Update the src/CMakeLists.txt file in the OpenALPR project. Update the following lines to match the directories of your libraries on your system:
|
||||
|
||||
* SET(OpenCV_DIR "../libraries/opencv/")
|
||||
* SET(Tesseract_DIR "/home/mhill/projects/alpr/libraries/tesseract-ocr")

- SET(OpenCV_DIR "../libraries/opencv/")
|

- SET(Tesseract_DIR "/home/mhill/projects/alpr/libraries/tesseract-ocr")
|
||||
|

Finally, in the src directory, execute the following commands:
|
||||
|
||||
* cmake ./
|
||||
* make
|
||||
- cmake ./
|

- make

If all went well, there should be an executable named *alpr* along with *libopenalpr.a* that can be linked into your project.
