Looking at the installed {{{libiconv}}}:
{{{
$ nm /opt/local/lib/libiconv.a | grep iconv
/opt/local/lib/libiconv.a(iconv.o):
00018c60 D __libiconv_version
00018920 T _iconv_canonicalize
00015f20 T _libiconv
00015f80 T _libiconv_close
00017930 T _libiconv_open
00018150 T _libiconv_open_into
00015fa0 T _libiconvctl
000161e0 T _libiconvlist
/opt/local/lib/libiconv.a(localcharset.o):
/opt/local/lib/libiconv.a(relocatable.o):
000000f0 T _libiconv_relocate
00000000 T _libiconv_set_relocation_prefix
$
}}}
Further, in {{{/opt/local/include/iconv.h}}}:
{{{
#ifndef LIBICONV_PLUG
#define iconv_open libiconv_open
#endif
extern iconv_t iconv_open (const char* tocode, const char* fromcode);
}}}
So there is some trickery going on with respect to the names of functions
from {{{libiconv}}}, but it is not clear to me how to resolve this.
Best regards
