Hi,

    I have a whole bunch of projects using Pantheios, but one of
them fails to link on Linux with gcc4.6 with the following error:

In function `pantheios::internal::log_dispatch_3(int, unsigned
int, char const*, unsigned int, char const*, unsigned int, char
const*)':

I'm linking with:

   libpantheios.1.util.gcc46.mt.a
   libpantheios.1.appl.gcc46.mt.a
   libpantheios.1.core.gcc46.mt.a

Please advise,
Thanks,

Glad we sorted it out. Would you mind adding in details of the fix to the 
Pantheios Help forum, and then posting a link to that in this ng?

Thanks

Turns out that in gcc, symbols are only linked forward, so 
dependent symbols in a given lib will only be resolved from the 
libs that follow it in the link list. See here 
<http://stackoverflow.com/questions/45135/linker-order-gcc> for 
some more details.
By moving other statically linked libs to before Pantheios, the 
linker succeeded.
Thanks Matt!
