Interesting, don't you think? We tried to use HPB_BOT 4 on linux dedicated server.

We do not want to know what the problem is or what the solution is. We are tired of the dead and abandoned bots-united now bots-divided. Nothing here works. Trust us, we've tried!!! :censored:

Good luck,
Krillin

Re: HPB_BOT badf load, (not loading)
 
Damn that sux! I'm trying to do the same thing right now, and having the same issues. I had planned to convert all my Windows-based HLDS servers to Linux. But, that would normally include a small compliment of bots on Half-Life and TFC servers. Now I guess I'm stuck with Windows! :no:

Here's my HLDS output ...

I particular, I noticed the error "undefined symbol: sqrt". Maybe a reference to some compile dependency that was missed or something?

I once got HPBots to work, but that was long ago.
Now I just use RCBots.

Try to install these packages for your distribution and retry. Please advise if this helped as it fixed mine.

compat-libstdc++-33
compat-libstdc++-296

also these if that dont work
compat-gcc-34
compat-gcc-34-c++

That should get things moving.

if using fedora the Yum command is


yum -y install compat-libstdc++-33 compat-libstdc++-296
yum -y install compat-gcc-34 compat-gcc-34-c++

Just thought I would update (late, I know). I did try that. Still got that "undefined symbol: sqrt" error.

I did switch to JK_Botti on my Half-Life server. Now I'm looking for a (working) bot for DMC (on Linux). No luck so far (on the "working" part).

Re: HPB_BOT badf load, (not loading)
 
I did some digging around the Internet(s), and it seems like the "undefined symbol: sqrt" error (seen at run-time) is the result of a missing command-line option - that should have been used during the most recent compile.

From that I've been able to gather, this issue is seen quite often - when people are trying to compile their own copies of Apache or other open-source software. Apparently, the missing command-line option is "-ml", which instructs the compiler to link to the required math library (which contains the "sqrt" function, among other things).

I have a Linux machine up, but have no experience with compiling anything on it under GCC, etc. - much less Valve-related stuff. Not sure if I even have all the right components installed to do a successful compile (for example, do I need the Valve SDK installed on the Linux box?).

Here's a couple of examples citing the missing "-ml" option:

Why is it alway said that "fabs" and "sqrt" are undefined symbol?

math.h not working? o.0

From what I gather, no source-code changes should be required, just a re-compile (and/or possibly an updated "make" file that controls the compile).

If anybody can re-compile this bot (with the required command-line option), or show me how to do it, it would be greatly appreciated!

Re: HPB_BOT badf load, (not loading)
 
it should be -lm rather than -ml :)

or maybe try adding this before the command which launches the server:
LD_PRELOAD=/usr/lib/libm.so.6

The Storm 03-03-2011 12:32
Re: HPB_BOT badf load, (not loading)
 
Very strange, I though that when you compile shared library all the dependencies must be provided to the linker else you will get an error...

You're absolutely right. I typo'd them (reversed them).
It should be "-lm". :sailor:

I'll give that PRELOAD command a try.

Unfortunately, that didn't help.
Still getting the same errors.

I tried it two different ways:
  • LD_PRELOAD=/usr/lib/libm.so.6
  • LD_PRELOAD=/usr/lib/libm.so
Neither worked. :(

Weasel 05-03-2011 08:09
Re: HPB_BOT badf load, (not loading)
 
! RESOLVED !

Based on what Whistler posted, I tried the LD_PRELOAD environment variable again, but this time "exported" it. I put that option in my script that launches HLServer, right before the "hlds_run" command, like this:

Quote:
cd /data/games/hlserver
export LD_PRELOAD=/usr/lib/libm.so
./hlds_run -secure -game dmc +port 28019 -sport 28119
Now HPB_Bot loads-up fine on my DMC server , and peacefully coexists with my other mods (AMX-Mod-X, etc.).

Thanks Whistler!

you'll get an error when compiling an application but not a static library (.a) or shared library (.so) :)

The Storm 06-03-2011 14:26
Re: HPB_BOT badf load, (not loading)
 
Yeah for static library is clear why, there is no even a linker operation there, but for shared I don't see a reason for not doing it... However these questions perhaps are for the creators of GCC. :)

Whistler 09-03-2011 04:12
Re: HPB_BOT badf load, (not loading)
 
that way it's easier to reference symbols from the main executable which linked the library or other shared libraries.

twitch 26-03-2011 17:54
Re: HPB_BOT badf load, (not loading)
 
is it possible to recompile the .so that it will work without having to mess with anything else? If so, can someone post a link for that new compiled hpb bot .so file?
