请教一个TAAFont的问题?(宏定义相关)问题已解决!
TAAFont * AAFont = new TAAFont(tBitmap->Canvas);
AAFont->TextOutA(50, 250,"TEST", 50, 0);
C++ Builder报如下错:
[Linker Error] Unresolved external '__fastcall Aafont::TAAFont::TextOutA(int, int, System::AnsiString, signed char, signed char)' referenced from D:\BCB_PROJECT\20080407\UNIT1.OBJ
请问是什么回事?多谢了!
附我用的是2.63版本的AAFont
BCB版本为6.0

TAAFont 没有 TextOutA 方法,应该用 TextOut。

续:TAAFont
用TextOut也是一样的,报的错也是报 TextOutA无定义,所以如果写上TextOut,结果也一样报如下错:
[Linker Error] Unresolved external '__fastcall Aafont::TAAFont::TextOutA(int, int, System::AnsiString, signed char, signed char)' referenced from D:\BCB_PROJECT\20080407\UNIT1.OBJ
因为编译器会自动判断该用TextOutA还是TextOutW,一般头文件中会有如下定义:
#ifdef UNICODE
#define TextOut TextOutW
#else
#define TextOut TextOutA
#endif // !UNICODE
那如果没有定义TextOutA,而编译器又主张去调用,是否是产生这个问题的原因?

OH,原来是宏的问题
你可以试试在调用 TextOut 之前 #undef TextOut,看能不能解决?

回复 #4 zjy 的帖子
加了没有效果,还是报相同的问题。
不过还是要感谢zjy的关注!

把 #undef TextOut 放在 #include <vcl.h> 和 #include "AAFont.hpp" 中间,在BCB6下编译通过:
#include <vcl.h>
#pragma hdrstop
#undef TextOut
#include "Unit1.h"
#include "AAFont.hpp"
