Extending meta-toolchain-sdk

Extending meta-toolchain-sdk

[Mike Detwiler]

Hello,

I have run 'bitbake meta-toolchain-sdk' and installed the tarball that
it generates. However, I found that the sdk did not contain all the
third-party libraries that I would like it to have. For example, the
application I'm developing has a dependency on libgmp. I notice that
there are bitbake files for gmp in meta/recipes-support/gmp. Is there
a simple way (e.g. in build/conf/local.conf) to have this added to the
list of libraries that are included in the sdk?

Best regards,

-Mike

Mike, Dexuan:

A better way to do this is to define SDK-EXTRAs in the local.conf file:

SDK-EXTRAS += "libgmp"

That should do the trick.

Sau!

Dexuan, the patch did work. Thanks!

Saul, adding this line to my local.conf produced an error saying
nothing provides libgmp.

I tried the following line instead:

SDK-EXTRAS += "gmp-dev"

This did not produce an error, but it also did not seem to add the
library to the sdk. Is it possible that this is because the variable
SDK-EXTRAS is also set in meta/recipes-gnome/tasks/task-sdk-gmae.inc
with the line below.

SDK-EXTRAS = ""

It looks like this could clobber my setting of the variable, depending
on the order of evaluation.

I agree that your suggestion is a more desirable approach than
modifying the poky sources directly. I would also be willing to use
the layers approach suggested in section 3.4 of the poky handbook, but
I'm still trying to learn how to make that work. Any tips or
suggestions would be much appreciated.

Thanks,

-Mike

I think we can change the line of task-sdk-gmae.inc to
SDK-EXTRAS ?= ""
This allows the setting of environment variable to be used if a user does set it.
And I think increasing the PR of the related recipe files is also necessary, or else, the change may not actually take effect, unless we build from scratch or do a "bitbake -c clean xxx".
