Hi

LD_LIBRARY_PATH env variable should contain two paths:

1. a path where libraries of RRDTool application are located

this is what I've got in my system:

vaja ant # ls /usr/lib/*rrd*
/usr/lib/librrd.a   /usr/lib/librrd.so.2          
/usr/lib/librrdPlugin.a   /usr/lib/librrd_th.la    
/usr/lib/librrd_th.so.2.0.1
/usr/lib/librrd.la  /usr/lib/librrd.so.2.0.4      
/usr/lib/librrdPlugin.so  /usr/lib/librrd_th.so
/usr/lib/librrd.so  /usr/lib/librrdPlugin-3.0.so  
/usr/lib/librrd_th.a      /usr/lib/librrd_th.so.2


Ant script suggests this path using 'rrdtool_path' property from 
ant/const.properties ('rrdtool_path' is a base path of RRDTool 
application. In my system this application is in /usr/bin/ directory so 
base path is /usr. 'rrdtool_path' can be set up manually or during 
automatic configuration run by 'ant configure-rrdma'.)


2. a path where native library of rrdjtool has been created

this is what I've got in my system:

vaja ant # ls /root/Download/dev/sonar-head-20060224/sonar/rrdjtool/build
CVS  libjrrd.so  rrdjtool.jar


-----


So in my system LD_LIBRARY_PATH contains:

/usr/lib:/root/Download/dev/sonar-head-20060224/sonar/rrdjtool/build
