= Compiling the PDAF library = The tutorial implementations in the directory `tutorial/` and the models implemented with PDAF in `models/` are setup to compile the PDAF library when the application is compiled. The PDAF library, thus the core routines of PDAF and PDAF-OMI, can also be compiled separately. This is the common approach when one implements PDAF with some models in the online-coupled setup (see e.g. the directory `modelbindings`). == Compiling PDAF for ensemble filters and smoothers == To compile PDAF for ensemble filters and smoothers, do the following: == Compiling PDAF for 3D-Var methods == The 3D-Var methods implemented in PDAF use solver algorithms from external libraries (from the driectory `external/`). To compile PDAF with full support for the 3D-Var schemes do the following:
