Which version of qt is it using? If you'd like to share your compile command, I'll take a look, see if we can figure it out?

Just curious if anyone has gotten Stellarium running yet.

Hi

I managed to figure out how to compile Stellarium (0.11.4) on the RasPi and found a way around the compile error messages ericskiff mentioned a few posts ago.
The key lies in the files /usr/include/GL/glext.h and /opt/vc/include/GLES2/gl2.h.

Before you all start cheering, Stellarium still fails to work.
When I run the executable I get the error message that OpenGL is not supported.

Here's the logfile it generates:

Also starting stellarium with the --safe-mode switch or adding use_glshaders=false in the config file doesn't help.
Stellarium is compiled using cmake -DOPENGL_MODE=ES2

Anyone out there who has an idea what could be the cause?

Hmmm. Stellarium worked for me with those compile flags set, and some removed stuff to do with architecture. But was very slow. And that was on a proto board. THis was also before hard float.

Ah, are you running from within X? I think the binding from X to accelerated GLES isn't there yet? Can you run from outside a desktop?

I am running from within X (standard LXDE).
When I start from the command prompt (X not started) I get the message that stellarium couldn't connect to a X Server.

It's so long since I tried this, I cannot remember what I did. I've checked my notes but nothing relevant.

How do you compile this on the pi. 'cmake' is a directory, not a command ?
Perhaps I,ve downloaded the wrong package........

Texy

install cmake with: sudo apt-get install cmake

There's some more stuff you need to compile Stellarium and some edits/hacks in files here and there.
If you followed this thread a bit, you might understand there are some problems compiling it out-of-the-box (in other words, it fails to compile).
Before I can write down a proper tutorial how to install Stellarium on your Pi, I need to get my head around that OpenGL problem.
I think I'm quite close to solve the problem.

@jamesh : think hard!

OK. Look forward to the tut

...so how did you fix this?
I,m getting this error at 45% :
