[Boost-users] Re: serialization example linker errors.

This problem remains in the boost_1_32_0 release, and is slightly more 
complex/different than I've previously reported.

I got all the serialization examples to build by:
   1.  Placing /usr/lib/libm.a on my system.  The static development 
libraries where not on by default.
   2.  Putting a <library-file>/usr/lib/libpthread.a statement in the 
requirements section of the common rule defined in the Jamfile.

This brings up a number of questions:

First, is it possible to mix static and shared libraries?  In attempting 
to use libpthread.so instead of libpthread.a, These errors occurred:
/lib/libpthread.so.0: undefined reference to `_errno_at_GLIBC_2.0'
/lib/libpthread.so.0: undefined reference to `_h_errno_at_GLIBC_2.0'

I've attempted to add /usr/lib/glib-2.0.so, but this has no affect.

Second, where did the requirement to have libm.a come from?  Neither the 
serialization library Jamfile or the example Jamfile makes reference to it.

Last, I see that the serialization library Jamfile has a 
<runtime-link>static/dynamic statement in its default build section.
So why isn't there a shared library for serialization?

FYI.  I've switched to gcc v3.4.3 recently.  Everything that I know 
about involving the boost libraries remained the same.
