Thanks Octavio,
But I have not clear my main question yet, although you maybe have answered it to me. Do you know why is it needed to add BBCLASSEXTEND = "native nativesdk" in ZLIB recipe? I am using the arm poky toolchain outside bitbake to build the library (generated with bitbake meta-toolchain), and it builds without any problem. Why is it needed to generate a native version of the ZLIB?
Best Regards
Alberto

Makes sense but it is unfortunate.

When bitbake sees the extend, it generates a new recipe which uses the tasks as the same provided by the original .bb file. When it has a 'class-nativesdk' override of a task, this one is used, the same is valid for class-native.
You can grep 'class-nativesdk' in Poky/OE-Core for some examples of this.
