Indeed. Having the cross-compiler include host header files would be
horribly wrong.

Correct. Unless there is a bug, the Eclipse plug-in simply calls the
Buildroot cross-compiler, and the Buildroot cross-compiler already
properly looks in the staging directory (which is its sysroot) for
headers and libraries. I remember testing the Eclipse plugin with
several libraries integrated in the toolchain sysroot, with success.

Oded, can you be more specific about the problems you have seen?

Thanks,

Thomas
