Hello,
I'm trying to install emscripten on a new laptop with Ubuntu 12.04 (running
as a guest on VirtualBox) and I followed the guide and have installed:
-
- Ubuntu clang version 3.2-1~exp9ubuntu1~precise1
(tags/RELEASE_32/final) (based on LLVM 3.2)
- LLVM-3.2
This is my output when I try to test emscripten:
sashavm@UbuntuVM:~/emscripten$ ./em++ tests/hello_world.cpp
>
> /usr/lib/llvm-3.1/bin/llvm-nm: /tmp/tmpZMGXR8/hello_world_0.o: Unknown

And my .emscripten file is the following:

Can someone help me with this?
