Thanks Marcus. The dependency of UHD on boost is not an issue; if they are both installed from Ubuntu packages, they link without a problem. The problem was that my code, compiled on one machine, did not link (wrong .so files) with a different version of boost. I think that I can fix that in my C++ client by removing the depenency on boost in my code.
This still leaves another binary compatibility problem that I encountered, that gcc in different versions of Ubuntu generates different symbols for C++ functions, causing linking problems when an .so file from one version of Ubuntu is used on another version. Hopefully the move to the C API will resolve the second problem. The first is indeed easier to solve.
