[Octave-bug-tracker] [bug #59968] ld: symbol(s) not found for architecture x86_64

[david laxer]

Follow-up Comment #15, bug #59968 (project octave):

I made progress building octave on OS X 10.11.7.
However, I'm still getting 

Undefined symbols for architecture x86_64:
  "_iconv", referenced from:
      _mem_cd_iconveh_internal in libgnu.a(striconveh.o)
      _iconv_carefully_1 in libgnu.a(striconveh.o)
     (maybe you meant: _str_iconveha, _str_cd_iconveh , _mem_cd_iconveh ,
_octave_iconv_close_wrapper , _mem_iconveh , _iconveh_close , _iconveh_open ,
_octave_iconv_open_wrapper , _str_iconveh , _mem_iconveha )

      _octave_iconv_close_wrapper in

     (maybe you meant: _octave_iconv_open_wrapper)
ld: symbol(s) not found for architecture x86_64


If I add -Wl,-force_load,/usr/lib/libiconv.2.dylib
to the linker line, it builds.

Here's my configure command:
