We have a new application that requires glibc 2.4 (from gcc 4.1). The machine we have runs on has gcc 3.4.6. We can not upgrade, and the application must be run on this machine.
We installed gcc 4.1, however, when it comes to compile time it is using all the includes, etc, from 3.4.6.
How do we get around this?
Any suggestions on using 4.1 for just this application?

C++17 Support in GCCThis mode is the default in GCC 11; it can be explicitly selected with the -std=c++17 command-line flag, or -std=gnu++17 to enable GNU extensions as well.
According to cppreference, full support of c++11 came with gcc 4.8. 1; To have full support of c++14 (with some of the new features of c++17), instead, you need gcc 5.0 and above.
Refer "How to install multiple versions of GCC" here in the GNU GCC FAQ.
There's also a white paper here.

for Ubuntu it's pretty easy
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
and then install for example gcc version 6
sudo apt-get install gcc-6
