ACDK Hello World

To get a first impression, here is a simple project written in ACDK.

The Project Workspace acdk_boot

The Project acdk_boot is provided to demonstrate a basic ACDK project with a modules DLL/SO, an executable and a testing unit. Please refer also to:

!	The sample is a little bit outdated. For sample code, please refer to the acdk_boot package.

Start and configurate a ACDK Project

First, create a new workspace directory with: $> mkdir /path/to/My/acdk_workspace
Then, create a project directory inside your ACDK workspace.
For source files, make a directory structure like
"My/acdk_workspace/Project/src/Project"
and put your source files in the directory "Project/src/Project."
Create the config file "Project.lsp" and edit it in the directory "acdk_workspace/Project/src"
with your project settings.
Create the makefiles for the gcc compiler with acdklisp or dsp files for MS VC++,
using the following commands:
$>acdklisp Project.lsp $target #target is the compiler you use $>acdklisp Project.lsp linux #target is linux $>acdklisp Project.lsp dsp #target is MS VC++
The result is "Project.target", which is the makefile for unix systems
and a projectfile on Win32 platforms.

HelloACDK Step by Step

For our first project, we need to edit the Project.lsp file. In this example, we will call it HelloACDK.
We create a directory called "HelloACDK", which is the projectdirectory. Then, we need a source directory
"src". We now copy the file "HelloWorld.lsp" from acdk_boot in the source directory and edit it.


$>cp ACDK_HOME/acdk_boot/src/HelloWorld.lsp /path/to/My/acdk_workspace/HelloACDK/src/HelloACDK.lsp

open "HelloACDK.lsp" and edit this file. First, you have to change the projectname in line 28.


28: (setg acdkmake-project-name  "HelloWorld") ;;; replace this name


28: (setg acdkmake-project-name  "HelloACDK") ;;; replace this name

In line 33, you are able to change the binary directory for the compiler and default, is the path to
the acdk binary directory "ACDK_HOME/bin". Change line 33 from


33: (setg acdkmake-project-exec-dir (s+ acdk-home "/bin" (if ...


33: (setg acdkmake-project-exec-dir (s+ "My/acdk_workspace/bin" (if ...

In line 62, we change the path to source files for our project.


62: "acdk/HelloWorld.cpp"


62: "HelloACDK/HelloACDK.cpp"

Currently, we have the file HelloACDK.cpp. We now start acdklisp using the following command.


$>acdklisp HelloACDK.lsp linux #target is linux
$>acdklisp HelloACDK.lsp dsp   #target is MS VC++

When acdklisp is completed, we find the file "HelloACDK.linux" in the "src" directory, which
is the makefile for linux and "HelloACDK.dsp," the projectfile for VC++. We are now able to compile the HelloACDK
project under linux with


$>make -f HelloACDK.linux

and under Windows with MS VC++. You find binary files in the directory, which
you have entered into the file of "HelloACDK.lsp" in line 33.

The source code

You can find the source file in the acdk_tutorial directory.


// including ACDK-declarations
#include <acdk.h>
// include needed ACDK-Classes
#include <acdk/lang/System.h>
#include <acdk/lang/StringBuffer.h>

// import namespace

ACDK_DECL_CLASS(HelloACDK);

class HelloACDK
: extends ::acdk::lang::Object
{
public:
  static int acdkmain(IN(RStringArray) args);
  void getMessage();
  

};

void
HelloACDK::getMessage()
{
  System::out->println("Hello First User ;-)");
}

int
HelloACDK::acdkmain(RStringArray args)
{
  RHelloACDK hello = new HelloACDK();
  hello->getMessage();
  return 0;
}

int main(int argc, char* argv[], char** envptr)
{
  // enter acdk's world
  return acdk::lang::System::main(HelloACDK::acdkmain, argc, argv, envptr);
}
