How do i get iconv.h and other iconv related files. I am trying to compile irmp3 and i get errors such as 

mod_lcdproc.c: In function `mod_lcdproc_setscroller_w':
mod_lcdproc.c:298: warning: passing arg 2 of `libiconv' from incompatible pointer type

and then

mod_lcdproc.o: In function `mod_lcdproc_setscroller_w':
mod_lcdproc.c:(.text+0xc40): undefined reference to `libiconv'
mod_lcdproc.o: In function `mod_lcdproc_init':
mod_lcdproc.c:(.text+0x3744): undefined reference to `libiconv_open'
mod_lcdproc.c:(.text+0x37f4): undefined reference to `libiconv_open'
mod_lcdproc.o: In function `mod_lcdproc_deinit':
mod_lcdproc.c:(.text+0x3984): undefined reference to `libiconv_close'
collect2: ld returned 1 exit status
make[5]: *** [irmp3d] Error 1

I have tried installing libiconv but i still get errors. I believe that uclibc has iconv.h with it but you need locale support. Unfortunately i cant seem to enable locale support in buildroot. Can someone help me please.
Thanks, Rob
