Petros, FYI. gcc also has several different switches for object ouput:
eg. "gcc -c -static ..."
It might help to investigate these options during steps to compile sqlite.c
and your main program to avoid dynamic/static symbol conflicts.
-static
On systems that support dynamic linking, this prevents linking
with the shared libraries. On other systems, this option has no effect.
-shared
Produce a shared object which can then be linked with other
objects to form an executable. Not all systems support this option. For
predictable results,
you must also specify the same set of options used for
compilation (-fpic, -fPIC, or model suboptions) when you specify this
linker option.[1]
-shared-libgcc
-static-libgcc
On systems that provide libgcc as a shared library, these
options force the use of either the shared or static version,
respectively. If no shared version
of libgcc was built when the compiler was configured, these
options have no effect.
There are several situations in which an application should use
the shared libgcc instead of the static version. The most common of these
is when the
application wishes to throw and catch exceptions across
different shared libraries. In that case, each of the libraries as well as
the application itself
should use the shared libgcc.
Therefore, the G++ and GCJ drivers automatically add
-shared-libgcc whenever you build a shared library or a main executable,
because C++ and Java programs
typically use exceptions, so this is the right thing to do.

I have a side question for you, if you can answer.
How did Omilia implement their speaker independent speech recognition
corpus? Was it licensed from elsewhere or developed in house?
