Hello.
I have a problem with installing yjp-3.2

Don't working configuration:
1. Linux 2.4.27
2. YourKit Java Profiler 3.2 #451
3. Java version
$java -version
java version "1.4.2_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode)

4. Added <YJP Home>/bin/linux to the LD_LIBRARY_PATH
$/sbin/ldconfig
5. Test
$java -Xrunyjpagent:help
Error occurred during initialization of VM
Could not find -Xrun library: libyjpagent.so

Working configuration
1. Linux 2.4.27
2. YourKit Java Profiler 3.2 #451
3. Java version
$java -version
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode, sharing)
4. Added <YJP Home>/bin/linux to the LD_LIBRARY_PATH
$/sbin/ldconfig
5. Test
$java -Xrunyjpagent:help
YourKit Java Profiler 3.2 #451 agent usage: -Xrunyjpagent[:help]|[:<option>, ...]

Question:
How to run yjp under java version 1.4.x ?

1. Perhaps I'm wrong but ldconfig just rebuild information about libraries which are specified in ld.conf file. So there is no need to run ldconfig at all.

2. What is the output of "ldd libyjpagent.so"?

Yes, but I'm specified path in ld.conf

,

2. What is the output of "ldd libyjpagent.so"?

#ldd /opt/yjp/bin/linux/libyjpagent.so
libltdl.so.3 => not found
libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x00158000)
libc.so.6 => /lib/libc.so.6 (0x0020c000)
libm.so.6 => /lib/libm.so.6 (0x00319000)

/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

but,
#ldd /opt/yjp-eap/bin/linux/libyjpagent.so
libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x0017d000)
libm.so.6 => /lib/libm.so.6 (0x00230000)

/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

#apt-cache search libltdl
libltdl - dlopen wrapper for GNU libtool

#apt-get install libltdl
#java -Xrunyjpagent:help

It's worked now

. Thnx

Yes, you are right, ltdl is not needed anymore in the 4.0 EAP version. The corresponding change was not (and will not) be back ported to 3.x.
