Guys,
I'm using luajit as a shared library (libluajit.so) embedded in an C++ app.
I've a shared library provided by a third party vendor (libctosapi.so) when
trying to call a C function in this library from LUA using ffy I get
'undefined symbol'.
Any kind of help is appreciated!
*LUA Script (script.lua)*
local ffi = require("ffi")
ffi.cdef[[
unsigned short CTOS_PrinterPutString(unsigned char* baBuf);
]]
local ctosapi = ffi.load("ctosapi")
x = 0
for i = 1, #foo do
x = x + foo[i]
ctosapi.CTOS_PrinterPutString("Test")
end
return x
*C++ Main*
int main(int argc,char *argv[])
{
BYTE key;
CTOS_LCDTClearDisplay();
int status, result, i;
double sum;
lua_State *L;
L = luaL_newstate();
luaL_openlibs(L); /* Load Lua libraries */
status = luaL_loadfile(L, "script.lua");
if (status) {
/* If something went wrong, error message is at the top of */
/* the stack */
fprintf(stderr, "Couldn't load file: %s\n", lua_tostring(L, -1));
exit(1);
}
lua_newtable(L); /* We will pass a table */
for (i = 1; i <= 5; i++) {
lua_pushnumber(L, i); /* Push the table index */
lua_pushnumber(L, i*2); /* Push the cell value */
lua_rawset(L, -3); /* Stores the pair in the table */
}
lua_setglobal(L, "foo");
result = lua_pcall(L, 0, LUA_MULTRET, 0);
if (result) {
fprintf(stderr, "Failed to run script: %s\n", lua_tostring(L, -1));
ABI_PrinterPutString((UCHAR *)lua_tostring(L, -1));
exit(1);
}
sum = lua_tonumber(L, -1);
if (sum == 30)
ABI_PrinterPutString((UCHAR *)"SUCCESS!!!");
lua_pop(L, 1); /* Take the returned value out of the stack */
lua_close(L); /* Cya, Lua */
CTOS_KBDGet(&key);
exit(0);
}
