Optware ipkg installs libs to /opt/lib, which is not a usual place that the system automatically looks for shared lib. You can work around that with LD_LIBRARY_PATH environment variable; or you can add "-rpath /opt/lib" to your ld command line, or "-Wl,-rpath,/opt/lib" if you use gcc to link.
We recommend to use optware development framework and create ipk. This kind of problem has already been taken care of in the framework. And your work can very likely be re-used for other optware targets. In the case of optware, we don't always package development headers, since they are staged in the staging directory.
