POTrying to run the sample MacOSX FaceTracker program in XCode using OpenCV-2.3.1 installed via cmake
text
Body
copied!<p>Ok. I followed the "Using CMake to build" set of instructions on this site: <a href="http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port" rel="nofollow">http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port</a></p> <p>I made a "build" folder. I generated "Unix Makefiles" using cmake. I ran make -j8 and sudo make install. Everything should be where it needs to be, right? Wrong. I opened the FaceTracker.xcodeproj file, clicked "Run", and here's what I got:</p> <blockquote> <p>The run destination My Mac 64-bit is not valid for Running the scheme 'FaceTracker'.</p> <p>The scheme 'FaceTracker' contains no buildables that can be built for the SDKs supported by > the run destination My Mac 64-bit. Make sure your targets all specify SDKs that are supported by this version of Xcode.</p> </blockquote> <p>What should I do to get this to work? I'm scared to use the precompiled OpenCV packages on Lion considered how old they are. I'm also new to Xcode. </p> <p>Edit: December 14th, 7:05 PM:</p> <p>I made a helloworld program</p> <pre><code>//////////////////////////////////////////////////////////////////////// // // hello-world.cpp // // This is a simple, introductory OpenCV program. The program reads an // image from a file, inverts it, and displays the result. // //////////////////////////////////////////////////////////////////////// #include <stdlib.h> #include <stdio.h> #include <math.h> #include <cv.h> #include <highgui.h> int main(int argc, char *argv[]) { IplImage* img = 0; int height,width,step,channels; uchar *data; int i,j,k; if(argc<2){ printf("Usage: main <image-file-name>\n\7"); exit(0); } // load an image img=cvLoadImage(argv[1]); if(!img){ printf("Could not load image file: %s\n",argv[1]); exit(0); } // get the image data height = img->height; width = img->width; step = img->widthStep; channels = img->nChannels; data = (uchar *)img->imageData; printf("Processing a %dx%d image with %d channels\n",height,width,channels); // create a window cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE); cvMoveWindow("mainWin", 100, 100); // invert the image for(i=0;i<height;i++) for(j=0;j<width;j++) for(k=0;k<channels;k++) data[i*step+j*channels+k]=255-data[i*step+j*channels+k]; // show the image cvShowImage("mainWin", img ); // wait for a key cvWaitKey(0); // release the image cvReleaseImage(&img ); return 0; } </code></pre> <p>I tried compiling it with gcc:</p> <pre><code>gcc helloworld.cpp helloworld.cpp:12:16: error: cv.h: No such file or directory helloworld.cpp:13:21: error: highgui.h: No such file or directory helloworld.cpp: In function ‘int main(int, char**)’: helloworld.cpp:18: error: ‘IplImage’ was not declared in this scope helloworld.cpp:18: error: ‘img’ was not declared in this scope helloworld.cpp:20: error: ‘uchar’ was not declared in this scope helloworld.cpp:20: error: ‘data’ was not declared in this scope helloworld.cpp:29: error: ‘cvLoadImage’ was not declared in this scope helloworld.cpp:40: error: expected primary-expression before ‘)’ token helloworld.cpp:40: error: expected `;' before ‘img’ helloworld.cpp:44: error: ‘CV_WINDOW_AUTOSIZE’ was not declared in this scope helloworld.cpp:44: error: ‘cvNamedWindow’ was not declared in this scope helloworld.cpp:45: error: ‘cvMoveWindow’ was not declared in this scope helloworld.cpp:52: error: ‘cvShowImage’ was not declared in this scope helloworld.cpp:55: error: ‘cvWaitKey’ was not declared in this scope helloworld.cpp:58: error: ‘cvReleaseImage’ was not declared in this scope Jesse:testing jessebikman$ g++ helloworld.cpp helloworld.cpp:12:16: error: cv.h: No such file or directory helloworld.cpp:13:21: error: highgui.h: No such file or directory helloworld.cpp: In function ‘int main(int, char**)’: helloworld.cpp:18: error: ‘IplImage’ was not declared in this scope helloworld.cpp:18: error: ‘img’ was not declared in this scope helloworld.cpp:20: error: ‘uchar’ was not declared in this scope helloworld.cpp:20: error: ‘data’ was not declared in this scope helloworld.cpp:29: error: ‘cvLoadImage’ was not declared in this scope helloworld.cpp:40: error: expected primary-expression before ‘)’ token helloworld.cpp:40: error: expected `;' before ‘img’ helloworld.cpp:44: error: ‘CV_WINDOW_AUTOSIZE’ was not declared in this scope helloworld.cpp:44: error: ‘cvNamedWindow’ was not declared in this scope helloworld.cpp:45: error: ‘cvMoveWindow’ was not declared in this scope helloworld.cpp:52: error: ‘cvShowImage’ was not declared in this scope helloworld.cpp:55: error: ‘cvWaitKey’ was not declared in this scope helloworld.cpp:58: error: ‘cvReleaseImage’ was not declared in this scope </code></pre> <p>It seems like my problem is with the installed libs, but I am not really sure where to find them considering that my platform is not Linux, but OS X, and I didn't use Macports or Home Brew, I used the recommended method of installation, CMake. Do you know how I would set up PKG_CONFIG_PATH on my mac using the locations used by CMake? The installation instructions are extremely confusing, and it doesn't seem as though I would be able to use CMake to uninstall OpenCV, which is also quite confusing. </p>
