[yocto] inc files in recipes

[Frans Meulenbroeks]

Dear all,

Peeking at flex I was wondering whether we should try to avoid using
.inc files in recipes especially if there is only one recipe.

flex has:
frans at frans-desktop:~/yocto/poky-laverne-4.0$ ls meta/recipes-devtools/flex
flex_2.5.35.bb	flex.inc

Here the inc file could be merged into the bb file.
This has the advantage of having only a single file, so it is slightly
easier if you want to read or maintain the recipe.

For recipes with multiple versions (e.g. tar) it might be useful to
have inc files. It is really a tradeoff between easy access/reading
and maintainability here.

(and I think for some packages (e.g. gcc) the inc file is actually very useful!)

Frans

PS: laverne seems to have 255 inc files:
