@ggibson, I was able to run your first example (the "importcpp") with additional
{.passC: "-Inimcache".}
at the very top of main.nim . I don't know why but the error (the cannot find symbol error) was generated because nimcache folder wasn't included in path, so you need to add passC pragma. Oh, I'm using vcc, I still haven't tried using clang.
