I need to install the 32-bit version of libstdc++.so.6 on a 64 bit Ubuntu 8.04.2 server.



when i tried apt-get install ia32-libs, it says



root@devserver:~/downloads# apt-get install ia32-libs
Reading package lists... Done

ia32-libs is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 133 not upgraded.


But when i tried to enable a PHP extension (libpdf_php.so), which uses this runtime library following error is logged in php error log.



root@devserver:~/downloads# cat /var/log/apache2/php_error.log
[01-Nov-2011 16:54:09] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20060613/libpdf_php.so' - /usr/lib/php5/20060613/libpdf_php.so: wrong ELF class: ELFCLASS32 in Unknown on line 0

What makes you think you need a 32-bit version of libstdc++.so.6?



64-bit Ubuntu runs 64-bit Apache which runs 64-bit PHP which it seems can't load 32-bit libpdf_php.so, which it tells you in the error message.



It's unlikely that installing ia32-libs will solve the problem - I would say you need 64-bit version of libpdf_php.so



It looks like pdflib's website has a separate download for x86-64 architecture - I downloaded the archive and the .so file inside it is definitely 64-bit.
