詢問一下C2H的錯誤訊息意思

static314

以下是我執行NIOS II執行C2H的ERROR訊息..
7 e3 d) k" w0 l2 P我只有把synth_full改C2H執行..

請問一下各位大大...
% b' u  e# D9 ]上面的錯誤訊息是什麼意思呀!?
: _# `0 F" c3 \5 c5 q7 @2 O) nsynth_full calls dct32 意思是說有呼叫到dct32..
所以要把dct32也用成C2H嗎..
: N2 V* S2 Y. ^9 c" I2 Y6 a6 R我把dct32也用成C2H後這行就不見了..
, X- i5 e7 n3 B+ c1 Z2 C% j, M但是其他都還在捏 >"<
還有以下這些是要幹嘛的？
只是說這一個C檔裡有這些副函式而已嗎??
還是有關C2H不能編譯過的關鍵呢？

最後這行我覺得應該是C2H不能成功的最大問題！
$ W% y  \; v3 }9 j7 y, Q; p" emaking hdl for subroutine named dct32
( y6 A9 l& l1 j3 U+ D這問是什麼意思呢？
- ]2 W  B" q) e4 p. I- x/ t是因為哪裡沒有用好導致C2H不能成功呀!?
卡好多天了..一直找不到相關的資料
' N* b4 q# y! A0 H# z- R請各位大大幫忙一下呀~~
