Your ldd returned one path to zlib. I suppose this means that in your environment, the library path you've set in the compile flags, "-L/usr/local/rrdtool/lib", somehow expands to -L/usr/local/lib:/usr/local/lib/hpux32:/usr/lib:/usr/local/rrdtool/lib (maybe not in that order).

I'm afraid I can't be of much help here, I'm sure others will have an answer though.

Thanks for weighing in, Tim.

by putting an echo statement in the build/Makefile.test-rrd we can see what is actually being done during the test that fails during the configure.server step

On my system, that test-link function @$(CC) $(CFLAGS) $(RRDDEF) $(RRDLIB) -o test-rrd test-rrd.o -lrrd $(PNGLIB)

expands to look like this: gcc -g -O -D_REENTRANT -DHPUX -L/usr/local/rrdtool/lib -o test-rrd test-rrd.o -lrrd

If I run that compile manually, this is what I get:

gcc -g -O -D_REENTRANT -DHPUX -L/usr/local/rrdtool/lib -o test-rrd test-rrd.o -lrrd

ld: Can't find dependent library "libz.so"

I have installed 2 versions of zlib for HPUX. The first was the version called out in the RRD documentation (zlib-1.2.3) and when that didn't work, I removed it and installed a more current version (zlib-1.2.5). Changing versions didn't change the error, however.

I'm not familiar with HPUX, but do you have something like truss or strace available so you can see what's going on in startup? If /usr/local/lib/hpux32/libz.so is good then maybe there is some silent version error that can be seen (ie rrdtool expects v1234 and yours is v3421). Really just shot's in the dark....
