Linux Arch/Fedora:
libGL.so file missing I tried changing S_init(), the error remained the same

@ AZJIO
i know nothing about linux
concerning import, I took it from a pjay code

Don't you blame me

I haven't used Linux for any PB development so far (although it's on my radar), so I know very little about the correct way to setup the GL environment - if you've seen it in my code then it has come from somewhere else.

Re: libGL.so file missing

I found the path in Void and Arch to be "/usr/lib/libGL.so".

Can't speak for Fedora as it's not a Linux I use.

The image path separators need changing from "\" to "/" as well.

I have lib64 as a link

In my Arch install, it finds libGL.so in both /usr/lib and /usr/lib64. I don't have an issue with it not being found.
I take it the lib that the links point to does exist somewhere? I followed the trail to something called libGL.so.1.7.0.

In the terminal mine only shows up in the /usr/lib/ folder.
$ whereis libGL.so.1.7.0
libGL.so.1.7.0: /usr/lib/libGL.so.1.7.0

I'm using a tweaked version of Archbang which is pretty minimal so I kind of expect things not to work.
It seems a bit flaky. Sometimes I get invalid memory access errors, sometimes gtk_widget errors.
Removing #PB_Window_ScreenCentered from line 730 seems to help for some reason?
Other than that it works OK except the text on the screen is upside down!

Since there is a search path in linux, ist'n it enough to use

Code: Select all

ImportC "libGL.so"

Not on my Archbang install.

/usr/bin/ld: cannot find libGL.so: No such file or directory
collect2: error: ld returned 1 exit status

It allows us to use opengl shaders (GLSL)? I'm interested, now I have to find some time to look into it.

Thank you!

Looks very interesting, good work !

It is all dark for me; in the first frame(s) there's something to see for a very short time but it resembles artifacts from the displayed colors.

Here's what it says for me
I also had trouble with some other openGL examples on Windows 10 but I forgot about it.

in linux, texture file names are in a different case

Remove the word compatibility from the shaders. In GLSL 1.30 it only supported the version number, no profile.

Well, I'm very sorry but the change didn't make it work - even tho there's one or two error messages less

(I have no clue what the profile etc. means I am totally "new" to OpenGL)

@benubi

can you try again, I made the corrections
