以下是我執行NIOS II執行C2H的ERROR訊息..
& ^6 C' \8 P5 ^1 I我只有把synth_full改C2H執行..

) q3 b& Q  c. ^( c- X上面的錯誤訊息是什麼意思呀!?
6 \2 k/ a4 e1 [synth_full calls dct32 意思是說有呼叫到dct32..
所以要把dct32也用成C2H嗎..
我把dct32也用成C2H後這行就不見了..
但是其他都還在捏 >"<
還有以下這些是要幹嘛的？
4 p7 k6 K1 a2 g0 o4 |7 h# K只是說這一個C檔裡有這些副函式而已嗎??
# ^+ c/ c# k, S5 l5 ?! D還是有關C2H不能編譯過的關鍵呢？

' x  x& m7 w1 I是因為哪裡沒有用好導致C2H不能成功呀!?

請各位大大幫忙一下呀~~
