Undefined symbol: _ZNK6google8protobuf11MessageLite17SerializeToStringEPSs

[GPB]

What steps will reproduce the problem?

My aim is to use Google Proto buff on VxWorks for C++. I ran below
commands on cygwin in Windows7 machine.
*) ./configure --target=powerpc-wrs-vxworks --enable-static=no --
disable-shared --with-protoc=protoc --enable-Multithreading
*) make
*) This generated 3 .a files in "protobuf-2.2.0\src\.libs". They are
libprotobuf.a, libprotobuf-lite.a and libprotoc.a

Now I wanted to use these .a files (lib files) in my software to
encode using GPB. So I copied these library files and I tried to build
using scons in my package.


What is the expected output? What do you see instead?
I expected the scons to build smoothly. But it came with below issues
and scons build failed.

*) Undefined symbol:
_ZNK6google8protobuf11MessageLite17SerializeToStringEPS
I understand that this symbol is defined in
message_lite.cpp

What version of the product are you using? On what operating system?

2.2.0, installed over cygwin in Windows 7 and configured with
/configure --target=powerpc-wrs-vxworks --enable-static=no --
disable-shared --with-protoc=protoc --enable-Multithreading
