other place except core-image-base.bb to enable tools

stevenyu — Wed, 22 Jan 2020 03:29:51 GMT

Hi Expert,

Because we don't include many tools/packages in core-image-base.bb, but the rootfs is quite large.

As I know, we need to add module name to this file to enable specific function, e.g. dhcp, but I have still seen lots of tools be enabled by default. Would you please advise where these tools are enabled ?

FILE: sources/poky/meta/recipes-core/images/core-image-base.bb

SUMMARY = "A console-only image that fully supports the target device \
hardware."

#IMAGE_FEATURES += "splash"

LICENSE = "MIT"

inherit core-image

IMAGE_INSTALL += "dhcp"

Regards,

Steven Yu

Hi stevenyu ,

For default enabled tools you can refer .bbclass file of core-image (FILE: sources/poky/meta/classes/core-image.bbclass). As core-image class is inherited from core-image-base.bb.

Hi steven,

You only need to configure build/conf/local.conf, like below:

(1) adding packages

# for example, add perl

... ...

IMAGE_INSTALL_append = " \
perl \
perl-module-base \
perl-module-findbin"

......

(2) deleting packages

......

PACKAGE_EXCLUDE = "package_name1 package_name2 package_name3 ..."

......

In addition, on how to add / delete packages in Yocto, you can find many documents from internet.

Have a nice day!
