/usr/bin/ld: cannot find -lstdc++

When I make a program from source, I get this error:

Code:

I don't know why it complain about libstdc++ because I have installed it

Code:

Maybe it's looking for libstdc++5. Many systems provide the older libstc++ for compatibility. For examples Red Hat provides the package compat-libstdc++-33. Ubuntu provides libstdc++5 and ia32-libs.

How can I find which version is required?

Still using Ubuntu ? Which version ?

Is this about osprey → Open64 ?
http://svn.open64.net/listing.php?re...sprey%2F&rev=0
http://www.open64.net/home.html
http://www.open64.net/download/open64-4x-releases.html

Yes that is possible. I downloaded from AMD site.

By default, on x86_64 machines, the osprey compiler will be built in
32bit mode and libraries will be built in 32 and 64 bit modes to support
compilation in either mode. See "HOWTO-INSTALL-* and other documentation.

A 32bit libstdc++ library is required ( to create some objects.)
Ubuntu 10.04, amd64 : sudo apt-get install g++-4.4-multilib

The binary osprey 'open64-4.2.4-0.x86_64.rpm' works perfect on Ubuntu 10.*
https://sourceforge.net/projects/ope...4.rpm/download
sudo rpm -Uvh --nodeps open64-4.2.4-0.x86_64.rpm
