Quake on ubuntu

[Cobalt]

Hey , I always wondered , why when using Linux or derivitaves, you have to go through all this command line intricacy just to get a program to work? Is there no such thing as a Linux installer? I know this is not a Linux OS forum , but if someone could explain this, I would appreciate it. Kudos for Quaking with Linux.

[spooker]

linux installers install the basics, but for each program there are things called dependencies.....files the program depends on to run but doesn't include. they're kinda like DLL files. most programs aren't distributed with all the files they need to work, so you have to find them elsewhere, the assumption being that if you use linux, you know how to do this

Sure there is , u have a add/remove programs in ubuntu.
1 click to install a program.

Its just when u wanne tryout older programs or games from windows that u need the terminal to get them going.

But for that u can also use a program called wine ,this program can easy run almost any windows program or games under linux,
U can even run glpro for quake using wine No terminal needed then

I had 64bit ubuntu installed but had to install win7, Ubuntu ftw, though its nice and fast! I still need to port Qrack to linux or atleast get it to compile under linux, if anyone has a makefile i could borrow??

Qudos made some fantastic SDL ports, so here you go http://qudos.quakedev.com/linux/quak....1-src.tar.bz2

(He seem to also have added/changed some other things, so it is not a straight-forward diff to do.)

[Mindf!3ldzX]

not quite off topic.....
Have you ever pondered why some people would choose to take a vacation to hell,and then wonder why the ice cream has melted?

[Stalker]

Hey stalk try this at your terminal u will need to add your password again :

sudo echo "glquake_glx 0 0 direct" > /proc/asound/card0/pcm0p/oss



then try quake again.
type:

cd "/usr/local/games/quake1"

then type:
./glquake_glx


Let me know if this works...

"Hej" Pol..

I get a permission denied.

[email protected]:~$ sudo echo "glquake_glx 0 0 direct" > /proc/asound/card0/pcm0p/oss bash: /proc/asound/card0/pcm0p/oss: Permission denied

[MH]

Aaaah, brings back happy memories of the times people used to bug me to do a Linux build of my engine. "It's really easy!" they used to say.

"Hej" Pol..

I get a permission denied.

[email protected]:~$ sudo echo "glquake_glx 0 0 direct" > /proc/asound/card0/pcm0p/oss bash: /proc/asound/card0/pcm0p/oss: Permission denied

Ok...had to (ofcourse) enter root
sudo -i
[email protected] sudo echo "glquake_glx 0 0 direct" > /proc/asound/card0/pcm0p/oss

Game on and sound on...and it looks awfull compared to qrack...
so next project is make qrack running

Thx for all the help in here...

Quore - about

[golden_boy]

You should normally not have to do any of this /usr/local shit.

I have this:

/home/user/quake

/home/user/quake/fitzsdl (and a couple other engines)
/home/user/quake/id1/pak0.pak (etc)

To play quake, I cd into my quake folder and do ./fitzsdl

Done, no usr/local involved. Installing into /usr is only necessary if you want multiple users to have access to the game data (global installation). Package managers usually do this, but it's not really necessary.

You can just download and unzip into your quake folder, like you do under windows. Not all engines might run under 64 bit, though. FTE does:

Index of /moodles/linux_64bit

You may have to make the engine executable by doing chmod +x filename. These things are basic Linux knowledge, though. The Linux Gamers FAQ tells you these things, if I remember correctly.

Linux Gamers' FAQ

Linux Quake HOWTO:

Linux Quake HOWTO

An operating system is one of the things that really get easier if you read documentation.

Quore - about

No, no and NO again. Quore is a mod/engine mixture. It is not Quake you are playing but Quore, a Quake mod.
