in project, build lua5.1 library "lfs"(https://github.com/keplerproject/luafilesystem) adding lfs.c , lfs.h in makefile of lua, works well.
but after upgrading lua5.3, fails this:
$ lua test.lua lua: test.lua:1: module 'lfs' not found: no field package.preload['lfs'] no file '/usr/local/share/lua/5.3/lfs.lua' no file '/usr/local/share/lua/5.3/lfs/init.lua' no file '/usr/local/lib/lua/5.3/lfs.lua' no file '/usr/local/lib/lua/5.3/lfs/init.lua' no file './lfs.lua' no file './lfs/init.lua' no file '/usr/local/lib/lua/5.3/lfs.so' no file '/usr/local/lib/lua/5.3/loadall.so' no file './lfs.so' stack traceback: [c]: in function 'require' test.lua:1: in main chunk [c]: in ? test.lua:

this have done , works well:
linit.c
added lfs in section:
static const lual_reg loadedlibs[] = { {"_g", luaopen_base}, ... {lua_lfslibname, luaopen_lfs}, and in lualib.h added
#define lua_lfslibname "lfs" luamod_api int (luaopen_lfs) (lua_state *l); then build usual. hope helps.
