3.3: stack smashing detected
Hi, I have just upgraded osgearth-3.2 to the 3.3 release. It has been compiled and built using cmake without any issues but when I run any of the utils in build/bin I got the following message (and it crashes):
❯ ../build/bin/osgearth_viewer boston.earth ObjectWrapperManager::addWrapper(): 'osg::DummyObject' already exists. ObjectWrapperManager::addWrapper(): 'osgEarth::ClampableNode' already exists.

The code that I developed using the libraries crashes as well... Is it already a known issue? Does it have a quick fix?
I ran "osgearth_version --caps" to provide some helpful (I hope) insights about my setup. Here's the output:

Thank you very much for your help!
Did you do a full clean rebuild and delete any old files you have laying around?
Hi, Thank you for your reply. I have just cleaned and rebuilt everything and I have managed to make osgearth_viewer work again (there were probably some old files inside the system directories that I missed before).
Then I moved to try and rebuild my code. It is built without errors and warnings but when I run it, I get a very long list of messages that end up with a segmentation fault. Here's the output:

These errors are usually due to not having a GL3-enabled version of OpenSceneGraph. (http://docs.osgearth.org/en/latest/faq.html#runtime)
Hi Glenn, thank you for your reply. I have been looking for a possible fix since I opened this issue and yesterday I began suspecting that it was related to GL3. Since then, I have already tried several CMake configurations (I found a few in the OSG forum and on the Internet) to build OpenSceneGraph with support for OpenGL 3+ but none of them work on my laptop (I noticed that I only have a "/usr/include/GLES3/gl3.h" include file in my laptop's filesystem. Should I have a GL3 directory as well?).
Anyway, setting the flag OSG_GL3_AVAILABLE=ON, I can build OSG without errors but when I run osgViewer to view the 'cow.osgt' 3D model, I have an empty OSG blue screen, without any model, and a lot of 'invalid operation' warnings in the terminal... I am copying and pasting just a few lines:
Warning: detected OpenGL error 'invalid operation' at after drawable.compileGLObjects() call in GLObjectsVisitor::apply(osg::Drawable& drawable)
Warning: detected OpenGL error 'invalid operation' at after RenderBin::draw(..)
Warning: detected OpenGL error 'invalid operation' at end of SceneView::draw()

Warning: detected OpenGL error 'invalid enumerant' after applying GLMode 0x4000
Warning: detected OpenGL error 'invalid operation' after applying attribute Material 0x55f76bc588b0
I know that I am going out of scope because it is a OSG-related question but do you have any idea about what I am doing wrong? The NVIDIA drivers that I have installed are from the Ubuntu 20.04 NVIDIA drivers metapackage (Software & Updates, Additional Drivers). Hopefully, they should be complete...
Could it be easier if I use vcpkg to install OSG and osgEarth?
Thank you again!
Brief update
I used the guide you posted here and now I can see a completely black cow and other warnings:
❯ ./osgviewer ../../../OpenSceneGraph-Data/cow.osgt
Warning: TexGen::apply(State&) - not supported.
Warning: Material::apply(State&) - not supported.
Warning: TexGen::apply(State&) - not supported.
Warning: Material::apply(State&) - not supported.
Warning: TexGen::apply(State&) - not supported.
Warning: Material::apply(State&) - not supported.
Warning: TexGen::apply(State&) - not supported.
Short answer is yes: it would be much easier to install everything from vcpkg :)
The "not supported" warnings are because TexGen, Material, et al. are old GL fixed-function pipeline (FFP) mechanisms, and GL3 and osgEarth do not support FFP. (see the OSG_GL_FIXED_FUNCTION_AVAILABLE flag disabled in cmake).
Instead osgEarth relies on shaders (and shader generation). You can run the shader generator on the command line like so:
osgviewer cow.osgt.osgearth_shadergen -l osgearth
You'll still get the TexGen warnings, but at least the cow will look right.
Thank you! I removed all the old files and now I am going to try with vcpkg. I think it will take some time to download and rebuild everything...
Yes, it takes a good while the first time, but after that everything is cached and it's fast :) Good luck.
Something is still missing. I followed these guidelines (The documentation here is focused on Windows, I am building osgEarth for Ubuntu 20.04).
It looks like gdal and openjpeg have been downloaded by vcpkg, but I get an undefined reference error

