The description for native recipes in STAGING_DIR_HOST might also trick people into thinking that native recipes are installed into host directories like /usr. Here's a suggested note to add to the native bullet point in the STAGING_DIR_HOST glossary entry: Note { This does not mean that -native recipes are installed into host paths like /usr. Rather, they are installed into [STAGING_DIR_NATIVE]. When compiling -native recipes, standard build environment variables like [CPPFLAGS] and [CFLAGS] are set up so that both host paths and [STAGING_DIR_NATIVE] are searched for libraries and headers (using, for example, GCC's -isystem flag). This emphasises that the STAGING_DIR* variables should be viewed as an input variables by tasks such as [do_configure], [do_compile], and [do_install]. Having the real system root correspond to STAGING_DIR_HOST makes conceptual sense for -native recipes, as they make use of host headers and libraries. } Cheers, Ulf 66714 1 ulfalizer 2016-09-29 14:41:01 +0000 I also just spotted an error in the STAGING_DIR_HOST glossary entry (that might be my fault). This is not correct for -native recipes: This sysroot is the one that the recipe's do_populate_sysroot task copies files into. Instead, it could say this: For most recipes, this sysroot is the one that the recipe's [do_populate_sysroot] task copies files into. Exceptions include -native recipes, where do_populate_sysroot instead uses [STAGING_DIR_NATIVE].

Thanks, Scott 66812 4 ulfalizer 2016-10-03 16:22:34 +0000 Looks good to me. Maybe it would make more sense to have the note after the second (native) bullet point, but I'm okay with the current version if that's awkward to do or if you think that it spaces things out too much. Thanks, Ulf 66833 5 srifenbark 2016-10-03 19:27:25 +0000 Ulf, I wondered about the ultimate placement of that note. It did not seem to fit at the bottom too well. I will move it as suggested. See http://www.yoctoproject.org/docs/2.2/ref-manual/ref-manual.html#var-STAGING_DIR_HOST. Since you were okay either way... I am setting to RESOLVED and putting the doc flag to "done." Thanks, Scott
