[postgis-devel] [postgis-users] Compiling PostGIS under FreeBSD 11

[Regina Obe]

strk already knows this, but for others.

As noted in https://trac.osgeo.org/postgis/ticket/3936

I found a cleaner work around which works on both bessie and bessie32 (both FreeBSD 11.1s)

sh autogen.sh
./configure --with-projdir=/usr/local --with-libiconv=/usr/local

Soon I'll be able to put them in our chain of testing once we figure out this 32-bit freebsd brin  mystery

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 my question is: do you have multiple libiconv.so files on the system ?
