Comment:

 I setup a bessie32 same config except this time I didn't do


 {{{
 pkg iconv

 }}}

 I have the same issue with her, and doing the hack of below after
 ./configure



 {{{
 rm loader/Makefile.bak
 sed -i .bak 's/ICONV_LDFLAGS= -lc/ICONV_LDFLAGS=-liconv/'
 "loader/Makefile"
 }}}


 works on her as well.


 For completeness from mailing list
 http://lists.osgeo.org/pipermail/postgis-users/2017-November/042494.html

 strk noted this

 {{{
 The code setting ICONV_LDFLAGS, in configure.ac, is as follows:

   dnl libconv defines iconv_open to libiconv_open, so we'll check that
 directly
   AC_CHECK_LIB([iconv], [libiconv_open], [ICONV_LDFLAGS="$ICONV_LDFLAGS
 -liconv" HAVE_ICONV=1], [])
   if test "x$HAVE_ICONV" = "x"; then
     dnl Check for iconv included as part of libc, using iconv_open
     AC_CHECK_LIB([c], [iconv_open], [ICONV_LDFLAGS="$ICONV_LDFLAGS -lc"
 HAVE_ICONV=1], [])
     if test "x$HAVE_ICONV" = "x"; then
       dnl But it's possible this implementation of libiconv doesn't have a
 libiconv_* define
       AC_CHECK_LIB([iconv], [iconv_open], [ICONV_LDFLAGS="$ICONV_LDFLAGS
 -liconv" HAVE_ICONV=1], [])
       if test "x$HAVE_ICONV" = "x"; then
         dnl No iconv library was found; issue a warning to the console
         AC_MSG_ERROR([Could not find libiconv. Please install libiconv and
 libiconv-devel.])
       fi
     fi
   fi

 In order to get just '-lc' you should have found NO `libiconv_open` in
 libiconv,
 while you would have found `iconv_open` in libc.

 But your error message complains about:

   undefined reference to `libiconv_open'

 which you report as being found when you set ICONV_LDFLAGS to -liconv
 ...

 }}}

 So unclear to me why first test fails yet libiconv does have libiconv_open
 evidentally.

 Doing this:


 {{{
 pkg info | grep libiconv
 }}}

 I get:

 {{{
 libiconv-1.14_11               Character set conversion library
 }}}

 Seems to be a common freebsd issue though of all solutions just overriding
 CFLAGS or libs

 All seem like workarounds and not solving the fundamental configure
 failure
