[Click] failed to load dynamic lib

[Peter De Cleyn]

Hi all,

I try to build a click configuration with some elements interfacing
with libiw. Although I managed to get these up and running a while
ago, I keep getting undefined symbols errors when loading the script
in to userspace mode. The machine I tried it on has recently crashed
completely, so I installed it from scratch and maybe I forgot
something ...

The elements are in a separate dir in the elements dir. In order to
link all object files to the package mip.uo, the make file executes as
last

 g++ -W -Wall -fno-exceptions -fno-rtti  -shared -L/usr/lib -o mip.uo 
 assowatch.uo binding.uo ... upackage.uo -liw

which should link with the libiw if I'm not mistaken. assowatch is the
element which needs the libiw

ldd mip.uo gives:
        libiw.so.25 => /usr/lib/libiw.so.25 (0x4002b000)
        libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x40031000)
        libm.so.6 => /lib/i686/libm.so.6 (0x400e3000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x40105000)
        libc.so.6 => /lib/i686/libc.so.6 (0x4010f000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

which seems ok, but executing a script with the mip package gives me:

While loading package `mip':
  package /usr/local/lib/mip.uo: undefined symbol:
_Z16iw_print_timevalPcPK7timeval
requirement `mip' not available

Compiling a standalone application with libiw support is not a
problem, so I don't think its a problem of library installation.

Can anyone help me with this or tell me what the exact procedures are
to create elements that link with a shared liabrary?

thanks for reading this!

Peter
