Hi again. I grepped the new release and I see permitloadlib is already included in mtxrun. Just out of curiosity, is --permitloadlib called via context or should I use it from mtxrun? context --permitloadlib file.tex still doesn't have any effect. Best wishes, Jairo :) El mié., 4 de nov. de 2020 a la(s) 06:44, Hans Hagen (j.hagen@xs4all.nl) escribió:

Hi. I've just read in the LuaMetaTeX manual that --permitloadlib allows loading compiled (.so/.dll) libraries. However, when I try it using ConTeXt I have an error message (example below):

%hello.tex

\starttext

\startluacode

local hello = require"hellolib" -- hellolib.so

context(hello.helloworld())

\stopluacode

\stoptext

%hello.c #include #include

static int helloworld (lua_State *L) { char hello[] = "Hello world!"; lua_pushstring(L, hello); return 1; }

static const struct luaL_Reg hellolib [] = { {"helloworld", helloworld}, {NULL, NULL} };

int luaopen_hellolib (lua_State *L){ luaL_newlib(L, hellolib); return 1; }

error (lua loadlib): you can only load external libraries when --permitloadlib is given

On the other hand, manually calling LuaMetaTeX with the ConTeXt format and --permitloadlib gives the expected result (in this case, a "Hello world!").

How is the correct way to load those libraries? Thank you very much and sorry if my question seems to be weird. i should add a --permitloadlib option to the context runner then
