DOLFIN User ManualHoffman, Jansson, Logg, WellsB.1.4Compiling the demo programsAfter compiling the DOLFIN library according to the instructions above, youmay want to try one of the demo programs in the subdirectory src/demo/of the DOLFIN source tree. Just enter the directory containing the demoprogram you want to compile and type make. You may also compile all demoprograms at once using the command# make demoB.1.5Compiling a program against DOLFINWhether you are writing your own Makefiles or using an automated buildsystem such as GNU Autotools or BuildSystem, it is straightforward to compilea program against DOLFIN. The necessary include and library pathscan be obtained through the script dolfin-config which is automaticallygenerated during the compilation of DOLFIN and installed in the bin subdirectoryof the specified with --prefix. Assuming this directory isin your executable path (environment variable PATH), the include path forbuilding DOLFIN can be obtained from the command# dolfin-config --cflagsand the path to DOLFIN libraries can be obtained from the command# dolfin-config --libsIf dolfin-config is not in your executable path, you need to provide thefull path to dolfin-config.Examples of how to write a proper Makefile are provided with each of theexample programs in the subdirectory src/demo/ in the DOLFIN sourcetree.102
