Hi! This particular issue is caused by luarocks trying to extract Lua version from lua.h in /usr/include/lua5.5 and checking if it is indeed 5.5. This fails because Lua 5.5 changes the way its version is defined in lua.h:
Lua 5.4: #define LUA_VERSION_NUM 504 Lua 5.5: #define LUA_VERSION_NUM (LUA_VERSION_MAJOR_N * 100 + LUA_VERSION_MINOR_N) There are two commits upstream to support Lua 5.5: https://github.com/luarocks/luarocks/commit/291fc8a34fc186b011c9d6b09a80bf179cae6f62 https://github.com/luarocks/luarocks/commit/ee8194313e61c9d0d7b8a0d52d22b026a06282bb I guess they can be applied to the luarocks in Debian (probably with some modifications) until 3.13 can be packaged. Cheers! -- Sergei Golovan
