GNUstep Objective-C procedure entry point could not be located

I am new to Objective-C and I am using GNUstep to develop it on Windows. Each time I try to create a file, it compiles successfully but when I try to run the .exe I get a following error:

procedure entry point gzdirect could not be located in dynamic link library zlib1.dll

I don't know if this is caused by a system setting, how I compiled it, or from my source code but here is the compile command:

C:\gnustep\bin\gcc -o hello.exe hello.m -I /GNUstep/GNUstep/System/Library/Headers -L /GNUstep/GNUstep/System/Library/Libraries -std=c99 -lobjc -lgnustep-base -fconstant-string-class=NSConstantString

And here is the hello world source code:

#include <Foundation/Foundation.h>
int main()
{
  NSLog(@"Hello, world!");
  return 0;
}

Can anybody help me figure out what is causing this error?

The easiest way to build projects is to use a GNUmakefile text file (no extension) using your text editor:

include $(GNUSTEP_MAKEFILES)/common.make

TOOL_NAME = Hello
Hello_OBJC_FILES = hello.m

include $(GNUSTEP_MAKEFILES)/tool.make

Then you can compile your program by just running make at the GNUstep "Shell" command line.
