C ++使用loadbuffer和runbuffer链接并运行LuaJit编译文件

Question

I have compiled test.lua with LuaJit into test.obj and test.h. How do I correctly use the loadBuffer or runBuffer functions that I have? All I need to find out is basically how to place test.lua, test.obj and test.h into the command but I just cant, Ive tried hundreds of ways but nothing seems to work. I have stripped some other functions off from main and so forth that it would just leave the problem visible and not other things that work just fine.

C++: This is the main

    int main(int argc, const char* argv[])
    {
        std::vector<std::string> args(argv, argv + argc);

        g_lua.loadBuffer("test.lua", "test.obj")
    // I have tried both, runBuffer and loadBuffer but I just cant get it right, it always fails.


    }

Here is the loadBuffer function:

void LuaCodes::loadBuffer(const std::string& buffer, const std::string& source)
{
    int ret = luaL_loadbuffer(L, buffer.c_str(), buffer.length(), source.c_str());
    if(ret != 0)
        throw LuaException(popString(), 0);
}

Here is the runBuffer function:

    void LuaCodes::runBuffer(const std::string& buffer, const std::string& source)
    {
        loadBuffer(buffer, source);
        safeCall(0, 0);
    }

Here are the insides of test.h:

#define luaJIT_BC_test_SIZE 1186
static const char luaJIT_BC_test[] = {

Answer 1

For luaL_loadbuffer (and hence LuaCodes::loadBuffer ) the 1st argument should be a string containing the bytecode and the 2nd argument should be a human-readable name (eg the filename that the bytecode was compiled from.)

Try:

#include "test.h"

// ...

int main(int argc, const char* argv[])
{
    // ...

    std::string bytecode(luaJIT_BC_test, luaJIT_BC_test_SIZE);
    g_lua.loadBuffer(bytecode, "@test.lua")
}
