Question

在qt上编译出现以下问题，怎么解决？

/home/rong/qtworkplace/opencv_test_qt-build-desktop-Qt_4_8_1___PATH________/../opencv_test_qt/lbp.cpp:238: 错误:'_TCHAR' has not been declared
部分源代码：
int _tmain(int argc, _TCHAR * argv[])
{
IplImage *src,*grey,*result;
int samples,radius,range,*mapping;
MyPoint *spoint;
float Mi;

samples = 8;
radius = 10;
Mi = 2.0;
range = pow(Mi,samples);

src = cvLoadImage("test2.jpg");
grey = cvCreateImage(cvSize(src->width,src->height),IPL_DEPTH_8U,1);
cvCvtColor(src,grey,CV_BGR2GRAY);
mapping = (int *)malloc(sizeof(int)*range);
memset(mapping,0,sizeof(int)*range);

//计算采样点相对坐标
spoint = (MyPoint *)malloc(sizeof(MyPoint)*samples);
calc_position(radius,samples,spoint);

//计算灰度不变性LBP特征，写回浮点数图像矩阵中
//gray_invariant_lbp(grey,src->height,src->width,samples,spoint);

//计算旋转不变形LBP特征
//rotation_invariant_mapping(range,samples,mapping);
//rotation_invariant_lbp(grey,src->height,src->width,samples,spoint,mapping);

//计算旋转不变等价LBP特征
rotation_uniform_invariant_mapping(range,samples,mapping);
rotation_uniform_invariant_lbp(grey,src->height,src->width,samples,spoint,mapping);
return 0;
}

Answer 1

int main(int argc, char * argv[]) // 直接这样写
