@rem Script to build LuaJIT with NintendoSDK + NX Addon.
@rem Donated to the public domain by Swyter.
@rem
@rem To run this script you must open a "Native Tools Command Prompt for VS".
@rem
@rem Either the x86 version for NX32, or x64 for the NX64 target.
@rem This is because the pointer size of the LuaJIT host tools (buildvm.exe)
@rem must match the cross-compiled target (32 or 64 bits).
@rem
@rem Then cd to this directory and run this script.
@rem
@rem Recommended invocation:
@rem
@rem nxbuild # release build, amalgamated
@rem nxbuild debug # debug build, amalgamated
@rem
@rem Additional command-line options (not generally recommended):
@rem
@rem noamalg # (after debug) non-amalgamated build
