Hi all,



I am trying to add Hello world package, my path is as follows,

*/home/siguser/yocto/poky*


    --meta-bebot
       --recipes-bebot
         --helloworld
           --helloworld.bb


                +-------------------------------------------


                |   +-------------------------------------------

                DESCRIPTION = "Simple helloworld application"
                SECTION = "examples"
                LICENSE = "MIT"
                PR = "r0"
                SRC_URI = "file://*hello.c*"
                S = "*/home/siguser/workspace/bebot-apps/helloworld*"

                do_compile() {
         	${CC} hello.c -o helloworld
                }

                do_install() {
	        install -d ${D}${bindir}
	        install -m 0755 helloworld ${D}${bindir}
                }
          +-------------------------------------------


                +-------------------------------------------
 Source file location: */home/siguser/workspace/bebot-apps/helloworld*


                                                              --hello.c


When i try to run *bitbake helloworld* from build it throws "Nothing
provides bitbake " error



P.S: My source file location is outside of poky and i gave source
location(S) in helloworld.bb


Any help or ideas?



Regards,

Zafrullah Syed

This sounds like bitbake isn't on your PATH. Have you sourced
oe-init-build-env from the poky directory? Does running `which
bitbake` give any output?

Hi Paul,

I sourced oe-init-build-env and ran *bitbake helloworld *from build
directory*. *Then i get this error. previously, i ran bitbake
core-image-minimal and was successful. No idea where i am doing wrong?

Ok, I guess that it's bitbake itself that throws the error then? Could
you try adding 'inherit externalsrc' to the top of your recipe, that
class is there to prevent do_fetch, do_unpack etc being called which
may be failing as there isn't a SRC_URI set.

Ah no, there is a SRC_URI. But you don't really need it and it's
probably looking in the wrong place for hello.c. The externalsrc class
is designed for this case. See
https://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/classes/externalsrc.bbclass
or the equivalent file in your local clone of poky.

Hi Paul,

I followed this manual
https://wiki.yoctoproject.org/wiki/How_do_I#Q:_How_do_I_put_my_recipe_into_Yocto.3F

and replaced my helloworld.bb file.

Sourced oe-init-build and ran* bitbake gumstix-console-image*

got this error: http://pastebin.com/fxUwQina

Previously, i ran gumstix-console-image successfull but now it breaks.

Any idea about this error?

If you run into a missing dependency, search for it on
layers.openembedded.org:
http://layers.openembedded.org/layerindex/recipes/?q=devmem

Does your bblayers.conf point to the relevant layers?

I'm just guessing here, I'd advise including the beginning of your
bitbake output in any error report as that tells us what layers and
versions your using, what the target and host platforms are, etc.

Add in bblayers.conf

BBLAYERS ?= " \
