compiling a native (x86) application using Yocto

compiling a native (x86) application using Yocto

Hi,

I am trying to compile a native tool/application using Yocto.

I have added BBCLASSEXTEND = "native" to the recipe. The compilation goes thru fine. But, in do_package_qa it is running a strip command using arm-linux-gnueabihf-strip, which is failing because the application is compiled using gcc. Do I have to anything else to fix of this issue?

Regards,
Sajesh

Strange, that should be enough... Care to share the recipe?

BBCLASSEXTEND = "native"

Sajesh,

It appears your Makefile directly calls native gcc to produce x86 binary.

Now, BBCLASSEXTEND allows you to "extend" a regular target recipe that 
produces an ARM binary to also produce a native x86 binary. Naming your recipe 
as something-native.bb doesn't change the procedure.

So, it first builds and strips an ARM binary and then would have done the same 
for x86 binary. But since you set GCC=gcc in your Makefile, it chokes on the 
ARM-stripping step.

Now, if you only want a native recipe, instead of BBCLASSEXTEND, you should 
just do "inherit native" and that class would short-circuit all the target 
build and strip tasks.
