Constructor Details

#initialize(**kwargs) ⇒ Compiler

Checks for the AMX NetLinx compiler (third-party software, nlrc.exe) at the default installation path.

Parameters:

  • kwargs (Hash) —

    a customizable set of options

Options Hash (**kwargs):

  • :compiler_exe (String) — default: 'nlrc.exe'
  • :compiler_path (String) —

    Recommend a directory to look for the compiler_exe.

  • :use_wine (String) — default: false —

    Set to true to force ‘wine` at the front of the compiler command. This is automatic if nlrc.exe is installed at Wine’s default Program Files path.

Raises:
