README

TileDB GNSS

A package for writing to and reading from TileDB arrays with schemas supporting common GNSS data types.

Dependencies

TileDB-GO

https://github.com/TileDB-Inc/TileDB-Go (depends on C++ library linked below)

Note: Golang and C++ versions must be compatible, check here for compatability

TileDB C++ Library

https://github.com/TileDB-Inc/TileDB

Mac OS X Install C++ Release (version 2.26):

curl --location -o tiledb.tar.gz https://github.com/TileDB-Inc/TileDB/releases/download/2.26.2/tiledb-macos-arm64-2.26.2-30fc114.tar.gz \
&& sudo tar -C /usr/local -xSf tiledb.tar.gz

Mac OS X Build C++ Source (version 2.26):

git clone https://github.com/TileDB-Inc/TileDB.git -b release-2.26
cd TileDB
mkdir build && cd build
cmake -DTILEDB_WERROR=OFF -DTILEDB_VCPKG=ON -DTILEDB_VERBOSE=OFF -DTILEDB_S3=ON -DTILEDB_SERIALIZATION=ON -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
sudo make -j$(sysctl -n hw.ncpu) tiledb install

For Developers

Mac

Add the path to libtiledb.dylib to DYLD_LIBRARY_PATH

LINUX

Add the path to the C++ library to LD_LIBRARY_PATH, commonly located at /usr/local/lib

VSCode
Mac OSX

Add the following parameter to your settings.json file.

"go.toolsEnvVars": {
    "DYLD_LIBRARY_PATH": "$DYLD_LIBRARY_PATH:/usr/local/lib"
},

This assumes libtiledb.dylib is installed in /usr/local/lib
