[Krillin]

With trying to add this bot to our servers this morning, we get the following messages

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!!!

Good luck,
Krillin

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!

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).

[Weasel]

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!

[Whistler]

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]

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".

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.
