未找到有关 opencv 的架构 i386 的符号 [英] symbol(s) not found for architecture i386 about opencv

问题描述

我现在正在学习opencv for ios，从github.com/macmade下载示例代码后，编译运行程序，一切正常.但是，当我添加一些 opencv 代码时:

I am studying opencv for ios now.After I download example codes from github.com/macmade, i complie and run the program, everything is OK. However, when i add some opencv codes as bellow:

IplImage* img = 0;
int height,width,step,channels;
uchar* data;
int hIndex,wIndex,cIndex;
img = cvLoadImage("tapme.png",CV_LOAD_IMAGE_COLOR);
if (!img) {
    NSLog(@"img cannot load");
    return;
}

height = img->height;
width = img->width;
step = img->widthStep;
channels = img->nChannels;
data = (uchar*)img->imageData;

NSLog(@"%d:%d:%d:%d",height,width,step,channels);

然后我再次编译程序，也一切正常.但是当链接时发生错误时:

Then i compile the program again, everything is OK too. But when errors happen when linking:

Undefined symbols for architecture i386:
"_cvLoadImage", referenced from:
-[MainViewController showPic:] in MainViewController.o

我已经尝试了几乎所有stackoverflow中的方法，但结果仍然不是那么好.任何人都有修复错误的好主意，等待您的帮助并感谢您.

I have tried almost all methods in stackoverflow, but the result is still not so good. Anyone have a good idea to fix the bug, waiting for ur help and thank u.

推荐答案

当您为模拟器构建时，链接器将需要一个适用于 i386 架构的库.当您为设备构建时，链接器将需要一个用于 arm 架构的库.您的模拟器构建设置是否指向正确的库?

When you build for the simulator, the linker will need a library for i386 architecture. When you build for a device, the linker will need a library for arm architecture. Do your simulator build settings point to the correct library?
