Unable to load shared library gettext in php

Harichand M V — Wed, 21 Nov 2012 02:04:42 GMT

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.

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

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.

Exactly.

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

Re: Unable to load shared library gettext in php

# 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.

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'

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.

Does it exist at the porting center? If not, you will have to build and port it yourself.

I have found that i have to compile it as a 64 bit library

Thanks to all
