wrong import order in the c files (tested on windows)

[enthus1ast]

Another flavour of:

main.nim

import os
import nimraylib_now/mangled/raylib  # Vector2
import nimraylib_now/mangled/raymath # Vector2
import moduler
initWindow(20, 20, "thread bug")

var threadPhysic: Thread[int]

createThread(threadPhysic, threadSystemPhysic, 10)
while true:
  var vv = Vector2(x: 0.1, y: 0.2) + 0.1  # <- this uses raymath.h ; and let nim include it in the c file
  sleep(500)
closeWindow()

moduler.nim

import nimraylib_now/mangled/raylib  # Vector2
import nimraylib_now/mangled/raymath # Vector2
import os

proc threadSystemPhysic*(foo: int) {.thread.} =
  discard
  while true:
    echo "tick"
    sleep (100)

compile with:

nim c --threads:on main.nim

as soon a proc from raymath.h is used in the main.nim the c includes are in the wrong order (windows.h is moved above the raymath.h include):

#include "nimbase.h"
#include "C:\Users\david\projects\nimraylib_now\src\nimraylib_now\mangled\raylib.h"
#include <windows.h>
#include <setjmp.h>
#include <string.h>
#include "C:\Users\david\projects\nimraylib_now\src\nimraylib_now\mangled\raymath.h"

The problem is not present on arch linux. Further investigation is needed.

EDIT: lol the problem is with windows.h, it's not linux for sure

If you need me for testing let me know

@enthus1ast I invited you as a collaborator to the project. So here you would want to read a bit about HACKING. I made a PR https://github.com/greenfork/nimraylib_now/pull/51 that does name mangling for more names, you would want to get this branch and add more names as needed, then run nimble convert to regenerate all the files and try to compile your example again. Eventually all conflicting symbols will be resolved.

You would also want to run nimble develop in the project root to avoid reinstalling this package everytime.

Let me know if you need any help with that.
