osgEarth crashes on start up

[bclay1297]

I am able to build osgEarth thanks to Glenn's help but now it crashes on startup. I have tried multiple samples with the same results.
The crash is before it gets to the main of the test app. always in osgEarth.dll. It seems to be related to OSG_INIT_SINGLETON_PROXY(osgEarthFileUtilsGetFullPathInitSingletonProxy, osgEarth::Util::getFullPath(std::string(), std::string()));

When it gets to osgEarth::Util::getFullPath(const std::string& relativeTo, const std::string &relativePath) both variables are empty strings

when it gets to osgEarth::Util::isRelativePath(const std::string& fileName) filename is empty so native is empty and indexing into an empty string causes the crash

Stack trace is shown below

osgEarthd.dll!osgEarth::Util::isRelativePath(const std::string & fileName) Line 171 C++
osgEarthd.dll!osgEarth::Util::getFullPath(const std::string & relativeTo, const std::string & relativePath) Line 264 C++

I have never seen this or seen it reported before.
Do you have the same issue in a RelWithDebInfo configuration?

Glenn:

Thanks for your reply / help.

The RelWithDebug and release works better. They have one startup error ... procedure entry point zip_close could not be located ... osgdb_zip.dll.

The program does come up and display the globe with the warnings shown below. The font file mentioned does exist. grid2.png is in C:\install\data. I do not see what is causing the XML parsing warnings. Some of the apps shut down when I zoom in without explanation.

C:\install\bin>osgearth_map --screen 1 0 --window 1 0 1920 1080 simple.earth

Some server in the map example is just not responding.
Start with the basics instead: osgearth_imgui or osgearth_viewer.

[bclay1297]

I was able to build and run release (non-debug) examples as well. The results are not always what I would expect. I pushed a list of the ones I tested and the results

osgEarth_testResults.txt

I went back to the debug version and ran into problems again with rocksdb.lib. errors like

rocksdb.lib(hash.cc.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in RocksDBCache.obj
4>rocksdb.lib(sharded_cache.cc.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in RocksDBCache.obj
4>

I thought I had made it past those but do not remember how.

You might have internet access problems. Set these env vars are try osgearth_viewer arcgisonline.earth

set OSGEARTH_NOTIFY_LEVEL=INFO
set OSGEARTH_HTTP_DEBUG=1
