r1q2 how to compile - linux?

[Tofik]

basing on that source code https://github.com/tastyspleen/r1q2-archive

i was failing at

You will need to create the .depends directories in each of your binaries folders (game, client, r1q2ded, ref_gl) that should correct your error.

  Just noticed my response was too late  As for any other errors make sure you have zlib1g installed.

Still landing in same spot i pass im not into coding

The fatal line is actually a little bit above where your post quotes:

In file included from ../../ref_gl/gl_draw.c:23:0:
../../ref_gl/gl_local.h:27:19: fatal error: GL/gl.h: No such file or directory
 #include <GL/gl.h>

The #include <GL/gl.h> means the build expects a module (the OpenGL module libraries and their headers) to be installed on your Linux and the path to that library to be available to the compiler.

You'll have to search for how to install the OpenGL development libraries for your version of Linux.

P.S. If you are not intending to build the full client and the ref_gl but only want to build the r1q2ded server then all you need to do is 'make r1q2ded' and you are done. The dedicated server binary will be in the r1q2ded directory.

thanks for response, but

im still landing on same spot, don know how to edit path or im supposed to edit every .h file (which can cause more troubles)

ok it makes client

but it has missing viedo drivers where we talked before

os. firstly i thought its good place to make topic, so can moderator move it to thouble shooting ?

Keep to step by step.

Did you check the OpenGL installation by copy-pasting their sample code in that Wiki? If it works then cd into the r1q2 binaries and did make ref_gl complete without errors?

From your post it looks like it worked but your r1q2 client isn’t opening the ref_gl but is opening ref_softx, the software renderer. This is not part of r1q2 but comes with quake2 for Linux. You have me a little confused now.

Did you do ‘make install’ after building r1q2 successfully? I believe this was the next step but check the instructions for r1q2 as I don’t have access right now. R1q2 does assume you have the original Quake2 for Linux previously installed.

No, its landing at same place:

Thats nice to hear and i didnt know about that, and yes since mine "ref_gl" isnt compiling it tries to use ref_softx.

anyway  ref_gl its r1ch R1GL or just opengl?

Good. It means the GL package installation worked.

No, its landing at same place:

make[1]: Leaving directory '/home/lsd/r1q2-archive/binaries/ref_gl'
make: *** [Makefile:17: ref_gl] Error 2

Again, you omitted the critical point of error from your "landing at same place".
Yes, make lands at the same place but not necessarily for the same cause.

anyway  ref_gl its r1ch R1GL or just opengl?

Please read the documentation r1ch provided.
It looks like there is no install and you didn't read the documentation on what to do once you get a successful build.
If there were an install recipe, it will fail if any part of the build failed previously so it's pointless to do it.
I haven't built r1ch's code on Linux for several years, I don't remember all the steps.

The ref_gl code becomes ref_r1gl.dll on Windows, I can only presume that it is ref_gl.so on Linux and it's "r1gl" as stated.

It depends on zlib, libjpeg, libpng so you will need the development libraries for them also.

Missing ANY pieces of the packages on which it depends will "land at same place": make[1] Error 1 or Error 2
you must scroll up to see the actual point of error in order to diagnose the failure. Omitting that error information
from your posts makes it impossible to help you.

Yep. You need the development libs for libjpeg and libpng.

The first error was because you don't have the header for png file format and its stuctures.
The second error was because you don't have the info for jpeg files.

sudo apt-get update
sudo apt-get upgrade

Then use your package manager to install the development libraries for libjpeg and libpng. These are not just the application libs but they are the libs and headers just like you installed for the OpenGL.

Note: you can generally ignore warnings in the compiler output during make, the r1q2 code is getting a bit old and the compilers complain about usages that used to pass without warning but ERRORS are what you want to watch for and fix their causes.

Once you have updates, I recommend you 'make clean' and 'make'. You don't want old *.o files laying around.
