zlib.sl --> libz.sl

[jcmcdevitt]

Why can't the system find libz.sl? I can see the file and it is in the path:

# echo $SHLIB_PATH
/usr/vsaunix/HP-UX/cmnagent/lib

# ll /usr/vsaunix/HP-UX/cmnagent/lib/libz.sl

You should confirm if your libz.sl is a 64-bit binary because PHP extention zlib.sl
requires 64-bit, not 32-bit.

If your libz.sl is 64-bit, you should add
/usr/vsaunix/HP-UX/cmnagent/lib to SHLIB_PATH defined in apachectl.

Right. That's why shlibs should be put into directories with the HP-UX convention:
lib/hpux32/ and lib/hpux64/.

Thank you. That seems to be the issue. I wish HP would have bundled the libs with the PHP install.

If you can accept to upgrade your HP-UX Apache-based Web
Server, the issue has been resolved yet.

- HP-UX Apache-based Web Server v.2.20 (Apache 2.0.59 base) or later
- HP-UX Apache-based Web Server v.3.0 (Apache 2.2.8 base) or later

You don't have to install some OSS libraries PHP extentions
depend. Because PHP extentions are linked with archive
library/libraries they require respectively. For example,
zlib.sl is linked with libz.a.

Hope this helps you.
