[cfe-users] Basic clang usage fails for 32-bit

[Robert Dailey]

First here is my version of clang:

$ clang --version
Ubuntu clang version 3.5-1ubuntu1 (trunk) (based on LLVM 3.5)
Target: x86_64-pc-linux-gnu
Thread model: posix

I'm running the following command:

$ clang++ -m32 -Wl,--verbose test.cpp|grep libgcc

And I get the output below. I'm running Mint 17 64-bit, it's a fresh
install. I've installed the following packages:

clang, g++-multilib

What is going on? Why can't I compile a 32-bit application?
