# Building gdal on Mac OS X

The following procedure has been adapted form the [GDAL CI](https://github.com/OSGeo/gdal/blob/master/ci/travis/osx/before_install.sh).

```bash
set -e

xcode-select --installs

brew install cmake
brew install proj
brew install boost
brew install swig
brew install sqlite
brew install thrift
brew install --cask miniconda

git clone git@github.com:OSGeo/gdal.git
git checkout v3.6.4

conda update -n base -c defaults conda
conda install -y compilers automake pkgconfig cmake
conda config --set channel_priority strict
conda install --yes --quiet proj=7.1.1=h45baca5_3 python=3.8 swig -y
conda install --yes --quiet libgdal=3.1.4=hd7bf8dc_0  --only-deps -y

CONDA_PREFIX=/usr/local/miniconda/envs/test
find ${CONDA_PREFIX}/lib -name '*.la' -delete

mkdir build
cd build

CFLAGS="-Wextra -Werror -Wunused-variable" CXXFLAGS="-Wextra -Werror -Wunused-variable" cmake .. \
        -DCMAKE_INSTALL_PREFIX=$HOME/install-gdal \
        -DCMAKE_PREFIX_PATH=${CONDA_PREFIX} \
        -DGDAL_USE_GEOTIFF_INTERNAL=ON \
        -DGDAL_USE_PNG_INTERNAL=ON \
        -DGDAL_USE_POSTGRESQL=OFF \
        -DGDAL_USE_WEBP=OFF \
        -DGDAL_USE_ARROW=OFF \
        -DGDAL_USE_PARQUET=OFF \
        -DBUILD_CSHARP_BINDINGS=OFF
make -j3
make install
```

After this, the library can be found in `~/install-gdal/share/java/libgdalalljni.dylib`.

When starting a java application, the library can be loaded with the following command:

```bash
java -Djava.library.path=~/install-gdal/share/java -jar myapp.jar
```
