The dependency_libs variable is empty, which is where I would naively expect to find it listed. (In fact all the variable are empty, except old_library='liburjtag.a' and libdir='/usr/local/lib'.) Unless I'm missing something, it appears that including ftd2xx.lib doesn't define any symbols (which makes sense to me, because there's no compilation involved in creating an archive, so how could it resolve symbols?), nor does it put ftd2xx.lib into the archive in any way. ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
