使用codewarrior 注意點點

compile錯誤描述: reference to lable '233' is out of range

敘述:
在程式碼加上兩行程式碼
cmp.l #40,D0
beq  C_lable1
就發生錯誤..

花了挺多時間還是搞不懂，最後由david回答，特此紀念XD
david said:當發生reference to lable '233' is out of range ,此類無法判斷的錯誤訊息，需注意
1:程式碼寫法
2.前後文友寫跳躍的部份是否異常
結果證明是2，因為前面不遠處有短距跳躍 beq.s 敘述，在其後面加上了上面的兩行程式碼，結果造成距離過長跳躍不到所指向的label !!!!!!

話說，想想之前好像也遇到過一樣的問題，還是打上網誌不會忘記。錯誤描述只能參考用!!!

(咬 )文(嚼 )字

宏：「宏」指的是用一個字串代替另一個字串的功能。在makefile中可以使用「=」號來定義宏，使用「$（宏名）」來使用宏；還可以用「:=」追加宏的內容。習慣上，宏名使用大寫。

有一些編譯器輸出的代碼，將執行於與編譯器所在相同型別的電腦和作業系統之上，這種編譯器叫做原生編譯器。輸出可以執行於不同的平台之上的編譯器，叫做交叉編譯器。由於嵌入式系統通常沒有軟體開發環境，因此，為這類系統開發軟體時，通常需要使用交叉編譯器。
