Rocky runs but cannot see any earth.

Question

Rocky runs but cannot see any earth.

Closed this issue 8 days ago · 18 comments

So I just built rocky on my Ubuntu 22.04 using vcpkg. I tried running rocky_demo but only the menu window appears but nothing else. The terminal prints out these line:
[rocky info] PROJ says: proj_create_from_wkt: missing [
[rocky info] PROJ says: proj_create_from_wkt: missing [

What could be the problem?

Great question :)
Please run rocky_demo --version-all and post the output.

Also, I would like to see your Version.h file that was created and installed in the rocky include folder.

You can also try a map with local data, in case there's a networking problem:
rocky_demo --map data/geotiff.map.json

So rocky_demo --version-all gives the output:

Answer 3 · 2024-10-10T14:39:44.000Z

Maybe you need to set your PROJ_DATA environment var to point at the PROJ share dir. If you installed from vcpkg it should be in you vcpkg installed folder, under share/proj

Answer 4 · 2024-10-11T07:59:31.000Z

I already did.
echo $PROJ_DATA
/home/longtt/.VSG/rocky/build/vcpkg_installed/x64-linux/share/proj
I also already downloaded the PROJ-data repo on github to this folder.

Answer 5 · 2024-10-11T15:43:05.000Z

Try pulling the latest rocky, and run it with the log level argument. Maybe this will reveal why PROJ is failing.

rocky_demo --log-level debug

Answer 6 · 2024-10-14T07:54:55.000Z

So I have rebuilt and run like you said and the messages are:

Answer 7 · 2024-10-15T12:39:10.000Z

I'm not able to reproduce this on either Windows or WSL2 Ubuntu. The only course of action I can think of is to set a debugger breakpoint or examine the code and figure out why PROJ is getting an empty string. The function in question is here:
https://github.com/pelicanmapping/rocky/blob/main/src/rocky/SRS.cpp#L129

Answer 8 · 2024-10-29T12:36:03.000Z

Any luck with this?

Answer 9 · 2024-10-31T02:53:51.000Z

So I found that I have another version of proj on my computer, so I deleted it and tried to rebuild. Currently with latest rocky pull I have several error while building which may be related to the version of gcc I am using:

/home/longtt/.VSG/rocky/src/rocky/AzureImageLayer.cpp:111:27: error: ambiguous overload for ‘operator<<’ (operand types are ‘std::basic_ostream<char>’ and ‘const rocky::optional<unsigned int>’)

and

  316 |         registry.on_construct<T>().disconnect<&SystemNode<T>::onConstruct>(*this);

May I ask which version of gcc and g++ are you using for rocky on Ubuntu?

Answer 10 · 2024-10-31T14:17:29.000Z

Thanks.
We develop on Windows with VS 2022, so sometimes the gcc compiler errors lag behind.
On Linux we use Ubuntu 22.04.
I just pushed an update that will hopefully fix your issues.

Can you please post a gdb stack trace?

gdb rocky_demo
(gdb) run
(gdb) bt

By the way, have you tried building and running the apps in vsgExamples ? It would be nice to know if you can run basic VSG stuff before trying to debug Rocky.

Answer 13 · 2024-11-06T08:34:29.000Z

At least vsgmaths, vsgdraw, vsgcameras, vsgbuilder, vsgtext, vsgtexturearray run just fine. Here are the gdb output:

This commit 2c26714 will hopefully solve the Validation Errors you are seeing on startup.
Please test.
No idea if that is the cause of the VSG compilation crash though.

While the validation error was suppressed, I still get the segmentation fault. The gdb trace remains the same:

I'm afraid I am at a loss on this one...
If you are handy with gdb (I am not) perhaps you can query some of the member variables in vsg::Geometry to see if something's null or uninitialized. Beyond that I can only suggest posting something on VSG Discussions to see if anyone has any tips.
