I am following along in <a href="http://llvm.org/docs/GettingStartedVS.html">http://llvm.org/docs/GettingStartedVS.html</a> with a Hello World bitcode file. I can run the file using the command `lli HelloWorld.bc`, but now I want to link it into an executable file (on windows). The next thing the document says to run is `<span class="Apple-style-span" style="font-family: monospace; white-space: pre; background-color: rgb(238, 238, 238); font-size: medium; ">llc -filetype=obj HelloWorld.bc` which runs fine and now I have a `HelloWorld.obj` file. It's the last step that is giving me some trouble. The command `</span><span class="Apple-style-span" style="font-family: monospace; white-space: pre; background-color: rgb(238, 238, 238); font-size: medium; ">link hello.obj -defaultlib:libcmt` in MinGW yields the following error: `link: invalid option --d Try `link --help` for more information`. I drop the `-defaultlib:libcmt` and the linker creates an executable but when I try to run it I get the following errors:</span><div>
