+Subject: [PATCH] Do not include compat-5.3.h in luv header file
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+Do not include compat-5.3.h in luv header file
+
+Exposing the compat-5.3.h header file directly in the luv.h header file
+is not a good idea, because it causes redefinition errors when building,
+for example latest luvi version 2.8.0, with a shared luv library and
+LuaJIT 2.0.5.
+
+Therefore, include the compat header file in the luv.c source file.
+
+Note, that luvi version 2.8.0 (and 2.7.6) still fails to build against the
+shared luv library using LuaJIT 2.0.5, as it does use `luaL_newlib` which is
+not available in Lua 5.1. However, this is unrelated to the luv library as
+luvi itself should define the macro for Lua 5.1.

+Subject: [PATCH] Add missing define for luaL_newlib for Lua 5.1
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Since commit c286f3b741d0968fd1c49c28da83bc723468ecba, which bumped the
+library luv to version 1.22.0-1, building luvi fails.
+
+The reason for this error is, that instead of defining Lua 5.3 API itself,
+luv now [1] uses lua-compat-5.3 [1,2] for providing a Lua 5.3 API.
+
+Unfortunately, upstreams "luv.h" now exposes "compat-5.3.h" directly, causing
+redefinition errors when building luvi 2.7.6 (as well as latest release 2.8.0)
+with luv 1.22.0-1. Instead, "compat-5.3.h" should only be included in "luv.c",
+which is addressed in patching luv (Patch: "Do not include compat-5.3.h in luv
+header file").
+
+Patching luv reveals an issue in luvi itself, as it is using the Lua 5.3 API,
+without defining the Lua 5.3 itself, nor using lua-compat-5.3. Instead, it was
+using the definition provided by the "luv.h" file in luv versions before 1.22.0.
+
+Correctly, luvi should define the necessary Lua 5.3 itself, which is done by
+this patch, by providing a definition for `luaL_newlib`.
+
+Note, that this patch is not upstreamable, as upstream already switched to
+using lua-compat-5.3 [3,4]. However, backporting this patch set is to much of a
+burden, so we keep it simple, by just defining `luaL_newlib`.
