AW: How to debug marble-qt in build folder without sudo make install

[Torsten Rahn]

Hello Cui,
 
you are correct about your investigations.
 
Now the help for further debugging:
 
In order to get more debug messages start Marble with
 
marble-qt --debug-info
 
This will also output things like
 
=== MarbleDirs: ===
Local Path: "/home/tackat/.local/share/marble"
Plugin Local Path: "/home/tackat/.marble/plugins"

Marble Data Path (Run Time) : ""
Marble Data Path (Compile Time): "/usr/local/share/marble/data"

Marble Plugin Path (Run Time) : ""
Marble Plugin Path (Compile Time): "/usr/local/lib/marble/plugins"

System Path: "/usr/local/share/marble/data"
Plugin System Path: "/usr/local/lib/marble/plugins"

... which should help you to see where Marble is looking for its data and 
plugins.
 
Another cue: Starting Marble with
 
marble-qt -h
 
This allows you to adjust data and plugin path at runtime.
Adjusting it at compile-time can be achieved by changing these 
 
MARBLE_DATA_INSTALL_PATH
MARBLE_PLUGIN_INSTALL_PATH
 
in the cmake call.
 
Hope that helps :)
 
Which problem do you want to debug? :-)
 
Best regards
Torsten

Hi Torsten,

Thank you for the quick help!

You are right, I am building and debug marble on Ubuntu 22.04.

I do as your recommended, and added the built library paths:

build/src/lib/marble

build/src/lib/astro

into /etc/ld.so.conf.d/local.conf

Now I do can run ./marble from build folder.

However, it shows a blank Marble window as attached screenshot, also below 
displayed in Terminal window:

--------

$ ./marble-qt

 

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use 
QT_QPA_PLATFORM=wayland to run on Wayland anyway.

 

Map theme file does not exist: ""

 

No plugins loaded. Please check if the plugins were installed in the 
correct path, or if any errors occurred while loading plugins.

 

Falling back to default theme: "earth/srtm/srtm.dgml"

 

Map theme file does not exist: ""

 

Couldn't find a valid DGML map.

I guess it is because marble can’t find data/plugin path (which suppose to 
be installed by sudo make install)? Is there way to let marble also know to 
get such data/plugin from build folder?

 

Thanks in advance!

Hello,
 
thanks for looking into the adventure of compiling marble-qt (which should 
be relatively easy compared to other software).
 
Your problem sounds like a typical one that frequently happens to people 
compiling on Ubuntu/Debian.
As a possible quick fix you might want to start marble-qt on the 
terminal/shell via:
 
LD_LIBRARY_PATH=/usr/local/lib marble-qt
 
In case this works you might want to follow up on this stackoverflow 
question (the common place where coders borrowed their 
knowledge/codesamples from before chatgpt arrived):
 
<https://stackoverflow.com/questions/69061258/permanent-fix-for-export-ld-library-path-usr-local-libld-library-path>
 
Hope this helps :-)
 
BR
Torsten

Hi,

As I want to debug marble-qt and library, but after finish build, by 
default can run marble-qt in build folder as it won’t find library in 
system folder.

Right now I have to run sudo make install all these files, then debug it.

I just wonder is there a way to run marble-qt and let it find library and 
data in the marble/build folder, without have to install them after 
rebuild?

Thanks in advance.
