Hi Alexander,
Based on your and Oliver Westermann's help, I came up with something that works
for our project requirements:
My application bitbake file looks like this:
EXTERNALSRC =
"${@os.path.abspath(os.path.join(os.path.dirname(d.getVar('FILE')), '..', '..',
'src'))}"
inherit externalsrc
S = "${EXTERNALSRC}"
inherit cmake
externalsrc.bb expects EXTERNALSRC to contain an absolute path. We have a
relocatable workspace based on a git tree with submodules, so I calculate the
absolute path of the source based on the bb file location. Our src directory is
a cmake project, so I only have to convince cmake to use the EXTERNALSRC
location for an out-of-tree build in WORKDIR by setting S.
The workflow for our project developers then becomes:
bitbake -c cleansstate <application-name> && bitbake ...
I can hide this in a wrapper Makefile.
Am I missing anything?
Regards,
Pieter Smith
