Question

When i try to use emcc to convert the following code :

#include <iostream>
int main()
{
  std::cout << "hello, world!" << std::endl;
  return 0;
}

I get this error :

Traceback (most recent call last):
  File "./emcc", line 797, in <module>
    extra_files_to_link.append(shared.Cache.get(name, create))
  File "/home/user/emscripten/tools/shared.py", line 879, in get
    shutil.copyfile(creator(), cachename)
  File "/usr/lib/python2.7/shutil.py", line 82, in copyfile
    with open(src,  rb ) as fsrc:
IOError: [Errno 2] No such file or directory:  /tmp/emscripten_temp_MVh5qU/libcxx/libcxx.bc

I can convert any source that dont use std. I can generate the bytecode of the example above using clang and execute with lli.

I tried in two different machines(Linux 64) and had the same error.

Can someone help me to avoid this error?

It s been a while since the question was asked, but just to make remarks.

It does work on my osx 10.6.8, llvm 3.1 build from brew.

Only, the output of the 6 line code is about 113k lines and takes 4.8 MB space :)
The output for the tests/hello_world.cpp in emscripten source code is 2200 lines.
