Hello Scott,

Thanks for your report!

I guess your system lacks the gconv libraries. For example, in the
CodeSourcery toolchains, there are :

thomas at skate:~/x-tools/arm-2011.03$ find . | grep gconv
[...]
./arm-none-linux-gnueabi/libc/usr/include/gconv.h
./arm-none-linux-gnueabi/libc/usr/lib/gconv
./arm-none-linux-gnueabi/libc/usr/lib/gconv/IBM939.so
./arm-none-linux-gnueabi/libc/usr/lib/gconv/CP1257.so
./arm-none-linux-gnueabi/libc/usr/lib/gconv/ISO8859-13.so
./arm-none-linux-gnueabi/libc/usr/lib/gconv/GBK.so
./arm-none-linux-gnueabi/libc/usr/lib/gconv/EBCDIC-DK-NO.so
./arm-none-linux-gnueabi/libc/usr/lib/gconv/ISO8859-6.so
./arm-none-linux-gnueabi/libc/usr/lib/gconv/CP1258.so
./arm-none-linux-gnueabi/libc/usr/lib/gconv/MAC-UK.so
./arm-none-linux-gnueabi/libc/usr/lib/gconv/LATIN-GREEK-1.so
[...]

And Buildroot does not copy those files to the target automatically.
Maybe we need to extend the toolchain mechanism a bit to provide an
option to copy those files. Copying them all unconditionally is
unfortunately not really an option: the complete gconv directory
contains ~9 MB of libraries.

Which toolchain are you using ?

Regards,

Thomas
