First PKGBUILD: 'cannot stat' error for source file

HyperBaton · 2011-04-04 14:04:04

I'm attempting my first PKGBUILD and I've run into some trouble.

PKGBUILD:

# Maintainer: Simon Wydooghe <hyperbaton at gmail dot com>

pkgname=vpcs
pkgver=0.21a
pkgrel=1
pkgdesc="Simulates up to 9 computers for ping/traceroute purposes."
arch=('i686' 'x86_64')

makedepends=('p7zip')
source=('${pkgname}_${pkgver}.7z::http://downloads.sourceforge.net/project/${pkgname}/binary/${pkgver}/${pkgname}_${pkgver}.7z')
noextract=('${pkgname}_${pkgver}.7z')
md5sums=('dac71bdf9d04a3b7e69fe25b15f1ee5c')

package() {
  local vpcsdir="opt/vpcs"
  local binary="vpcs32"

  cd "${srcdir}"
  mv ${pkgname}_${pkgver}.7z.part ${pkgname}_${pkgver}.7z
  7z e -o"${pkgname}-${pkgver}" "${pkgname}_${pkgver}.7z"
  cd "${pkgname}-{$pkgver}"
  mv startup.vpc readme.txt ${pkgdir}/${vpcsdir}
  if [ $CARCH = "x86_64" ]; then
    binary="vpcs64"
  fi
  mv ${binary} ${pkgdir}/${vpcsdir}/vpcs
  chmod +x ${pkgdir}/${vpcsdir}/vpcs
}

Error when running makepkg:

[hb@hb-desktop vpcs]$ makepkg

    Aborting...

So it seems that '.part' is being added to the source filename when being downloaded by makepkg. I added '${pkgname}_${pkgver}.7z::' in front of the source url to rename the file (I believe that's correct, no?).

This is the PKGBUILD directory after running makepkg:

[hb@hb-desktop vpcs]$ ls -l
total 1152
-rw-r--r-- 1 hb hb     884 Apr  4 15:47 PKGBUILD
drwxr-xr-x 2 hb hb    4096 Apr  4 16:01 src
-rw-r--r-- 1 hb hb 1168714 Mar  8 04:18 vpcs_0.21a.7z.part

I can stat the file in question:

[hb@hb-desktop vpcs]$ stat vpcs_0.21a.7z.part 
  File: `vpcs_0.21a.7z.part'

So can someone tell me which moronic error I've made this time? :-)

source=('${pkgname}_${pkgver}.7z::http://downloads.sourceforge.net/project/${pkgname}/binary/${pkgver}/${pkgname}_${pkgver}.7z')
noextract=('${pkgname}_${pkgver}.7z')

don't use single quotes here, use double quotes. pkgname and pkgver are never expanded

source=("${pkgname}_${pkgver}.7z::http://downloads.sourceforge.net/project/${pkgname}/binary/${pkgver}/${pkgname}_${pkgver}.7z")
noextract=("${pkgname}_${pkgver}.7z")

Excellent, thanks, that did the trick!

While I've opened this topic anyway, I have another question. The application in question uses a configuration file which it only looks for in the directory the executable resides in (unless a specific command line argument is given). For this reason, it seems most logical to place the application under /opt. But /opt is not in $PATH by default. What is the best way to add the directory /opt/vpcs to $PATH but to also remove it from $PATH when the application is removed?

No need to change the path, add a shell script to start vcps to the package, place that in $pkgdir/usr/bin .

the shell script would look something like this :

#!/bin/bash
cd /opt/vcps
<insert startup command for vpcs>

Thanks for the reply, I did indeed try it like this yesterday and it worked like a charm. I should have updated my own topic though
