MOAI - my first package

Hello everyone,

I've written a PKGBUILD for MOAI (http://getmoai.com/) but I'm not sure about a couple of things.

- I've seen in several other git-based packages that pkgver is a date (I suppose it's the packaging date). Is this a good practice?
- I'm not sure about which dependencies are really needed. I used ldd and pkgfile to discover the shared libraries which were needed but I didn't include all of them.
The full list (minus proprietary driver) is here: http://pastebin.com/4YZ7MjG2. Is there a better way?

This is the PKGBUILD (which is working fine here):

# Maintainer: Federico Rampazzo < myemail at gmail >

pkgname=moai-git
pkgver=20130208
pkgrel=1
pkgdesc=''
arch=('any')
url='https://github.com/moai/moai-dev'
license=('custom:CPAL')
depends=('freeglut' 'glu' 'libgl' 'libxmu' 'libxi' 'zlib')
makedepends=('git' 'cmake')

_gitroot='git://github.com/moai/moai-dev.git'
_gitname='moai-dev'

build() {
  msg 'Connecting to GIT server...'

  if [[ -d ${_gitname} ]]
  then
    cd ${_gitname}
    git pull
  else
    git clone ${_gitroot}
    cd ${_gitname}
  fi
  git checkout linux
  msg 'GIT checkout done or server timeout'
  
  cd cmake/
  cmake .
  make moai
}

package() {
  cd ${_gitname}
  
  install -d ${pkgdir}/usr/bin
  install cmake/moai/moai \
    ${pkgdir}/usr/bin

} 

Thanks in advance

Re: MOAI - my first package

If you want to test your package for mistakes or missing / not required dependencies, take a look at namcap (pacman -S namcap). Simply run "namcap foo.tar.xz" will show you the output.

For creating a new package, it's best to use the prototypes which are included in the package abs (pacman -S abs). Then look them up in /usr/share/pacman.

Your package looks ok so far, but include a pkgdesc! And in your package() function you can do this with a oneliner

package() {
  install -Dm755 "$srcdir/$_gitname/cmake/moai/moai" "$pkgdir/usr/bin/moai"
} 

edit: namcap will show you, that you have to include the license, since it's not a license which is in the license package.

Re: MOAI - my first package

For GIT packages, the pkgver is automatically updated by makepkg right now - and it uses the date. Pacman/makepkg 4.1 will change that, but it's still a month or more away. If you make the package tomorrow, you'll see that the pkgver automatically changes to tomorrow's date.

For the deps, I would tend to error on the side of caution and include too many, especially since there's nothing unusual in that list. You only need to include the "top level" deps; looking at it, freeglut satisfies the majority of the packages in the list.

A couple of other notes, is this really an arch=('any') package? That's for packages that are completely architecture independent like scripts or data. If this compiles to a executable binary, you need arch=('i686' 'x86_64)

The install commands should include permissions at least. Both of your install statements could be written as one, "install -Dm755 cmake/moai/moai "$pkgdir/usr/bin/moai"

The rest has some real problems, especially with the "cd" commands. Please install the abs package if you don't have it installed already and refer to /usr/share/pacman/PKGBUILD-git.proto. If you have any specific questions about it, ask.

Re: MOAI - my first package

Thank you for your suggestions!

- namcap helped me with the unused dependencies and it turned out that freeglut was the only needed dependency
- I've fixed the arch, the pkgdesc and I've added the license
- I've replaced my build function with the one from PKGBUILD-git.proto (I just removed the double-clone and added the appropriate build steps)

Thanks again, I hope this is the final version

Re: MOAI - my first package

It's been mentioned previously, but I still suggest following the abs prototypes.

For example, this lets you build without dirtying your git source.

  rm -rf "$srcdir/$_gitname-build"
  git clone "$srcdir/$_gitname" "$srcdir/$_gitname-build"
  cd "$srcdir/$_gitname-build"

Also, 'x86' won't be recognized as an arch string. Use what Scimmia wrote.

dots (or just the awesomewm config)

$ whatis this?
this?: nothing appropriate.

Re: MOAI - my first package

The pkgver function is redundant right now, makepkg does that for you and doesn't recognize the function anyway. In 4.1, there's a better way than using the date anyway. See Allan's blog for details.

The second clone is making a copy of the original clone that you build in the copy, not in the original. Gives you a clean build dir every time you rebuild the package.

I don't see where you cd into the build dir at all, you cd cmake directly from $srcdir. That isn't going to work.

Re: MOAI - my first package

just about there, arch should be i686, not i386

Grammatical issue on pkgdesc, "A Open Source ..." should be "An Open Source..."
