C++ Help / Gamelib

[jaydubeww]

Hi all, I'm new to C++ and having a bit of trouble compiling the basic LEBuilder Gamelib project. I added all the include/search directories and now I receive these build errors:

 

Also note: I haven't changed anything to the files. The Error occurs on the last line in the .cpp; RunClass(main).

 

||=== main, Release ===|
C:Programmingprojects_codeblocksbasic_frameworkmainsourcesrcmain.cpp||In function 'int main(int, char**)':|
C:Programmingprojects_codeblocksbasic_frameworkmainsourcesrcmain.cpp|32|error: expected ';' before 'app'|

C:Programmingprojects_codeblocksbasic_frameworkmainsourcesrcmain.cpp|32|error: 'app' was not declared in this scope|
||=== Build finished: 2 errors, 2 warnings ===|

 

the RunClass() definition in Application.h

namespace GameLib
{
#define RunClass(UserApp,...)
int main(int argc, char* argv[])
{
 /*chdir(__VA_ARGS__);*/
 UserApp app(argc,argv);
 app.Load();
 app.Run();
 return app.GetResult();
}

 

 

the .h

#pragma once
#include "GameLib.h"   // GameLib
#define APPNAME "main"
#define APPVER "0.0.0.0"
class main : public Application
{
public:
main(int argc, char* argv[]); // Constructor
void RenderActive3D();  // Overridden 3D rendering
void RenderActive2D();  // Overridden 2D rendering
Cube cube, ground;   // Create cube and ground
void Load();	// Overridden scene loading and population stuff
Material material;   // Material for cube and ground
DirectionalLight sun;  // Create sun
};

 

the .cpp

#include "main.h"
main::main(int argc, char* argv[]):
Application("data",APPNAME" "APPVER)
{
// TODO: Add stuff here which is done once per application launch
}
void main::Load()
{
game.scene.cam.Move(0,0,-2);
sun.Turn(Vec3(45));
material.Load("Models/CobbleStones/CobbleStones.mat");
cube.Paint(material);
ground.Paint(material);
ground.Scale(Vec3(10,1,10));
ground.SetPosition(Vec3(0,-2,0));
}
void main::RenderActive3D()
{
if(Keyboard::I****()) Quit();
double n=AppSpeed();
cube.Turn(n,n*2,0);
}
void main::RenderActive2D()
{
Draw::Text(50,50,"%0.0f",FPS());
}
RunClass(main);

Metetron usualy answers gamelib questions. He hasn't been around lately. Maybe he has gone to look for lummooja

I think you can't call a class "main", because it conflicts with the main function. You could call it "Main" though, and class names should always start with capital letter.

Says who?

[jaydubeww]

Metatron was right, my main class 'main' was interfering with Gamelibs method 'main'.

 

Now it seems to be looking for OpenGL commands.

I figured I should add 'C:/mingw/lib' to my search directory, but that didn't help.

Note: These are not all of the errors, but I figured you got the jist of it.

I'd check the GameLib tutorials, but those seem to be down quite often..
