Common mistakes in a recipe
From Openembedded.org
This page should list common (!) mistakes when defining a recipe. a link or one sentence explaining what the problem is are a bonus. But keep it short!
(R)DEPENDS, etc.
libiconv in (R)DEPENDS
- Use "virtual/libiconv" instead as glibc based systems already have libiconv functionality from glibc. Uclibc based systems will get it from "libiconv". By building libiconv in glibc build You risk a corrupted TMPDIR which will need to be restarted from scratch.
kernel modules in RDEPENDS
- Never use RDEPENDS to drag kernel modules into an image, use RRECOMMENDS instead. The reason is that some devices can have those modules built-in into kernel.
