Making a kernel PKGBUILD

Hello,

I tried to make my own kernel package with the abs system. I studied the wiki documentation (http://wiki.archlinux.org/index.php/Cus … n_with_ABS)

After making all configurations in the PKGBUILD, I copied the "kernel126.install", kernel-config-file and the patches in /var/abs/local/kernel26-sn-client-04"

My PKGBUILD:

# Contributor: Flasher <Flasher@bayern-mail.de>
pkgname=kernel26-sn-client-04
pkgver=2.6.13
pkgrel=1
pkgdesc="The Linux Kernel 2.6.13.4 for sn-client-04 withpatches for softcam"
url="http://www.kernel.org"
depends=('module-init-tools')
install=kernel26.install

##### add any patch sources to this section
source=(config ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-$pkgver.tar.bz2 
    dvb_demux.c.patch av7110_ca.c.patch )

# Function to grab var from src
getvar() {
  old=$(cat Makefile | grep "^$1")
  echo $(echo ${old/"$1 ="/} | sed -e "s/[ ]*(.*)[ ]*/1/g")
  return 0
}

build() {
  cd $startdir/src/linux-$pkgver

  ##### Uncomment and apply any patches here
  patch -Np1 -i ../dvb_demux.c.patch || return 1
  patch -Np1 -i ../av7110_ca.c.patch || return 1

  # get rid of the 'i' in i686
  carch=`echo $CARCH | sed 's|i||'`
  cat ../config | sed "s|#CARCH#|$carch|g" >./.config

  cd $startdir
  sed -i "1,11 s|pkgname=$old_pkgname|pkgname=$pkgname|" ./PKGBUILD

When I execute the command "makepkg" I get the following error message:

[root@sn-client-04 kernel26-sn-client-04]# makepkg
: command not found
: command not found:
'/PKGBUILD: line 15: syntax error near unexpected token `{
'/PKGBUILD: line 15: `getvar() {
) does not exist.l scriptlet (kernel26.install

Does anybody know the mistake in my configuration?

Thanks for your answers!

Re: Making a kernel PKGBUILD

source=(config ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-$pkgver.tar.bz2 
   dvb_demux.c.patch av7110_ca.c.patch ) 

There should be no space after the "" and (although it might not matter) move your "dvb_" line all the way over to the left.
I'm guessing you do have that space after the "" which disregards the next line below as a continuation of the array. If thats the case, bash doesn't see an ending ")" to the array, hence your errors.

Re: Making a kernel PKGBUILD

Sorry, but this wasn't the mistake  :?

Now, all sources are located in one line:

# Contributor: Flasher <xxxxxxxxxxxxxxxxxxxx>
pkgname=kernel26-sn-client-04
pkgver=2.6.13.4
pkgrel=1
pkgdesc="The Linux Kernel 2.6.13.4 for sn-client-04 with patches for softcam"
url="http://www.kernel.org"
depends=('module-init-tools')
install=kernel26.install

##### add any patch sources to this section
source=(config ftp://ftp.kernel.org/pub/linux/kernel/v … er.tar.bz2 dvb_demux.c.patch av7110_ca.c.patch)

# Function to grab var from src
getvar() {
  old=$(cat Makefile | grep "^$1")
  echo $(echo ${old/"$1 ="/} | sed -e "s/[ ]*(.*)[ ]*/1/g")

}

build() {
  cd $startdir/src/linux-$pkgver

  #yes "" | make config

  make menuconfig

.....................

The error message is the same: (only line 14 instead of line 15)

[root@sn-client-04 kernel26-sn-client-04]# makepkg
: command not found
: command not found:
'/PKGBUILD: line 14: syntax error near unexpected token `{
'/PKGBUILD: line 14: `getvar() {
) does not exist.l scriptlet (kernel26.install

I think it must be correct  Any ideas?

Re: Making a kernel PKGBUILD

Problem solved 

I edited the PKGBUILD in Windows and copied it to the linux system.
After making a new PKGBUILD only in Linux with VI there were no errors.

But the two files look completely same  :shock:

Re: Making a kernel PKGBUILD

I got caught by that too, back in my early Linux days. It's to do with the unseen Line Feed/Carriage Return characters used in M$ - Linux/Unix/etc only uses Line Feed.

I believe there are Linux-compatible editors available for Windows, if you ever have to do this again.
