What is the use of EXTRA_DEPENDS?

[jetm]

Hi,

All the generated Go recipes have EXTRA_DEPENDS but the go-gen code has no other use:

meta-sca/scripts/go-gen

Line 399 in 3ba84c1

EXTRA_DEPENDS += "%rdepends%"

I introduced EXTRA_DEPENDS as variable that can be set manually.
Basically in a generated recipe DEPENDS is extracted automatically and enhanced by the manual settings from EXTRA_DEPENDS.

By this one can inject dependencies that can't be determined by the recipe generator. Plus in case of an update the settings of EXTRA_DEPENDS are taken over from the older recipe(s)

Does this answer your question?

For clarification to see if I understand, at the moment, EXTRA_DEPENDS only is treated as data that eventually could be reused to update generated recipes?

[priv-kweihmann]

Yes, exactly - It's meant as a way to preserve dependencies that have to be defined manually.
Classic example:

a recipe depends on some c library, which can't be seen by the recipe generator, so typically one would inject this dependency via EXTRA_DEPENDS += "some-lib"

With this it would be preserved with the next update of the generated recipe

Thank you!
