Compiling RCBot2 Options

[Cheeseh]

1. Use Visual Studio 2005/2008 (windows)

2. Use a tool such as Ankhsvn or TortoiseSVN for Visual Studio 2005/2008 (windows)
http://ankhsvn.open.collab.net/
http://tortoisesvn.net/

3. Get the appropriate HL2 SDK, from https://github.com/alliedmodders/hl2sdk/ this has updated SDK code
(TF2 SDK https://github.com/alliedmodders/hl2sdk/tree/tf2 )
(DODS https://github.com/alliedmodders/hl2sdk/tree/dods )
(HL 2 DM https://github.com/alliedmodders/hl2sdk/tree/hl2dm)

4. Get the code from sourceforge SVN by opening an SVN project in VS Studio (using AnkhSVN)
https://sourceforge.net/scm/?type=svn&group_id=248612
download the rcbot2 source: using this command svn checkout svn://svn.code.sf.net/p/rcbot2/code/ rcbot2-code
or this server checkout svn://svn.code.sf.net/p/rcbot2/code/

Make sure the project is in the HL2 SDK folder/utils/rcbot2

(Also if you wish to change any code for others to see, make a sourceforge.net username and ask me to add you to the list of coders.)

5. Mar 2013 - note that the latest releases hook to the engine to work properly. This solves many problems that the past rcbot had, but it may create problems in the future, for example TF2 updates may change the engine. For that reasons, if the bot crashes, keep up to date with the website at:
http://www.sourcemodplugins.org/vtableoffsets
and keep the rcbot_runplayer_cmd updated to the latest PlayerRunCommand offset number for windows (the linux offset is added automatically in the bot if the windows offset is correct) .
At this time of speaking, the offset is 418 for tf2 and 417 for DOD:s
Linux offsets are shifted by 1

6. Get coding!

Linux instructions + Makefile are here:

Well I guess it doesn't really matter since I can use sourcemod to change names. But it is really strange that they started to work randomly.

The only thing I did differently was that I gave up, and left the server alone. The next day I added my steamid to accessinfo.ini, rebooted the server, and then it started to work.

Maybe I could provide you with a Linux VM so you could make sure rcbot works on Linux? It is really much nicer than running on Windows. It is really easy to add libraries to it and when the server crashes, you can get debug symbols. You also won't have to restart your tf2 client.

Also have you thought about moving the project to github?

It could be something to do with the server hibernating when there are no human players that join. You might be able to disable hibernating, I'm uncertain about dedicated servers as I never use them, but I've heard similar cases. check http://rcbot.bots-united.com/forums/index.php?showtopic=1727

I haven't thought about gihub, but if it's easier for linux developers to have a look at and edit the code I'd consider it eventually.

could you please help me. I've spent many hours trying to get this to compile and i'm stuck at this:

perhaps try adding -m32 in the gcc command line

got everything forced to m32 but i had issues with my makefile not actually making the thing at the end

i have no idea what to do with these. please help me

you don't need to do anything with them specifically. what's the error?

something was wrong with my makefile its fixed now.

CODE

../utils/RCBot2_meta/bot_main.cpp: At global scope:
../utils/RCBot2_meta/bot_main.cpp:317:1: error: ‘CRCBotPlugin’ does not name a type
CRCBotPlugin g_RCBOTServerPlugin;

i've tried a few things to get past this error, but i haven't been able to fix it yet.

you're using the meta build -- delete bot_main.cpp from the project

you're using the meta build -- delete bot_main.cpp from the project

It's compiling now however i have this issue when loading it.

Failed to load plugin HPB_bot2_i486.so (/home/steam/tf2/tf/HPB_bot2_i486.so: undefined symbol: gameclients

how should i go about solving this?

here is my makefile: http://pastebin.com/YEdff5wF
thank you

is bot_plugin_meta.cpp being compiled? This is the most important cpp for metamod version -- also remember it can only be loaded through metamod
