I think we now found a solution on how to get around this. We created a small library which defines 'operator delete(void*, size_t)' and use a version script to annotate it with the Qt5 'namespace'. Then we only have to make sure it's loaded before libEsriCommonQt.so and all is fine. But the question persists - why does libQtCore5.so provided by TQtC (compiled with c++14 according to Coin logs) export this symbol whereas the one from openSuSE does not (openSuSE even compiles with c++17, according to build.opensuse.org logs) ...

What we're doing is more or less something like qid = GraphicsLayer::addGraphic(m_graphicPtr); ... modify m_graphicPtr (change geometry or smth. else) ... GraphicsLayer::updateGraphic(gid, m_graphicPtr); ... do more modifications ... GraphicsLayer::updateGraphic(gid, m_graphicPtr); ... This does lead to race conditions because the render thread is accessing attributes of m_grpahicPtr  while we're modifying those attributes. Our solution is exactly what you're proposed - using addGraphic(), working on a new (cloned) graphic for hte changes and then call updateGraphic() with new graphic. Thx, Christian ... View more

Ok, it looks like my assumption about ownership is wrong. I moved the code into a small testcase and calling updateGraphic() in a loop (via timer every 10ms) it's crashing now and then but everytime with a similar backtrace. If you're interested in this backtrace or the testcase, please let me know. ... View more

Hi, thx for your suggestions. not setting TileInfo::format and TileInfo::spatialRefernce does work as long as Layer::setDefaultSpatialRefernce is called.It would still be nice to complete the TileInfo api TiledMapServiceLayer::initialize() is called as soon as I call Map::addLayer().call stack: Map::add_layer(EsriRuntimeQt::Layer*) Map_impl::add_layer(EsriRuntimeQt::Layer*) Map_impl::internal_add_layer_(EsriRuntimeQt::Layer*) When I do not overwrite initialize() and call initialize() after the xml was parsed, I get an error (Layer already initialized) - so it looks like initialize() must be intercepted until the xml is available When I overwrite initialize() to call call the base class impl it seems to work - I thought I checked this yesterday and it did not work... strange but this would be a correct async operation then Why do we need TiledMapServiceLayer::setUrl() then? Calling initialize() two times does not work so I think using another url will not work either... at least it should not work as soon as the layer is initialized. I've attached the current version, please have a look ... View more
