[oe] Added header file to linux kernel - how to export

[Mats Kärrman]

@ Fabrice
OK, I hear what you're saying.
I've read about "packaged staging" and it seem to be "a good thing" (http://marcin.juszkiewicz.com.pl/2008/07/01/packaged-staging-and-what-it-gives/).
I did try using "oe_stage_append_mymachine()" but got an error saying something like "there is no oe_stage so you can't append, use oe_stage() instead". So I tried "oe_stage_mymachine()" but still got the same error... Then I tried "oe_stage()" that worked but I don't wan't to do it "unqualified". (I'm using OE "tested_2010-12-30", maybe this is fixed in later releases.)

@ Henning
Regarding not using "do_stage" I found this: "https://wiki.yoctoproject.org/wiki/Merging_packages_from_OpenEmbedded" and know that Yocto and OE are getting closer involved. Also I found posts about "kernel_do_stage()" from kernel.bbclass but I have no such function in my OE version.
This info "http://openembedded.org/index.php/Legacy_staging" suggests STAGING_INCDIR -> ${D}${includedir} but that doesn't make sense to me because I want the file where other recipes could reach it.
I have seen your comments on other posts also saying "don't use do_stage". Could you please point me off to somewhere where I could get the background and what would be "the right" way to do this?

Best regards,
Mats

Mats,

Installing myfile.h during do_install() certainly works for you right now.

But it won't if you plan to use packaged-staging in the future. Hence my advice to do this rather during do_stage()

With kind regards,
