error: failed to prepare transaction (could not satisfy dependencies)

Hi,

I was going to install a winff package (a GUI front end to ffmpeg for converting between video formats), but when I ran yaourt -S winff and tried to install it refused because it isn't for the x86_64 architecture. So I decided to edit the PKGBUILD and perhaps try to force it anyway, but then I saw that the PKGBUILD is actually getting the precompiled RPM package and as I checked, while there was no precompiled 64bit version of the RPM there was one for a deb version that is offered on winff site.

Since deb's are just archives I ended up, after a few tries, with this PKGBUILD which uses ar and tar commands to get to the binaries inside of the amd64 deb:

# Contributor: yugrotavele <yugrotavele@gmail.com>
# Modified by libervisco for x86_64
pkgname=winff-amd64
pkgver=0.42
pkgrel=1
pkgdesc="GUI for ffmpeg"
url="http://www.winff.org"
license=('GPL')
depends=('ffmpeg gtk gdk-pixbuf')
makedepends=('')
source=('http://winff.googlecode.com/files/winff-0.42-amd64.deb')
arch=('x86_64')
md5sums=('1febf5fd19fa76bdc1da06d3e6c4d3b8')

build() {
  ar vx winff-0.42-amd64.deb
  tar xvzf data.tar.gz
  install -Dm755 $startdir/src/usr/bin/winff $startdir/pkg/usr/bin/winff
  install -Dm755 $startdir/src/usr/share/winff/presets.xml $startdir/pkg/usr/share/winff/presets.xml
  install -Dm755 $startdir/src/usr/share/winff/winff.png $startdir/pkg/usr/share/winff/winff.png
}

So what I basically do is run yaourt -S winff and when it asks whether I want to edit it, I edit it and replace the original PKGBUILD content with above.

It successfully runs the build() commands, finds and installs the dependencies, but when it's time to install the actual new winff package is throws up this:

loading package data...
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: winff: requires ffmpeg gtk gdk-pixbuf

I don't get it. It installed all the dependencies (and I even checked whether winff works in one of the earlier tries when I manually installed gdk-pixbuf when the binary asked for it). What does it want now?

Here is the whole process:

[daniel@memeport ~]$ yaourt -S winff

A nice GUI frontend for ffmpeg.

I tried doing it without changing the package name to winff-amd64, but same thing happens. What's going on?

there are missing quotes in the depends array:
depends=('ffmpeg' 'gtk' 'gdk-pixbuf')

Ahh man, and that's it! It works.

I'm just wondering now how can I contribute this PKGBUILD to AUR, but I can read that in the wiki too.

Thanks!
