cannot compile, undefined reference to `libiconv' in libuemf/uemf_utf.c

[insaner]

I've been trying to compile recent revisions, (which I have not done in a long time) but it seems I can't compile. Compilation fails with (present in a few functions, but I only pasted the last one):

libuemf/libuemf.a(uemf_utf.o): In function `U_Utf16leToUtf8':
/fittybones/tmp/compile/inkscape/inkscape/src/libuemf/uemf_utf.c:383: undefined reference to `libiconv_open'
/fittybones/tmp/compile/inkscape/inkscape/src/libuemf/uemf_utf.c:384: undefined reference to `libiconv'
/fittybones/tmp/compile/inkscape/inkscape/src/libuemf/uemf_utf.c:385: undefined reference to `libiconv_close'
collect2: ld returned 1 exit status
make[3]: *** [inkscape] Error 1
make[3]: Leaving directory `/fittybones/tmp/compile/inkscape/inkscape/src'

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/fittybones/tmp/compile/inkscape/inkscape'
make: *** [all] Error 2

as informed to me by suv, EMF/WNF support was merged in 12488, and trying to compile revision 12582 seems to have the same problem and 12482 compiles and runs fine

it seems nobody else is having this problem compiling inkscape, and all I could find online in regards to what this could be is:

http://stackoverflow.com/questions/13180032/undefined-reference-to-libiconv-close
which directs me to this
http://stackoverflow.com/questions/10000925/opengl-linux-undefined-reference-to-basic-functions

saying that the problem is due to link order, where -liconv needs to go after some other library in the compile command. This page:

http://sourceforge.net/p/minidlna/bugs/97/

suggested I run ./configure like this:

./configure LIBS="-liconv"

which did the trick. However, I don't know what to change to make it work permanently. (I know the configure script gets overwritten by autogen.sh, for example, so just adding a line in there won't fix it.)

 Let me know what I have to do. thanks

[Alvin Penner (apenner)]

which rev of devlibs ?

[su_v (suv-lp)]

@insaner - please provide information about OS/distro, and build environment/setup.

[insaner (insaner)]

oh whoops, I knew I was forgetting something:

fedora 14 linux

$ bzr revno
12819

[insaner (insaner)]

sorry, thats fedora 15, not 14

[Alvin Penner (apenner)]

I don't see the devlibs rev number anywhere, am I missing something?

[insaner (insaner)]

suv told me that devlibs is a windows thing, but these issues occur on a linux machine. If devlibs means something else, then I don't really know what that is (other than the gcc, glib, etc versions I provided). Let me know how I can provide the needed info to resolve this. thanks

[Alvin Penner (apenner)]

sorry about that, I didn't realize that devlibs was only for Windows.

[insaner (insaner)]

found this line in m4/iconv.m4

AC_DEFUN([AM_ICONV_LINK],
[
  dnl Some systems have iconv in libc, some have it in libiconv (OSF/1 and
  dnl those with the standalone portable GNU libiconv installed).
  AC_REQUIRE([AC_CANONICAL_HOST]) dnl for cross-compiles

...

I guess this is what I am running into here, but I have no knowledge of autoconf or any of that, and very limited knowledge of make and configure.. so I don't know how to fix this for my system (without breaking it for someone else's).. can someone perhaps shed some light here?

[insaner (insaner)]

hi, please try this patch out, especially if you do NOT have this problem (I want to make sure it doesn't break unaffected systems),
or if you are not running on a linux machine (it seems, macos, hpux and aix have similar checks already in place, if I am not mistaken)

thanks

Patch from comment #9 tested on Crunchbang Waldorf (based on Debian stable), not affected by the bug.
With the patch, Inkscape fails to link with the following error:

-----
...
  CXXLD inkview
  CXXLD inkscape
//usrusr//binbin//ldld:: cannotcannot findfind --liconvliconv

collect2: error: ld returned 1 exit statuscollect2: error: ld returned 1 exit status
...

[insaner (insaner)]

ok, just for the sake of anyone else running into this same problem, (in trying to compile anything else, not just inkscape).

it seems for me it was caused by some stray:
     /usr/local/include/iconv.h

which included this line:
#define iconv_t libiconv_t

which is what i believe is directly responsible for this.

 I just renamed it to
     /usr/local/include/iconv.h-NO

and inkscape compiles fine now.. no hacking necessary.

where this file came from, I am not sure.. and rpm isn't giving me any clues. Hope that helps someone out there
