built-in spatialindex conflicts with external libspatialindex

Author Name: rustychris - (rustychris -)
Original Redmine Issue: 3507
Affected QGIS version: master
Redmine category:python_plugins

---

libspatialindex is used by the python rtree module, but when this module is loaded from within a QGIS python plugin, the symbols from the builtin copy of spatialindex collide and render the python rtree module inoperable.

How to reproduce: install the rtree python module. Start QGIS and open a python console:

>>> import rtree
>>> p = rtree.index.Property()
>>> p.set_storage(0)
True
>>> p.get_storage()
1
>>>

Stepping through in gdb shows that libspatialindex.so:Tools::PropertySet::getProperty is shadowed by a function of the same name in libqgis_core.so.

By updating the [[SpatialIndex]] wrapper and amending CMakeLists and creating a Cmake script, I managed to build QGIS with a systemwide libspatialindex.

Wonder proposed to update the shipped copy of [[SpatialIndex]] and update the wrapper, so the user has the choice to use either lib.

Doing so, would help your problem, I suppose.

I can provide a patch, but I'm not a 100% sure, everything works correct or that my patch is sound, as I am no C++ programmer. Maybe we should do that after 1.7.

Hello, bug triage...

with QGIS 2.13 on Debian, there is no conflict: p.get_storage() returns 0.

I am closing this bug.