Any ideas?
Hmm.
Just a guess but this seems like a possible build issue with GDAL; you might try using an older version of GDAL like 3.4.2 (for example; that's what I am using on Windows) and see if it works. Do do this just edit the vcpkg.json file and specify an override, as show here: https://github.com/microsoft/vcpkg/issues/21357#issuecomment-1094153309
Good luck and let me know if that works.
I went from "Wow, vcpkg is so cool!" to "I really hate vcpkg!" just in a couple of days :sweat_smile:... but I will keep trying to make it work and I'll let you know. Thank you! :+1:
Update: I added the override to select the version for GDAL (cmake prints -- Found GDAL 3.4.2), unfortunately, the final outcome is still the same:

Give me a bit of time to reproduce and figure out what it is doing in Linux. This part: cmake -S osgearth-3.3 -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX=~/OSG/osgearth-3.3 -DCMAKE_TOOLCHAIN_FILE=~/gitrepo/vcpkg/scripts/buildsystems/vcpkg.cmake -- Running vcpkg install -- Running vcpkg install - done
Where it is automagically finding and building all the dependencies is not something we have tested. Traditionally we split the two builds, let vcpkg build all the dependencies by using something like vcpkg install osgearth:x64-linux which places all the dependencies in the installed folder. Then clone and cmake osgearth with the buildscript to find all the dependencies from the vcpkg folder. This appears to be doing a manifest local install instead of referencing my pre-built vcpkg libraries and failing where I would bet if you try vcpkg install osgearth:x64-linux , it will succeed.
OK, I get the same

I tried various combinations to try to get this to work, but I think we decided the general issue is shared/dynamic vs static libraries. VCPKG by default builds and tests static and the dynamic is community supported and not tested. Building osgearth:x64-linux-dynamic did not work for me. Building all the dependencies static linking does work in vcpkg but then osgearth is really setup to build with dynamic linking. Even if I set shared libraries to OFF, it seemed to still build dynamic. I couldn't get both sides to build in the same linking style. Going back to what you were doing, you can remove the vcpkg.json file and that will stop the manifest build which is causing other problems as you noticed in gdal. If you clone vcpkg and vcpkg install osgearth:x64-linux, that will build all the dependencies and then you can reference the buildscript in the cmake build to find all the libraries. There is still an issue with resolving fontconfig (optional in openscenegraph) and then a couple more unresolved references trying to build the applications. You can dig deeper into it if you want to go down that path. The osgEarth source is patched to build in vcpkg, so there is some chance that applying the same changes would fix the problems but I did not try it.
The traditional linux build path is still easier using apt-get. It looks like this:
sudo apt-get update -qq
sudo apt-get install libgl-dev
sudo apt-get install -y cmake
sudo apt-get install -y libopenscenegraph-dev
sudo apt-get install -y libgdal-dev
sudo apt-get install -y libgeos-dev
sudo apt-get install -y libsqlite3-dev
sudo apt-get install -y protobuf-compiler libprotobuf-dev
sudo apt-get install -y libpoco-dev

Thank you @gwaldron, @plevy for your help.
In the meantime, I managed to rebuild from scratch (i.e. without vcpkg) the GL3-enabled version of both OSG 3.6.5 and OsgEarth 3.3.0 and I tested them within the software I am developing. It runs, but I will have a lot of work to do to upgrade my code as well and get rid of many warnings and other things that do not work as they should. I found out that I was leaning too much on the old GL fixed-function pipeline (FFP) mechanisms :sweat_smile: and, at the moment, I am not very proficient with modern OpenGL.
Basically, GL_LINE_STRIP geometries are not rendered at all ("Warning: Material::apply(State&) - not supported.") and the colors of imported models change when I move the camera (same warning: "Warning: Material::apply(State&) - not supported."). Appending ".osgearth_shadergen" in the osgDB::readNodeFile function removes the warnings but messes up the colors even more.
So, I think that, for now, I will keep both the GL2 and GL3 versions. I won't give up on GL3, but upgrading my code will take more time (and more study time) than I initially thought.
Thank you again! :+1:
