haXe Forum > Problem getting started with hxcpp

• Peter Mattsson Jan 30 at 13:51

  I'm trying to get a simple "Hello World" program compiled using Haxe cpp, but can't seem to get it working. The program is
  

  class Hello {
      static function main() {
          cpp.Lib.print("Hello World!");
      }
  }

  but compiling gives
  

  peter@HAL:~/haxe$ haxe -main Hello.hx -cpp Hello
  haxelib run hxcpp Build.xml haxe -Dcpp -Dhaxe_205 -Dtrue
  mkdir obj                                               
  mkdir obj/linux                                         
  mkdir obj/linux/src                                     
  mkdir obj/linux/src/cpp
  ... snipped ... (seems OK)

  This is with Haxe 2.05 on Ubuntu Karmic, and GCC 4.4.1. Compiling equivalent programs to SWF/Neko/etc works fine, and there are no issues with GCC that I can see.

  What am I doing wrong?

  Cheers,

  Adding

  #include <cstdio>

  to: /usr/lib/haxe/lib/hxcpp/2,05,1//src/hx/GCInternal.cpp
  works for me.

  Ah! Thanks for that. (Though, for reference, I had to do the same thing for StdLibs.cpp as well to get it working.)

  Cheers,

  Seconded. I gave up first time since this feels so n00bish.. but thanks!
  Looking at NME examples now :)

  That still doesn't seem to fix it for me. I'm on Windows and am getting this:
