[tlbuild] missing libiconv when compiling xdvik on FreeBSD

[Mojca Miklavec]

Hi,

I believe that the problem lies in texk/xdvik/m4/xdvi-check-iconv.m4.
The log from configuring xdvik says:

checking for iconv.h... yes
checking for library containing iconv... none required
checking for iconv input type... char **

There is this part of code that I don't entirely understand (or
rather: didn't yet take enough time to decrypt it):


AC_LANG_CONFTEST([AC_LANG_PROGRAM([[#include <stdlib.h>
#include <iconv.h>]],
                                  [[iconv_t cd = iconv_open("","");]])])
xdvi_cv_search_iconv=no
for xdvi_lib in "" -liconv -lrecode; do
  LIBS="$xdvi_lib $xdvi_iconv_save_LIBS"
  AC_LINK_IFELSE([],
                 [xdvi_cv_search_iconv=$xdvi_lib
                  break])
done
test "x$xdvi_cv_search_iconv" = x && xdvi_cv_search_iconv="none required"
LDFLAGS=$xdvi_iconv_save_LDFLAGS
LIBS=$xdvi_iconv_save_LIBS])
]) # _XDVI_ICONV_LIB


but I suspect that the code is trying to compile with "-liconv" which
succeeds and then somehow concludes
    xdvi_cv_search_iconv="none required"

and doesn't add any iconv flag like it should.

What's the current upstream tracker for xdvi?
