Mac-Build

How to install LROSE source on Mac?

1. Download the lrose-core-20200610.src.mac_osx.tgz tar file.

2. There are two ways to build LROSE:

1. Run the build script:

To build and install into the default directory: /usr/local/lrose

./build_src_release.py

Or set an install directory:

./build_src_release.py --prefix /my/install/dir

2. Using Homebrew formula

• Install prerequisites in a terminal:

brew install cmake

brew install eigen

brew install fftw flex

brew install qt5 netcdf

brew install szip pkg-config

brew install geographiclib

brew install armadillo

brew install libomp libzip

brew install rsync

brew cask install xquartz

• Specify the paths in a terminal:

export PKG_CONFIG_PATH=/usr/local/opt/qt/lib/pkgconfig

export PATH=/usr/local/opt/qt/bin:$PATH

export LROSE_INSTALL_DIR=/usr/local/Cellar/lrose-core/core-20200610

• In a terminal, untar the release and install:

cd ~/Downloads/

tar xvfz lrose-core-20200610.src.mac_osx.tgz

cd lrose-core-20200610.src.mac_osx/codebase/

./configure --disable-dependency-tracking --prefix=$LROSE_INSTALL_DIR

make install

cd ..

rsync -av share $LROSE_INSTALL_DIR

Important Note: Steps 3 and 4 are for the wind analysis tools FRACTL and SAMURAI installation. Users are allowed to skip steps 3 and 4 if they are not in need of these two tools.

3. Build FRACTL:

cd lrose-core-20200610.src.mac_osx/fractl/

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/Cellar/lrose-core/core-20200610/ .

cd ..

4. Build SAMURAI:

• Install prerequisites in a terminal:

brew install cmake

brew install eigen

brew install libomp libzip

brew install llvm

• Install:

export OCFLAGS=`pkg-config --cflags ompi-c`

export OCXXFLAGS=`pkg-config --cflags ompi-cxx`

cmake -DCMAKE_INSTALL_PREFIX=$LROSE_INSTALL_DIR -DCMAKE_MODULE_PATH=$CMAKE_QT5 -D OpenMP_C_FLAGS=$OCFLAGS -D OpenMP_C_LIB_NAMES="" -D OpenMP_CXX_FLAGS=$OCXXFLAGS -D OpenMP_CXX_LIB_NAMES="" .

make

make install
