## TODO
#	- May want to supply path to Python instead of, effectively, using result of `which python`
#

## Constants
#
VER="3.5.3"

## Environment
#
export CC=mpicc
export CXXFLAGS="-std=c++11"
export CXX=mpicxx
export LDFLAGS="-L${HDF5_ROOT}/lib" # Need to do this so HDF5 symbols referenced in NETCDF library are found at link time
export LIBS="-lsqlite3 -lhdf5_hl -lhdf5" # Need to do this so HDF5 symbols referenced in NETCDF library are found at link time
export PREFIX="${ISSM_DIR}/externalpackages/gdal/install" # NOTE: Need to export this to properly set destination root for Python libraries on macOS (should not affect Linux build). Set to location where external package should be installed.

# Cleanup
rm -rf ${PREFIX} src
mkdir -p ${PREFIX} src

# Download source
$ISSM_DIR/scripts/DownloadExternalPackage.sh "https://issm.ess.uci.edu/files/externalpackages/gdal-${VER}.tar.gz" "gdal-${VER}.tar.gz"

# Unpack source
tar -zxvf gdal-${VER}.tar.gz

# Move source into 'src' directory
mv gdal-${VER}/* src
rm -rf gdal-${VER}

# Configure
cd src
