28335 無法使用IQMATH

#include "DSP2833x_Device.h"

#include "DSP2833x_Examples.h"
#include "IQmathLib.h"

_iq in1,out1;

_iq30 in2,out2;

int main(void) {

in1=_IQ(1.8);
out1=_IQisqrt(in1);
in2=_IQ30(1.8);
out2=_IQ30isqrt(in2);

}

這是小弟我看說明書寫的

可是Debug以後出現

#10010 errors encountered during linking; "test1.out" not built

#10234-D unresolved symbols remain

gmake: *** [test1.out] Error 1

gmake: Target 'all' not remade because of errors.

unresolved symbol __IQ24isqrt, first referenced in ./main.obj

unresolved symbol __IQ30isqrt, first referenced in ./main.obj

這6種錯誤(如附圖)

可以幫小弟我解惑嗎?謝謝

mangui zhang：

除了包含头文件外  还要cmd和.lib吧

#include "DSP2833x_Device.h"

#include "DSP2833x_Examples.h"
#include "IQmathLib.h"

_iq in1,out1;

_iq30 in2,out2;

int main(void) {

in1=_IQ(1.8);
out1=_IQisqrt(in1);
in2=_IQ30(1.8);
out2=_IQ30isqrt(in2);

}

Young Hu：

回复 mangui zhang:

应该是.lib没有加进来。

#include "DSP2833x_Device.h"

#include "DSP2833x_Examples.h"
#include "IQmathLib.h"

_iq in1,out1;

_iq30 in2,out2;

int main(void) {

in1=_IQ(1.8);
out1=_IQisqrt(in1);
in2=_IQ30(1.8);
out2=_IQ30isqrt(in2);

}

Chien Chien Chou：

你們是指C2000 Linker 的file search path還有Compiler的include option是嗎?(如附圖)

我把lib include cmd gel 都加了可是還是不行
