I have a simple plugin used to works in very old release, now it's not works, please help me. the line luaL_register (L,"mysolve", func_list); cause it crash when require it in Lua.
static int solve(lua_State *L)
{
.....
return 2;
}
static int generate(lua_State *L)
{
.......
return 2;
}
static int luaopen_solve(lua_State *L)
{
const luaL_Reg func_list[] =
{
{ "solve", solve },
{ "generate", generate },
{NULL, NULL}
};
luaL_register (L,"mysolve", func_list); // this line will not work now.
return 1;
}
static void g_initializePlugin(lua_State *L)
{
lua_getglobal(L, "package");
lua_getfield(L, -1, "preload");
lua_pushcnfunction(L, luaopen_solve, "plugin_init_mysolve");
lua_setfield(L, -2, "mysolve");
lua_pop(L, 2);
}
static int solve(lua_State *L)
{
.....
return 2;
}
static int generate(lua_State *L)
{
.......
return 2;
}
static int luaopen_solve(lua_State *L)
{
const luaL_Reg func_list[] =
{
{ "solve", solve },
{ "generate", generate },
{NULL, NULL}
};
luaL_register (L,"mysolve", func_list); // this line will not work now.
return 1;
}

lua_getglobal(L, "package");
lua_getfield(L, -1, "preload");

lua_setfield(L, -2, "mysolve");
lua_pop(L, 2);

At first sight your code seems to be still compatible with recent gideros. Doesn't it send any meaningful message in Gideros Studio's console ?
Can you try to change the register line like below and see if that helps/go further ?
com.giderosmobile.android.player.LuaException: assign to undeclared variable 'mysolve'
stack traceback:
[string "libs/strict.lua"]:28: in function <[string "libs/strict.lua"]:24>
[string "luabinding/compatibility.lua"]:69: in function require

at LUA.require(string_luabindingcompatibility.lua:69)
at LUA.string_jsovlelua1(string_jsovle.lua:1)
luaL_register(L, NULL, func_list);
after change to this, it will not exit on require "mysolve"
but when call mysolve.generate, it exits

On the other hand, when lua_regsiter is called with NULL, the global variable is not created at all, which your code seems to depend on.
