[Bug bootstrap/12596] configure setting --with-libiconv-prefix doesn't get passed to gcc-subdir

["artem at bizlink dot ru" <gcc-bugzilla@gcc.gnu.org>]

------- Additional Comments From artem at bizlink dot ru  2004-03-12 08:27 -------
I recently tried to build GCC on FreeBSD-5.2.1 (and with fresh 
autoconf/automake). GCC is "gcc-3.4-20040303".

I have libiconv-1.9.1 port installed (in /usr/local, that is).

Configured with: ../configure --prefix=/usr/local/gcc-20040303-4 --disable-nls 
--enable-languages=c,c++,java --disable-java-awt --without-x 
--enable-threads=posix --with-libiconv-prefix=/usr/local --with-dwarf2

Here is what I see:

intl/config.h - HAVE_ICONV defined!
i386-unknown-freebsd5.2.1/libstdc++-v3/config.h - HAVE_ICONV is not defined.
i386-unknown-freebsd5.2.1/libjava/include/config.h - HAVE_ICONV is not defined.

Trying it by hands:

artem@vg:/tmp/$ cat > test.c              
#line 5280 "configure"

#include <stdlib.h>
#include <iconv.h>
int main() {
iconv_t cd = iconv_open("","");
       iconv(cd,NULL,NULL,NULL,NULL);
       iconv_close(cd);
; return 0; }
artem@vg:/tmp/$ gcc test.c -o test -liconv
/usr/bin/ld: cannot find -liconv
collect2: ld returned 1 exit status
artem@vg:/tmp/$ gcc test.c -o test -liconv -L/usr/local/lib
artem@vg:/tmp/$ ldd test
test:
        libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x28073000)
        libc.so.5 => /lib/libc.so.5 (0x28162000)
8<----------------------->8

It seems the real problem is that gcc on FreeBSD does not include /usr/local/lib 
in linker search path by default.
