maplibre-native-qt

MapLibre Native Qt bindings and Qt Location MapLibre Plugin

Important notice: the repository and code have been reorganised for Qt 6.5 support. Version 4.0 is a major release that includes major rendering backend changes. Thus it does not maintain backward compatibility with version 3.x. It is still in active development and API may change before the stable release.

Qt support

This library fully supports Qt 6.5 and newer. Qt 5.15 is fully supported only on desktop platforms, previous Qt 5 versions down to 5.6 only support widgets but not Qt Location.

Get and build

The project uses submodules, so you need to clone it with the following commands:

git clone https://github.com/maplibre/maplibre-native-qt.git
cd maplibre-native-qt
git submodule update --init --recursive

(On some file systems, the submodule update may yield a Filename too long error which can be ignored.)

For more details on building the project, see How to build.

How to use?

Once installed QMapLibre can be used in any Qt and CMake project. Two example projects based on Qt 6 are available in the examples directory.

To build an example, run the following commands:

export QMapLibre_DIR="<absolute-path-to-install>"
cmake --workflow --preset default

or alternatively

mkdir build-example && cd build-example
qt-cmake ../maplibre-native-qt/examples/<example> -GNinja \
  -DCMAKE_C_COMPILER_LAUNCHER="ccache" \
  -DCMAKE_CXX_COMPILER_LAUNCHER="ccache" \
  -DCMAKE_PREFIX_PATH="<absolute-path-to-install>"
ninja
