How to include a own libary into the toolchain(SDK) for an embeeded Linux generated by Yocto?

How to include a own libary into the toolchain(SDK) for an embeeded Linux generated by Yocto?

[S.Jaritz]

[-- Attachment #1: Type: text/plain, Size: 2052 bytes --]

Hej,

I am looking for an example where is shown how to include an own library 
into the toolchain.

Let's call the library "myLib". For it I created an recipe "myLib.bb" and 
added:

    BBCLASSEXTEND = "native nativesdk"

In my "local.conf" I added:

    IMAGE_INSTALL_append = " myLib"

When building the SDK by:

    $ bitbake myTarget -c populate_sdk

It produces a installer for the SDK and two manifest files. "myLib" is 
only included at the target manifest and not on the host. How can I 
include myLib on the host system?

The idea is, that a other person can build software on his system without 
the Yocto system. Only by using the toolchain he can generate binaries, 
which can be transferred and executed at the evalboard.


Regards!

Like this you can build a myLib-native (for your host - x86) version and
it should be added as an x86 library to your nativesdk.

see:

http://www.yoctoproject.org/docs/2.1/mega-manual/mega-manual.html#var-BBCLASSEXTEND

Do you want myLib-native?

I guess you want something else. You want e.g. the ARM library myLib in
your sysroot plus maybe header files.

What happens if you create a recipe like a testcase for your library
which DEPENDS_append = " myLib" and then you IMAGE_INSTALL_append = "
myLib testmyLib", rebuild the image and populate_sdk?

Thanks for the reply

Like you thought - I want to include the lib + headers.

I included the "myLib" via 

IMAGE_INSTALL_append = " myLib"

and have a project

IMAGE_INSTALL_append = " myProject"

which has in it's recipe

DEPENDS = "myLib"

In my eyes this should be enough.

When looking into the toolchain I found:

myLib.h
myLib.c

but not

libmyLib.so
libmyLib.so.0
libmyLib.so.0.0.0.0
