your understanding is correct, however ........ iconv() is part of glibc but it relies on all of the gconv shared libs found in /usr/$CTARGET/usr/lib/gconv/ to do its actually work. which we also incidentally delete when building the cross-compiler glibc (see src_install.eblit and look for "gconv"). you aren't the first person to find this behavior undesirable, and when i implemented it, it was more of "let's save space on things i don't think anyone will use". but if people are using it, then installing these things probably makes sense. -mike
