I tried bypassing the test-rrd test, allowing the system to create the Makefile, then went ahead to compile and run. Any attempt to display a graph will result in this line in the apache error log: /usr/lib/hpux32/dld.so: Unable to find library 'libz.so'.

When I look at what the librrd.so is referencing

ldd /usr/local/rrdtool/lib/librrd.so|grep libz

    libz.so =>      /usr/local/lib/hpux32/libz.so
    libz.so =>      /usr/local/lib/hpux32/libz.so

and that file exists

ll /usr/local/lib/hpux32/libz.so

-rwxr-xr-x 1 root 1307 275176 Apr 20 2010 /usr/local/lib/hpux32/libz.so

and the LD_LIBRARY_PATH referenced it during the make and compile

set|grep LD

LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib/hpux32:/usr/lib:/usr/local/rrdtool/lib

So I am at a loss to see why it isn't being picked up.

-----Original Message----- Why thinking it is libz? Can you show the error messages after finding rrd?
