msdos_conv_utf8.c:(.text+0x3c0): undefined reference to `iconv'

[Sebastian Huber]

Hello,

the UTF-8 support is only available for the latest Git master.  On RTEMS 4.10 
it is not available.

In Newlib you have to enable the specific language support, e.g.

iconv_encodings=big5,cp775,cp850,cp852,cp855,\
cp866,euc_jp,euc_kr,euc_tw,iso_8859_1,iso_8859_10,iso_8859_11,\
iso_8859_13,iso_8859_14,iso_8859_15,iso_8859_2,iso_8859_3,\
iso_8859_4,iso_8859_5,iso_8859_6,iso_8859_7,iso_8859_8,iso_8859_9,\
iso_ir_111,koi8_r,koi8_ru,koi8_u,koi8_uni,ucs_2,ucs_2_internal,\
ucs_2be,ucs_2le,ucs_4,ucs_4_internal,ucs_4be,ucs_4le,us_ascii,\
utf_16,utf_16be,utf_16le,utf_8,win_1250,win_1251,win_1252,\
win_1253,win_1254,win_1255,win_1256,win_1257,win_1258

"$source_dir/configure" \
[...]
	--enable-newlib-iconv \
	--enable-newlib-iconv-encodings=$iconv_encodings \
