I choose Lua 5.1 as my application's embedded scripting language, but when I port the application to a legacy platform runs LynxOS 3.1 on PowerPC,
things seems going wrong.
I get following code run up on PC and everything looks good:
const char *code = "foo = 5\n";
lua_State *L = luaL_newstate();
(void)luaL_loadbuffer(L, code, strlen(code), "line");
(void)lua_pcall (L, 0, 0, 0);
vfoo = lua_tonumber(L, -1);
myTrace("vfoo = %f", vfoo);
with PC (Visual C++ 6.0) I got expecting "vfoo = 5.000000"
But with LynxOS/PowerPC I got "vfoo = 0.000000".
So what's going on for Lua on LynxOS/PowerPC ? I am wondering if there are some configurations for big-endian machine, I looked for it in "luaconf.h" but find nothing. I also tried the configuration item "LUA_USE_POSIX" but no help.
I know it's not a typical platform for lua programming. However, any suggestions are welcome and be appreciated.
