66 llvm 3.2+ won't compile this demo. The reason is that this demo uses malloc which has to been compiled first from dlmalloc. However emscripten uses llvm-ld as the linker, which has been removed in llvm 3.2+, and the result is that you will encounter some strange error messages saying that "no such file or directory". If you get this message, check your llvm and clang version. |

66 Note that you must add "--preload-file hello_world_file.txt" in the command line. This line tells emcc that it should embed the file loading code into the js file. Before the application runs, all files will be loaded first. If you don't do this, it won't find this file. |
