[yocto] adding package management

[Tim Coote]

Hullo
I'm new to yocto, so I'm probably not going about this in the optimum way.

I'm trying to add package management to a yocto build. My preference would be yum/rpm on a rh/centos/fedora distro (as that's the distro used elsewhere), but I don't think that's feasible.

I've added:
[code]
IMAGE_FEATURES += "package-management"
IMAGE_INSTALL_append += " apt perl"
[/code]

to the bottom of …conf/local.conf (I started without the perl, which I added to fix this specific issue). However, when I run
[code]
bitbake core-image-minimal
[/code]
I get the following error
[code]
[tim at mercury mybuilds]$ less /opt/poky/mybuilds/tmp/work/qemuarm-poky-linux-gnueabi/core-image-minimal-1.0-r0/temp/log.do_rootfs.18707

[/code]

the rpm for dpkg-1.16.8-r18.0.armv5te does indeed include that dependency. However, the file *is* present:
[code]
[tim at mercury mybuilds]$ ll /opt/poky/mybuilds/tmp/sysroots/i686-linux/usr/bin/perl-native/perl
-rwxr-xr-x 1 tim tim 244 Dec 10 11:04 /opt/poky/mybuilds/tmp/sysroots/i686-linux/usr/bin/perl-native/perl
[/code]

… and since it's a couple of days old, I can see that adding perl after apt to IMAGE_INSTALL_append is pointless.

Have I missed something obvious? Is this a real issue?

Should I add a package manager some other way in any case?

thanks
Tim
