Hi, I've already use the TPTP and Agent Controller on my Linux without
problems.
But now I've installed the BEA jvm and in the starting of the agent this
error message in showed:
Could not find the pthread library. Are your running a supported Linux
Distribution?

Any suggest?

Thanks!

What exactly is reporting that it can't find the pthread library?

The linux dynamic linker usually finds the pthread library using the
LD_LIBRARY_PATH environment variable... in addition to various
default settings such as /usr/lib and /usr/lib. (see man ld.so)

What version of linux are you running on? Can you find /usr/lib/pthread.so?

Try doing an "ldd" on the executable reporting the error? Let me know what
version of pthread it is referencing.

Regards,

Kevin

Hi Kevin,
with ldd RAServer command I see this:

libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x40695000)

and it's the same result with ldd RAServer command using HotSpot jvm(with
this kind of jvm Agent Controller has no problems to running).
My LD_LIBRARY_PATH is:
LD_LIBRARY_PATH=/usr/lib:/lib:/lib/tls:/lib/i686:/usr/includ e:/usr/include/nptl:
/usr/include/nptl/bits/:/usr/jrockit5.0/jre/lib/i386/native_ thread:/usr/AgentCon

sr/java/jdk1.5.0_05/jre/lib/i386:/usr/java/jdk1.5.0_05/jre/l ib/i386/server

I have Mandrake version with:
Linux 2.6.8.1-12mdk Machine i686

Thanks for help,

Another element.

In the README of bea jvm ther is this note:

LD_ASSUME_KERNEL on Linux

When using BEA JRockit(R) JDK 5.0 Update 3 (RR25.2.0-28) @JROCKIT_KIT@ on
Linux, you should first
make sure that the environment variable 'LD_ASSUME_KERNEL' is *not*
defined. BEA JRockit(R) JDK 5.0 Update 3 (RR25.2.0-28) @JROCKIT_KIT@
supports the NPTL threading
library. However, if 'LD_ASSUME_KERNEL' is defined, it will direct
the runtime linker to use the older and slower LinuxThreads threading
library instead, for no benefit.

Anyway with the command: echo $LD_ASSUME_KERNEL
the result is empty

Since you are using Mandrake with a 2.6 kernel I don't think
the problem is realted to LD_ASSUME_KERNEL... It is
my understanding that this was used for the later generations of the 2.4
kernel to support both nptl and linux threads. I don't think this applies
for
2.6. (but correct me if I am wrong on this)

But in this case based on your ldd you are using nptl, notice the tls in the
paths of your executables and since you don't have LD_ASSUME_KERNEL defined
then it doesn't come into play)

Both your ldd and LD__LIBRARY_PATH look good.

It's still unclear to me based on your description what is producing the
error
message about the pthread library... Can your track this down?

Hope this helps!

Thanks

Kevin

Hi Kevin,
What do you intend with "can your track it down?"
Anyway according to me the most important aspect is that the Agent
Controller doesn't work only with BEA JVM (in fact I've used successful
RAServer with Hot Spot JVM), but if I use this JVM without Agent
Controller I haven't problems.
Have you an email address? It'd be a faster way of communication: i need
to solve this trouble fastly. My address is: clelia.cangiano@gmail.com
Thanks a lot for you graceful helps. Have a nice day!

It was unclear to me based on your previous messages what executable
was reporting that it could not find the pthread library. All I meant was
could you tell if the JVM was reporting the error or the Agent Controller
was.

Thanks

Kevin

Hi,
The error message comes from Agent Controller.
Have a nice day!
