 ... Applying user patches from /etc/portage/patches//app-emulation/wine-1.3.25 ...  *   foo.patch ...              [ ok ]

   
   
   

   Code:

   # emerge =wine-1.3.26 ... Applying user patches from /etc/portage/patches//app-emulation/wine-1.3.26 ...  *   bar.patch ...              [ ok ]

quick question about wine-9999: if I try to emerge it, I get a "missing keyword" error, but the ebuild has the following:
