错误tesseract qt

Question

我有一个奇怪的错误。 我想建立一个简单的例子。

.pro文件：

... 

LIBS += ... -llept 
LIBS += ... -ltesseract 

main.cpp中：

char *outText; 

tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI(); 
// Initialize tesseract-ocr with English, without specifying tessdata path 
if (api->Init(NULL, "eng")) { 
    fprintf(stderr, "Could not initialize tesseract.\n"); 
    exit(1); 
} 

// Open input image with leptonica library 
Pix *image = pixRead("/usr/src/tesseract-3.02/phototest.tif"); 
api->SetImage(image); 
// Get OCR result 
outText = api->GetUTF8Text(); 
printf("OCR output:\n%s", outText); 

// Destroy used object and release memory 
api->End(); 
delete [] outText; 
pixDestroy(&image); 

return 0; 

错误：

.../liblept.a(zlibmem.o): undefined reference to symbol 'deflate' error adding symbols: DSO missing from command line collect2: error: Ld returned 1 exit status

您必须将源文件（的.cpp）添加到的.pro文件。
