Re: GetText 1.20.1 and libgettextlib.so: undefined reference to `libiconv' (and friends)

Hi Jeffrey,

It is pointless to patch Makefile.in files, since these are generated from
Makefile.am files.

On NetBSD, which has iconv() in libc, it is normal that LIBICONV and
LTLIBICONV are set to empty.

However, if you are using GNU libiconv's <iconv.h>, LIBICONV and
LTLIBICONV need to contain "-L<path> -liconv -Wl,-rpath,-<path>".
If not, you need to take a look in config.log, to determine why not.

gnulib/modules/localcharset-tests does not reference $(LIBICONV), because
the test code test-localcharset.c does not make use of iconv(). How come
that you get a link error for test-localcharset?
