BREWコンパイル調査 by gnude

C++機能の検証

gnudeでのコンパイルによってC++の機能がどこまで使用できるかを検証する。

使用するソース

以下に示す二つのファイルをコンパイルした。尚、機能はHelloWorldとほぼ同等である。

gccex1.cpp

#include "AEEModGen.h" // Module interface definitions
#include "AEEAppGen.h" // Applet interface definitions
#include "AEEShell.h" // Shell interface definitions
#include "gccexImpl.cpp"
#include "gccex.bid"

extern "C" {
    int AEEClsCreateInstance(AEECLSID ClsId,IShell * pIShell,IModule * pMod,void ** ppObj)
    {
     *ppObj = NULL;

     if(AEEApplet_New( sizeof(AEEApplet), // Size of our private class
                         ClsId, // Our class ID
                         pIShell, // Shell interface
                         pMod, // Module instance
                         (IApplet**)ppObj, // Return object
                         (AEEHANDLER)HelloWorld_HandleEvent, // Our event handler
                         NULL)) // No special "cleanup" function
         return(AEE_SUCCESS);

        return (EFAILED);
    }
}

gccexImpl.cpp

#include "AEEAppGen.h" // Applet interface definitions
#include "AEEShell.h" // Shell interface definitions
#include "AEEStdLib.h"

/**
* namespace test
*/
namespace test
{
    class TestClass
    {
        int value;

    public:
        TestClass(int v) : value(v){}
        int getValue(){return value;}
    };
};

static void showText(AEEApplet * pMe, const AECHAR* szText)
{
IDISPLAY_DrawText(pMe->m_pIDisplay, // Display instance
AEE_FONT_BOLD, // Use BOLD font
szText, // Text - Normally comes from resource
-1, // -1 = Use full string length
0, // Ignored - IDF_ALIGN_CENTER
0, // Ignored - IDF_ALIGN_MIDDLE
NULL, // No clipping
IDF_ALIGN_CENTER | IDF_ALIGN_MIDDLE);
IDISPLAY_Update (pMe->m_pIDisplay);
}

static boolean HelloWorld_HandleEvent(AEEApplet * pMe, AEEEvent eCode, uint16 wParam, uint32 dwParam)
{
AECHAR szText[] = {'H','e','l','l','o',' ','W','o', 'r', 'l', 'd', '\0'};
AECHAR szThrowText[] = {'T','H','R','O','W',' ','W','o', 'r', 'l', 'd', '\0'};

switch (eCode){
case EVT_APP_START:
         {

            try
            {
//                throw szThrowText;
                showText(pMe, szText);

                test::TestClass cls(3);
                DBGPRINTF("namespace test: %d", cls.getValue());

            }
            catch(const AECHAR* sz)
            {
                showText(pMe, sz);
            }

            return(TRUE);
         }

case EVT_APP_STOP:
return(TRUE);

default:
break;
}
return(FALSE);
}

結果

上記のソースコードにより、namespace及び例外を使用したプログラムをコンパイルすることを試したが、例外に関しては下記のようなリンカエラーが発生してしまった。

例外は使用できないようだ。

namespaceは簡単な使用に関しては問題なさそうだ。
