- Version:
MapServer 7.6
Overview¶
MapServer, at least since 7.4.0, does not compile if disabling GDAL or PROJ support. As far as we know, nobody complained about that, which shows that such configurations must have been used very rarely in practice. We thus propose to acknowledge the fact that those dependencies as required. Beyond the benefit of avoiding broken configurations, this also removes a huge number of #ifdef that are scattered in the source code, which improves readability.
Proposed solution¶
In CMakeLists.txt, remove USE_GDAL, USE_OGR, USE_PROJ
In CMakeLists.txt, make GDAL and PROJ required as libpng, libjpeg and freetype
In .c, .cpp files, remove the code paths that correspond to USE_GDAL, USE_OGR, USE_PROJ not defined
Backwards Compatibility Issues¶
None w.r.t 7.4 branch.
Security implications¶
None.
MapScript implications¶
None (apart a removal of a #ifdef USE_PROJ in PHP bindings)
Documentation needs¶
https://mapserver.org/installation/unix.html and https://mapserver.org/installation/win32.html will need to move GDAL and PROJ from the highly recommended section to the mandatory one.
