Unable to load shared library gettext in php

[Harichand M V]

I am using a HP-UX with apache version 2.0.58
and with php 5.2

I compiled and installed the gettext extension

On apache startup I get the warning
PHP Warning: PHP Startup: Unable to load dynamic library '/opt/hpws/apache/php/
lib/php/extensions/gettext.sl' - '/opt/hpws/apache/php/lib/php/extensions/gettex
t.sl' is not a valid load module: Bad magic number in Unknown on line 0

Please help

Shalom,

Check that the files it is complaining about actually exist and have the correct file time.

file filename.

If possible compare size and type to a system that is working.

The complaint seems to be either the library is inaccessible or invalid, I lean toward invalde based on the meaningful, magical error message.

SEP

I have checked with the existence of the file gettext.sl
and the php.ini file.
I actually created the gettext.sl by following commands in the php-5.2.5/ext/gettext directory.

I first copied config.sub,config.guess and ltmain.sh from /usr/local/share/libtool/config directory to gettext source directory.

# phpize
# ./configure --enable-gettext --with-php-config=/opt/hpws/apache/php/bin/php-config
# make
# make install
# cd /opt/hpws/apache/php/lib/php/extensions
# mv no-debug-zts-20060613/gettext.so gettext.sl
# apachectl restart

When I checked the error log of apache I got the above mensioned magic number error message

[Harichand M V]

I checked shared libraries with following commands

# file libphp5.so
ELF-64 IA-64
# file gettext.sl
ELF-32 IA-64

I think the mixing up of 32bit and 64bit libraries the root cause of problem.

Can any body help with how i can build 64 bit
libraries?

Thanks in advance.

>I have checked with the existence of the file gettext.sl

That's useless. You also need to check what type of file it is. Use a linker tool:
$ chatr gettext.sl

You could have PA vs IPF conflicts. Or +DD32 vs +DD64. And it must be a shared lib.

>SEP: I lean toward invalid based on the meaningful, magical error message.

Exactly.

Can libphp5.so load the shared library gettext.sl??

[Dennis Handly]

# chatr gettext.sl
32-bit ELF shared library
#chatr libphp5.so
64-bit ELF shared library

>Can libphp5.so load the shared library gettext.sl??

No. An application can either be 32 bit or 64 bit.

>I compiled and installed the gettext extension

You will have to port? and compile this to 64 bit.

[Harichand M V]

How can I compile the gettext source to generate a 64 bit shared library.

ie what are the compiler and linker flags to do so

I tried
# ./configure CC='cc -m64' LD='ld -melfppc64'
# make
# make install

Still I am getting a 32 bit library..

If you are using a real compiler you just use +DD64. The gcc option is -mlp64.
The linker will automatically figure out the right thing. But you should be using cc instead: LD='cc +DD64'

[Harichand M V]

Problem is that when i try to compile gettext php extension as 64 bit elf i get error that 64 bit gettext library not found.

So i think i should install gettext library as 64 bit.
How can this be done.

Thanks in advance.
