I just installed Clang 3.5 on 64-bit Mint OS (version 17). I'm trying to compile my program in 32-bit, however I'm running into problems.
I have a file called test.cpp in my home directory with the following code:
#include <iostream>
int main()
{
std::cout << "Hello" << std::endl;
}
I then run the following command:
$ clang++ -m32 -Wl,--verbose test.cpp | grep libgcc
I get the following output:
$ clang++ -m32 -Wl,--verbose test.cpp | grep libgcc

I've done all of the Googling and self-investigation on this that I can, I'm not sure why this simple example isn't working. Can anyone help figure out what I'm missing?
You need to install a multilib g++ sudo apt-get install g++-multilib.
g++-multilib should also install all other required dependencies, such as libc6-i386.
