8111 :: gcc does not find paths generated by os module on Windows

• greenfork (orginal) [2021-06-13T04:33:42+02:00] view original

  There are errors with gcc.exe not able to find the required paths (original issue https://github.com/greenfork/nimraylib_now/issues/38):

  
  gcc.exe: error: User.nimble\pkgs\nimraylib_now-0.13.1\csources\raylib_mangled: No such file or directory
  Run

  where this path is fetched via (full code https://github.com/greenfork/nimraylib_now/blob/master/src/nimraylib_now/raylib_build_static.nim#L15)

  # src/filenames.nim
  from os import `/`, parentDir
  
  const
    srcDir*                      = currentSourcePath().parentDir()
    cSourcesDir*                 = srcDir/"csources"
    raylibMangledCSourcesDir*    = cSourcesDir/"raylib_mangled"
  Run

  # src/nimraylib_now/raylib_build_static.nim
  from os import parentDir, relativePath, `/`
  import ../filenames
  
  const
    CurrentDirectory = currentSourcePath().parentDir()
    RaylibSrcPath = raylibMangledCSourcesDir
    RaylibSrcPathRelative = relativePath(RaylibSrcPath, CurrentDirectory)  # This one is the path from error
  Run

  the error says that RaylibSrcPathRelative is not a valid directory.

  What's up with User.nimble, where's the slash? How do I even debug this? Others have no problems on Windows. Is there any particular information I could ask to resolve this?

  You can see parameters passed from Nim to gcc by adding --listcmd option when you run Nim.

  You can echo a value of RaylibSrcPath or CurrentDirectory at compile time by using static statement. That might help for debug.

  For example, add static statement like this to src/nimraylib_now/raylib_build_static.nim after the const section:

  import sugar
  
  const
    CurrentDirectory = currentSourcePath().parentDir()
    RaylibSrcPath = raylibMangledCSourcesDir
    RaylibSrcPathRelative = relativePath(RaylibSrcPath, CurrentDirectory)
  
  static:
    dump CurrentDirectory
    dump RaylibSrcPath
  Run
