bits/c++config.h no such file or directory [duplicate]

Question

I'm trying to compile my code including iostream lib on ubuntu 14.04, using qt creator, but when I execute it I got this error message:

/usr/include/c++/4.8/iostream:38: error: bits/c++config.h: No such file or directory #include <bits/c++config.h>

Even if I try to compile it by terminal, I have the same trouble. This is a c code that i got from my friend, not c++, but I still need to include this iostream. I made a huge research and can't find anything useful on internet, just posts talking about 64 or 32 bits OS. I'm new on programming scene, I'm glad for your patience, thanks.

Answer 1

It does look like a cross-platform compilation issue. Did you install the multilib packages:

sudo apt install gcc-multilib g++-multilib

If you've installed a version of gcc / g++ that doesn't ship by default you'll want to match the version as well:

sudo apt-get install gcc-4.8-multilib g++-4.8-multilib
