If attempting to use system-installed LLVM compiler, make sure to build boost, MPI, etc.

You may alternately choose to satisfy Dakota's requirements via your package manager such as Fink, Homebrew, MacPorts, etc., but must use a consistent toolchain throughout the TPL and Dakota build processes.

Moreover, not all Dakota packages (most notably Acro) support LLVM/Clang, which is the default system compiler in more recent versions of OS X.

Take care not to errantly configure Dakota with a mixture of system-provided gcc or clang, and your custom-installed tools.

Apple provides C and C++ compilers with the operating system and XCode Command Line Tools however they do not offer a Fortran compiler, and it can be challenging to install a compatible one.OpenMPI: compile from source if desired.Linear Algebra: stock OS X vecLib Framework suffices.Boost 1.50.0 or newer (1.53.0 recommended): compiled from source using the above compilers (not system compilers).GNU compilers, including gcc, g++, and gfortran from.CMake 2.8.12 or newer: install DMG binary.It is necessary to instruct brew to build Boost from source using the gcc-5 compiler.īrew install -build-from-source -cc=gcc-5 Optional (needed for message-passing parallelism): Install OpenMPI 1.6, building it from source, too.īrew install -build-from-source -cc=gcc-5 Optional (needed to use bayes_calibration queso): GSL 1.16 from source.īrew install -build-from-source -cc=gcc-5 Using the Historical MethodĪn example system setup process follows. In general, we satisfy Dakota's requirements with the following: Install which includes all needed compilers, with the commandīrew install Install CMake with the command.Follow the instructions on the homebrew website to install the homebrew package manager.All libraries and tools will be installed using the homebrew package manager.

Verified September 2017 on OS X Sierra 10.12. It may be necessary in addition to enable C++11 when compiling Boost, particularly with GCC compilers. Also make sure if you build your own toolchains that the TPLs are built with the compiler you intend to use for Dakota and not the system compiler. Notes: Mac SIP can be highly problematic when running Dakota tests or even using the Dakota binaries. Downloading and installing all required dependencies spearately.This is the easier option for most users. The Dakota team has discovered two methods of installing Dakota's dependencies on OS X.
