c++ - 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。

。轮廓：

... 

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

主.cpp：

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 added symbols: DSO missing from command line collect2: error: Ld returned 1 exit status
