用QtCreator链接tesseract库
用QtCreator链接tesseract库
提问于 2016-04-05 13:08:28
我正在尝试运行一个基于tesseract API的C++程序，并在Ubuntu上使用QtCreator作为IDE，以便对页面布局进行分析：
int main(void)
{
int left, top, right, bottom;
tesseract::TessBaseAPI tessApi;
tessApi.InitForAnalysePage();
cv::Mat img = cv::imread("document.png");
tessApi.SetImage(reinterpret_cast<const uchar*>(img.data), img.size().width, img.size().height, img.channels(), img.step1());
tesseract::PageIterator *iter = tessApi.AnalyseLayout();
while (iter->Next(tesseract::RIL_BLOCK))
iter->BoundingBox( tesseract::RIL_BLOCK, &left, &top, &right, &bottom);
return EXIT_SUCCESS;
}但反过来，我得到了这样的错误，证实了tesseract和Qt之间没有关联：
main.cpp:11: error: undefined reference to `tesseract::TessBaseAPI::TessBaseAPI()'
main.cpp:12: error: undefined reference to `tesseract::TessBaseAPI::InitForAnalysePage()'
main.cpp:16: error: undefined reference to `tesseract::TessBaseAPI::SetImage(unsigned char const*, int, int, int, int)'
main.cpp:18: error: undefined reference to `tesseract::TessBaseAPI::AnalyseLayout()'这是我的.pro文件：

您只有lib -L"/usr/bin/tesseract"的路径，也忘记了包含lib。只需添加它，就像添加openCV库一样。
