[Buildroot] missing iconv.h

[Christopher Pfindel]

Hi there,

I'm trying to compile buildroot with toolchain on target.
While compiling gcc for the target I think, I get the following error:

So iconv.h seems to be missing.
Searching for iconv.h I found it in

/usr/include/iconv.h
.../rtai_toolchain_build_i686/uClibc-0.9.30.1/include/iconv.h
.../rtai_build_i686/libiconv-1.12/include/iconv.h
Should it appear anywhere else?

How can I get rid of this error?
Thanks for all the help.
