Compilation Errors

[AndrewChicco]

Hi,
I'm getting some major compilation errors attempting to compile a very simple program
(using Ubuntu 15.x with G++ 4.9.2).

These problems appeared when I added in all the selene specific code in the main function.

Can someone let me know if I'm doing something terribly wrong.

Please excuse my ignorance if I've done something very obviously wrong.

Thanks,
Andrew

include <selene.h>

include

include

using namespace std;
using namespace sel;

int main()
{
State state;
state.Load("./test.lua");
assert(state["foo"] == 4);
assert(state["bar"][3] == "hi");
assert(state["bar"]["key"] == "there");

// basic checking
cout << "Hello world!" << endl;
return 0;
}

-- test.lua
foo = 4
bar = {}
bar[3] = "hi"
bar["key"] = "there"

It seems your commandline g++ -o bin/Debug/LUATest obj/Debug/main.o misses parameters to link the Lua libraries.

Hi AnonymousProgrammerLandau,
Much thanks for the hint. It seems to be all working now.
I was just missing the '-llua5.2' for the linking stage.
