Build Error in Latest Git

[Noah Lavine]

Hello all,

I got the following build error after I pulled the latest git version of Guile:

<a bunch of stuff that seems irrelevant here>
CCLD   libguile-2.0.la
Undefined symbols:
  "_iconv", referenced from:
      _rpl_iconv in libgnu.a(iconv.o)
     (maybe you meant: _mem_iconveh, _iconveh_close , _rpl_iconv_open
, _mem_cd_iconveh , _str_iconveh , _rpl_iconv , _iconveh_open ,
_rpl_iconv_close , _str_cd_iconveh )
  "_iconv_close", referenced from:
      _rpl_iconv_close in libgnu.a(iconv_close.o)
     (maybe you meant: _rpl_iconv_close)
  "_iconv_open", referenced from:
      _rpl_iconv_open in libgnu.a(iconv_open.o)
      _rpl_iconv_open in libgnu.a(iconv_open.o)
     (maybe you meant: _rpl_iconv_open)
ld: symbol(s) not found
collect2: ld returned 1 exit status

This continued even when I rebuilt everything starting from autogen.sh.

It looks like a link error involving gnulib and libiconv, but I'm not
sure how to debug it. My libiconv is up-to-date, and everything built
fine before I pulled.

Thanks
Noah

Odd. On what platform is this?

Mac OS X 10.6. There's some weirdness because I have two versions of
libiconv installed - the one that comes with OS X, and one from
Macports. They also define different symbols for the same functions -
the regular OS X library has "_iconv_close", and the Macports one has
"_libiconv_close". I wonder if this is a case of the configure script
picking up one set of names and then linking with the other set.
(Although that doesn't explain why it used to build, back when I had
the same setup.)

I've tried building with both of those libraries, using
--with-libiconv-prefix to switch, and I get the same error. (I started
with 'make distclean' each time.)

After looking at this a bit more, I think it's an issue with Gnulib,
or possibly the configuration system. I'd like to report it to one of
those projects, but could someone tell me how Guile's configuration
mechanism interacts with Gnulib's? I don't really understand what is
configuring Gnulib, since it has no configure script.

Thanks,
Noah

Gnulib is a library of source files, including C files, Autoconf macros,
etc.

Guile uses Gnulib’s ‘libunistring’ module, which in turn depends on the
‘iconv’ module (see m4/gnulib-cache.m4 in the Guile tree).  The latter
is the one that provides the ‘--with-libiconv-prefix’ configure option
and the $(LTLIBICONV) variable used in libguile/Makefile.am.  On non-GNU
systems, that variable should be non-empty.

Hopefully this is enough info to ping bug-gnulib@gnu.org.  :-)

Thanks,
Ludo’.

Yeah, to be honest I don't really understand it very well either; but
given that I can't find the string "iconv" in our configure.ac, I don't
think it would be remiss to send a report to bug-gnulib@gnu.org
(possibly copying this list too).

Cheers,

Andy

Hi again,

FWIW the problem is also visible here on FreeBSD and Darwin:

Make sure to build with “make V=1”, to get the full command lines in
the log.

Can you also check all the things related to iconv in config.log?

Thanks,
Ludo’.
