Write your question here.
I'm trying to create a dynamic library. I went to the projects options and click on the Parameters tab. Add a the library, but came
back with an [Build Error] [file.exe] Error 1. Also is in the MakeFile.win.I'm trying to link a .a library.

  Put the code you need help with here.
#include <iostream>
#include <cstdlib>
#include "dll.h"
using namespace std;
/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char** argv) {
	DllClass c;
	c.HelloWorld();
	system("PAUSE");
    return EXIT_SUCCESS;
}

/* Replace "dll.h" with the name of your header */
#include "dll.h"
#include <windows.h>

DllClass::DllClass()
{

}

DllClass::~DllClass()
{

}

void DllClass::HelloWorld()
{
	MessageBox(0, "Hello World from DLL!\n","Hi",MB_ICONINFORMATION);
}

BOOL WINAPI DllMain(HINSTANCE hinstDLL,DWORD fdwReason,LPVOID lpvReserved)
{
	switch(fdwReason)
	{
		case DLL_PROCESS_ATTACH:
		{
			break;
		}
		case DLL_PROCESS_DETACH:
		{
			break;
		}
		case DLL_THREAD_ATTACH:
		{
			break;
		}
		case DLL_THREAD_DETACH:
		{
			break;
		}
	}
	
	/* Return TRUE on success, FALSE on failure */
	return TRUE;
}

#ifndef _DLL_H_
#define _DLL_H_

#if BUILDING_DLL
#define DLLIMPORT __declspec(dllexport)
#else
#define DLLIMPORT __declspec(dllimport)
#endif

class DLLIMPORT DllClass
{
	public:
		DllClass();
		virtual ~DllClass();
		void HelloWorld();
};

#endif

You have to create two separate projects, one to create the DLL and another (with main) to use the DLL.

Orwell's Dev C++ fork is outdated, the GCC compiler is old.

Support for creating and using custom static and dynamic libraries is better IMO with Visual Studio 2015. VS 2015 Community is free.
