>>Do I have to set some conditional compile anywhere or is there a later version of ElPack? <<<br />No. You don't have either latest sources installed (the .9 source code was updated after our announcement) or you have configuration mix up. This error can happen with a previous source code version only.
When you don't want to use precompiled installer: 1.) Get latest source installer 2.) After installation add source code path to the library path (this is not done automatically by installer. Don't use any other option in installer). 3.) Load and compile the _LMDElPack_d16 project group.
