Hi Gordon, bug-libtool members - this is my first post to this list,
so please reply to : jason.vas.dias <at> gmail.com

I believe I may have found a libtool (or possibly a libtool-triggered
glibc or binutils) bug :

In a "setarch i686" environment on a linux-x86_64 host, where
EVERYTHING (more or less) is at the latest
available stable upstream version - especially :

$ setarch i686
$ echo eval $(echo "307  export CC=/usr/bin/gcc' -m32'
  308  export GCC=/usr/bin/gcc' -m32'
  309  export CXX=/usr/bin/g++' -m32'
  310  export LD=/usr/bin/ld' -melf_i386'
  311  export AS=/usr/bin/as' -32'

I do for instance :

$  /usr/src/poppler/configure --prefix=/usr --libdir=/usr/lib32
....

but make fails :

$ make
  CXXLD  libgoo.la
Inconsistency detected by ld.so: dl-deps.c: 622: _dl_map_object_deps:
Assertion `nlist > 1' failed!
make: *** [libgoo.la] Error 127

but I can do:

$ cd goo/.libs

libgoo.so: ELF 32-bit LSB shared object, Intel 80386, version 1
(SYSV), dynamically linked, not stripped

So what is libtool trying to do here that my command isn't ?

Whatever it is, glibc-2.13 doesn't like it, or it caused binutils to
produce a nasty object that glibc doesn't like.

Any advice / suggestions would be much appreciated. Obviously, I'll
have to 'strace -f -e trace=execve make' . If you'd be interested in
the log, I'll post it.

Incidentally, I had to :
$ rm ./libtool
after the poppler configure, else I got lots of errors :
$ make -j2
make  all-recursive
make[1]: Entering directory `/tmp/poppler'
Making all in goo
make[2]: Entering directory `/tmp/poppler/goo'
  CXX    gfile.lo
  CXX    gmempp.lo
../libtool: line 42: -32: command not found
../libtool: line 42: -32: command not found
  CXX    GooHash.lo
../libtool: line 42: -32: command not found
  CXX    GooList.lo
../libtool: line 42: -32: command not found

But if I remove what was generated during configure as ../libtool
(from goo/) , no such messages appear.

Thank you for the otherwise great libtool and in advance for any replies !
All the best,
Jason
