know what I'm doing. I just try things, figure out why they didn't work, fix
the problem, and repeat until everything works. I suggest you learn to do
this approach too. You can get pretty far with it.
Nice!
> First we need a copy of the source code. We will use git to make a clone of
the repository on our machine.
$ sudo apt install git
$ cd path/to/somewhere
$ git clone https://github.com/PlayOnLinux/POL-POM-4
This I understand.

Aha, so "bin"-folder are what to look for when building?
> After we build the program, binaries should appear here.
Well aren't there already something there? "check_dd_amd64.bz2
check_dd_x86.bz2"?

build the program. Let's try using make now.
Aha :)
> We get an error:
./src/check_direct_rendering.c:33:19: fatal error: GL/gl.h: No such file or
directory
Well I got something slightly different:
gcc -O2 ./src/check_direct_rendering.c -o ./bin/playonlinux-check_dd -lGL
-lX11
make: gcc: Command not found
Makefile:47: recipe for target 'build' failed
make: *** [build] Error 127
But I searx'd "make: gcc: Command not found". Someone suggested to install
gcc, so I did.
Now $ make gives me:
gcc -O2 ./src/check_direct_rendering.c -o ./bin/playonlinux-check_dd -lGL
-lX11
./src/check_direct_rendering.c:31:22: fatal error: X11/Xlib.h: No such file
or directory
compilation terminated.
Makefile:47: recipe for target 'build' failed
make: *** [build] Error 1
Which still isn't quite like the error message you get. But very close. The
main thing here seems be this: "fatal error: X11/Xlib.h: No such file or
directory", but that tells me nothing. Now I am lost. Stranded on an island.
But anyway, let's suppose I got the same error message as you up to this
point:
I still can't fathom how you from this message:
"./src/check_direct_rendering.c:33:19: fatal error: GL/gl.h: No such file or
directory"
are like: "Oh yeah totally. Looks like the development libraries for opengl
are required and I don't have them installed. Let's fix that and try again.
$ sudo apt install libgl1-mesa-dev" :P
Haha, but anyway. Don't interpret this as a token of ungratefulness. I really
do appreciate the effort you put in this walkthrough for me. But because of
factors I suppose neither you or me could've known about, it doesn't "walk me
all the way through".
But maybe ... maybe perhaps you are able to solve the error I got?
If not: that's okay! :) Thank you anyway
