iconv / LDFLAGS question (opensolaris)

[Mark Mayo <mark%vmunix.com@localhost>]

Hi there, I'm using pkgsrc on OpenSolaris (b56) and have run into
various problems where configure scripts are picking up the GNU libiconv
in /usr/local (my LOCALBASE) that got pulled in as a dependency but
then are not linking properly. Using shells/zsh-current as an example
(I've also encountered this with graphics/gd and print/teTex3-bin so
far) I can see:

the gnu libiconv header get picked up:

        checking iconv.h usability... yes
        checking iconv.h presence... yes
        checking for iconv.h... yes

and later:

        checking for iconv... yes
        checking whether _libiconv_version is declared... yes
        checking for libiconv in -liconv... no
        checking for iconv declaration... const

and I end up with this as it's compiling:

gcc -Wl,-R/usr/local/lib   -o zsh main.o  `cat stamp-modobjs`   -lsocket
-ldl -lnsl -lcurses -lm  -lc
Undefined                       first referenced
symbol                             in file
libiconv_close                      utils.o
libiconv_open                       utils.o
libiconv                            utils.o
ld: fatal: Symbol referencing errors. No output written to zsh
collect2: ld returned 1 exit status

[wrapper.sh] note: The real command line, after the pkgsrc wrapper, was:
/export/pkgsrc/shells/zsh-current/work/.gcc/bin/gcc -Wl,-R/usr/local/lib
-o zsh main.o builtin.o compat.o cond.o exec.o glob.o hashtable.o hist.o
init.o input.o jobs.o lex.o linklist.o loop.o math.o mem.o module.o
options.o params.o parse.o pattern.o prompt.o signals.o signames.o
string.o subst.o text.o utils.o watch.o
-I/export/pkgsrc/shells/zsh-current/work/.buildlink/include
-L/export/pkgsrc/shells/zsh-current/work/.buildlink/lib  -lsocket -ldl
-lnsl -lcurses -lm -lc


So I think I know what it's doing, and if I build zsh manually from the
tarball I can simply "force" the linker's hand by setting some
LDFLAGS. I tried this via export and via the port's Makefile:

LDFLAGS+=       /usr/local/lib/libiconv.so -R/usr/local/lib

But I get:

-R/usr/local/lib -Wl,-R/usr/local/
lib conftest.c
-I/export/pkgsrc/shells/zsh-current/work/.buildlink/include  -liconv



I'm guessing the -liconv was the first "linker test" looking for
-liconv.

Any suggestions on how to properly deal with this? I'm sorry but I'm
completely new to pkgsrc and my Makefile skills are very rusty,
otherwise I'd have made more progress with understanding how things
come together.. Except for the libiconv problem, I've built about 100
ports now with the stock gcc compiler in /usr/sfw/bin and things have
been working well.

Thx,
-Mark
