[gentoo-user] Emerge --root= headerfiles taken from / or ROOT?

[Alexander Puchmayr]

Hi there,

I'm just trying setup a small target image with the --root (env SYSROOT), -
config-root and --sysroot options, and some builds fail, because the header 
files as well as cmake include files are not taken from the path specified to 
root/sysroot, but from /.

How can I make emerge/ebuild take the headers from the target path?

The goal is to have a target image, which contains only minimum set of 
packages and also a minimum set of use flags, just to get it booting and fulfill 
its purpose. The use flags and the package set are different from the host build 
system. The architecture is the same, so I'm not cross compiling.

Thanks
