Can't find path for shared library libexslt.sl.7

Masaki Birchmier — Thu, 28 Oct 2004 10:35:14 GMT

Hello all,
I have a newly installed 11.11 system where I am trying to get the domxml PGP extension to work on Apache.

The php.log entry is...
PHP Warning: Unknown(): Unable to load dynamic library '/opt/hpws/apache/php/lib/php/extensions/domxml.sl' - Can't find path for shared library: libexslt.sl.7 in Unknown on line0

I have installed libxml2 and libxslt from the Porting Center. They installed to /usr/local/lib although there is no instance of libexslt.sl.7, only libexslt.a, libexslt.la and libexslt.sl

I have also included /usr/local/lib in LD_LIBRARY_PATH & SHLIB_PATH for the user that apache runs as (in my case user www).

I have also tried creating a link in the extensions directory
libexslt.sl.7 -> /usr/local/lib/libexslt.sl
but it had no effect.

The domxml extension worked out of the box with the 11.00 apache installation, but the 11.11 version does not work.
Please help with any suggestions.

Thanks,
Masaki

What are the perms on /usr/local/lib/libexslt.sl?? Atleast for everybosy. Also as creating the link has not helped, why not copy it in extension dir???

Try it and post.

The permission on libexslt.sl is 555 root:sys
Tried copying to the extensions directory, and restarted apache. Same results.

After copying the file, is error message same as that of first error?

State your apache version number. Is it the hpws kit 2.0.10?

That may be a factor.

What is the source on PGP?

For domxml.sl SHLIB_PATH is disabled. Let us try to enable and check.
chatr +s enable domxml.sl. Now restart apache and check.

can you post the output of "what /usr/lib/dld.sl"?

this may be a known issue which is resolved in the latest linker/loader patches PHSS_30967(11.00) / PHSS_30968 (11.11).

Thanks for your suggestions,
the chatr +s command did not work properly until I installed PHSS_30968.
SHLIB_PATH is now enabled for domxml.sl

Restarted apache, but still getting same php.log error "can't find path for shared library:libexslt.sl.7 in unknown on line 0"

Can someone explain the relationship between libexslt.sl.7 and libexslt.sl ?
I know that "7" represents a major revision level, but I'm not sure how the linker resolves libexslt.sl.7 to libexslt.sl (or does it)?

Figured it out!
ran the command
"odump -sllibload domxml.sl"
and it errored out. So I suspected domxml.sl might be corrupted so I compared domxml.sl on another 11.11 system and discovered the size was quite different. Copied domxml.sl from the other sytem, and all is good now.

Good debug tools for library isses: ldd, chatr, odump, elfdump

"odump -verifyall" is helpful in checking whether a PA32 binary is corrupt.

I have exactly the same problem, but no second HPUX 11.23 system to get a non-corrupted domxml.sl. Could anybody please tell me where to get it (System CD?) or just mail it to me...
