Angband and the Borg on Linux

Hello,

I've been a big fan of Angband since I was a kid, and it's nice to see it getting some attention again. I'm also quite proud of myself, because I've managed to compile it from the source on my Linux box.

However, I'm wanting to compile it with the Borg. Is it even possible to compile in the APWborg for linux?

Once I start to make the files I start running into problems...

Code:
        CC     borg1.c             
        CC     borg2.c             
        CC     borg3.c             
borg3.c: In function ‘borg_read_unknown’:
borg3.c:3348: warning: unused variable ‘ag’
borg3.c: In function ‘borg_read_scroll’:
borg3.c:3489: warning: unused variable ‘ag’
borg3.c: In function ‘borg_spell_okay’:
borg3.c:4119: warning: unused variable ‘ag’
borg3.c: In function ‘borg_prayer_okay’:
borg3.c:4307: warning: unused variable ‘ag’
and then it ends like this...

Code:
        CC     z-virt.c            
birth.o: In function `player_birth':
/home/djp/angband-3.0.9b/src/birth.c:1758: undefined reference to `saver_creates'
birth.o: In function `player_birth_aux':
/home/djp/angband-3.0.9b/src/birth.c:1691: undefined reference to `saver_creates'
birth.o: In function `player_birth_aux_3':
/home/djp/angband-3.0.9b/src/birth.c:1543: undefined reference to `saver_creates'
/home/djp/angband-3.0.9b/src/birth.c:1590: undefined reference to `saver_creates'
util.o: In function `get_name':
/home/djp/angband-3.0.9b/src/util.c:2888: undefined reference to `saver_creates'
collect2: ld returned 1 exit status
make[2]: *** [angband] Error 1
make[1]: *** [build] Error 2
make: *** [build] Error 2
Am I trying to do something thats impossible or am I doing it wrong?

I get the same error. Since the only main-*.c modified by the borg code is main-win.c, I would suspect the borg is for windows only.

The variable 'saver_creates' exists so that the game knows if it has to create a new character automatically (when running the borg through the screensaver).

I did not spend too much time on this, so there is no guaranty, but apparently, in externs.h, changing the following lines :


Code:
extern bool saver_creates; /* apw  */
extern char screensaver_inkey_hack_buffer[1024]; /* apw */
extern int screensaver_inkey_hack_size;
into

Code:
bool saver_creates; /* apw */
char screensaver_inkey_hack_buffer[1024]; /* apw */
int screensaver_inkey_hack_size;
Obviously, this is a bad hack, and you should not mess with the option to automatically recreate a character after death, as this will probably not work.

Also, but this probably comes from my inexperience with installing angband, the game was looking for borg.txt (lower case) in ~/.angband/Angband. You might want to add the following lines in borg9.c, around line 4725 (after the "if(!fp) part) :

Code:
        msg_print("Looking for borg.txt in");
        msg_print( buf );
When testing, my character died from starvation at clvl 6, not too sure if that is ok or not.
Edit: Ok, my current char is clvl 26 and going, so this seems to run as expected, after all.

Hope that helps.

No, it's just developed on Windows and APW has no means of testing on other systems.

Try instead just appending "bool saver_creates;" to the end of variable.c. Works like a dream!

BTW, Unix people;

A version of 3.0.9b + APWBorg + fixes is available using "git". Install the git and git-core packages for your flavour of Unix and run:
Code:
$ git clone git://repo.or.cz/angband/borg.git
Like magic, you'll have working copy. I've just got interested in the borg, which is probably a terrible terrible thing for actually keeping the game maintained, but http://repo.or.cz/w/angband/borg/takk.git is the page with the latest changes to my own branch of APW's borg. Right now it's mainly code cleanup, but I want to make the borg generally a little more aggressive in its playstyle.

You might be interested in being able to run it in xscreensaver, then. I've mailed some stuff to your rephial address.

You are obviously evil incarnate. Not only for giving me something else borg-related to hack on, but also for finding a good reason to keep the X11 port..

Takkaria's git link above was very useful to me. I got the source and am now running angband on linux. But I'm not able to run the borg.

I've followed the steps outlined in borgread.txt (it seems like 2 & 3 were not needed with the git link) but I can't seem to start the borg.

The "angband" command starts the game, but ctrl-z just suspends the game, either when I execute the command on game start or when I have a character loaded.

What am I missing? How do I start the borg?

Thanks!

In that case, try literally '^' followed by 'Z'. Your problem is that you're running in a terminal, and in a terminal ^Z means "suspend". Luckily if you press ^ then Angband lets you press another key afterward and treats it like you'd pressed control and the second key at the same time.
