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 Building dependency tree Reading state information... 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 root@devserver:~/downloads# 3 Answers
You could've used apt-get install lib32stdc++6.
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.
The problem is not with libstdc++, it's with libpdf_php.so. You need to download the 32-bit version of that library.
