NextGIS QGIS

Intro

:four_leaf_clover: NextGIS QGIS build using NextGIS Borsch.

This simplified and reorganized repository of original QGIS with NextGIS additions needed by network installer.

Update sources

To update sources from original QGIS repository:

1. Update diff files from pevious release:

python create_patch_batch.py --src_dir <some dir> --dst_dir <some dir>

2. Get latest release from QGIS Repository releases
3. Extract it to <path to QGIS sources>
4. Execute command in borsch opt directory:

python tools.py organize --src /<path to QGIS sources>/QGIS --dst_path <path to NextGIS QGIS sources>

In opt directory of this repository there is several files which interfere on sources merging process:

• folders.csv - list of original directories to merge
• postprocess.py - script executed after successfully merging (name is constant for tools.py)

Postprocess copying files (with paths) from opt/overwrite to the root of repository. Files with same names and paths overwrite. For opt/patches directory all patch files apply.

Customization details

For modifications see patches at opt directory.

To add some QGIS components:

1. Add component path to folders.csv or remove skip mark if path already in this file. Check the all extensions/file names are in this row.
2. Add or modify CMakeLists.txt. For plugins you only need to add new directory name to plugins list (i.e. providers).
3. Check additional resources (images, databases or other files) which needed by component, are imported from original sources and install in target system via cmake install target.
4. Add modified files to list in create_patch_batch.py.

Some dependencies are removed:

• Flex and Bison not needed to build QGIS. Only to update/regenerate flex and byson lexer/parser files. To do it use following command

cmake -DOSX_FRAMEWORK=ON -DWITH_BINDINGS=ON -DPREPARE_ONLY=ON -DCMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -DCMAKE_OSX_DEPLOYMENT_TARGET=10.14 -DWITH_PROJ_EXTERNAL=ON -DWITH_GDAL_EXTERNAL=ON -DWITH_Qt5_EXTERNAL=ON -DWITH_GEOS_EXTERNAL=ON  -DWITH_Qca_EXTERNAL=ON -DWITH_QtKeychain_EXTERNAL=ON -DWITH_SpatialIndex_EXTERNAL=ON -DWITH_SQLite3_EXTERNAL=ON -DWITH_Spatialite_EXTERNAL=ON -DWITH_LIBZIP_EXTERNAL=ON -DWITH_EXPAT_EXTERNAL=ON ..
cmake --build . --config release --target prepare_parser
cmake --build . --config release --target synccrsdb

• Spatial reference system database already filled and not generate in normal build.
• Drop GPX, babel, VectorTiles, GeoCMS, Server, Android, QField, ArcGIS, json parser from thirdparty, EXIV2 ...
