Duplicate "_and" functions defined in compiled C++ files.

[SethSR]

Testing with a single file: Main.hx

import com.mindrocks.text.Parser;
class Main {
  static public function main() {
    trace ('Hello world');
  }
}

When I compile with: "haxe -lib Parsex -main Main.hx -cpp bin", I get the following:

include\Parsers.h(84) : error C2535: 'Dynamic Parsers_obj::_and(Dynamic,Dynamic)' : member function already defined or declared

Hummm... This appears to be a cpp target issue. Which Haxe version are you using?

Using the last Haxe stable version I have a different output

Ok, upgrading to latest hxcpp I have something more in line with your report.

Ok the name collision comes from improper cpp source file generation.

See the haxe 'and' function line 400 has cpp function name '_and'

Dynamic Parsers_obj::_and( Dynamic p1,Dynamic p2){
    HX_STACK_FRAME("Parsers","and",0x155073fd,"Parsers.and","com/mindrocks/text/Parser.hx",400,0xcffee55e)
    HX_STACK_ARG(p1,"p1")
    HX_STACK_ARG(p2,"p2")

And the haxe '_and' function line 405 has also cpp function name '_and'

Dynamic Parsers_obj::_and( Dynamic p1,Dynamic p2){
    HX_STACK_FRAME("Parsers","_and",0x8fb8c7f2,"Parsers._and","com/mindrocks/text/Parser.hx",405,0xcffee55e)
    HX_STACK_ARG(p1,"p1")
    HX_STACK_ARG(p2,"p2")

I'll modify generated code name for that function.

Hmm, it seems like I'm still getting the same error. I tried downloading Parsex from Haxelib, and implementing your fix directly, but @:native("__and") didn't seem to have any effect...
