RPI4 compilation with Code:Bloks IDE

[HDTV101]

Re-installed RPi4 OS. Followed the raylib instructions to the letter! It seems that the Raylib-3.5.0 must be unzipped into the /tmp directory?

Set up Code Blocks build options to compile and link the shapes_colors_palette.c example.

Compilation and build successful.

Now when I try to run I get an OS error window saying: You must select a host application to "run" a library...

So I changed the build target to GUI application and rebuilt.

Now I get these errors:

This discussion seems a duplicate of a previous discussion. Please, could you post the full compilation line you use?

[HDTV101]

But don't I also need to set the system up differently. you instructions say to install one or the other only.

[raysan5]

Yes, you can only use one or the other, they are completely different configurations. One runs over XWindow (Desktop) and the other over the kernel (DRM). Internally raylib uses completely different implementations and libraries.

I think that default OpenGL driver configuration on RPI should work for Desktop mode.

[HDTV101]

OK it works! Thank you for all your help. As PRi4's are cheap enough I think I'll set another one up to be command line only.

[raysan5]

Nice! Glad to know it finally worked! 👍🙂

bare in mind the console one, you can set up with network shares and SSH, you can then compile / make on the network share and use ssh to run the executable, but bare in mind input via ssh is different, or you could use a second keyboard attached to the console pi (which would probably be less complication than ssh!)

Good luck with your PI / Rayib adventures !
