Error : While Building recognizer executable

[bhargavravat]

Hi @DoubangoTelecom :

I am trying to build executable of recognizer , however unable to build it.

I followed steps given in README.md .

Here is the error output. ****

Here is the exact log of the output:

I am into directory :
/data/ultimateALPR-SDK/samples/c++/recognizer

This is the command which I am running :
g++ recognizer.cxx -O3 -I../../../c++ -L../../../binaries/linux/x86_64 -lultimate_alpr-sdk -o recognizer

This is output which I am getting :

You need libtensorflow.so -> https://github.com/DoubangoTelecom/ultimateALPR-SDK/blob/master/samples/c%2B%2B/README.md#gpu-acceleration-tensorflow-linux

After following https://github.com/DoubangoTelecom/ultimateALPR-SDK/blob/master/samples/c%2B%2B/README.md#gpu-acceleration-tensorflow-linux, the problem is still existing. Any suggestion?

Link to tensorflow library -ltensorflow

[mochechan]

Link to tensorflow library -ltensorflow

Success. Thank you.

Additional question: How to setup CMakeLists.txt rather than using g++ directly?
The CMakeLists.txt in ultimateALPR-SDK/samples/c++/recognizer/ has some problems.

The CMakeLists.txt in ultimateALPR-SDK/samples/c++/recognizer/ has some problems.

These CMake files have dependencies on private code. We think it's useless to create one for a single file. If you still want one use https://github.com/DoubangoTelecom/FaceLivenessDetection-SDK/blob/master/samples/cpp/liveness/CMakeLists.txt.:
Some changes:

• project (liveness VERSION 1.0.0 LANGUAGES CXX C) -> project (recognizer VERSION 1.0.0 LANGUAGES CXX C)
• ${CMAKE_CURRENT_SOURCE_DIR}/../../../cpp -> ${CMAKE_CURRENT_SOURCE_DIR}/../../../c++
• libFaceLivenessDetectionSDK.so -> libultimate_alpr-sdk.so
• set (SOURCE liveness.cxx) -> set (SOURCE recognizer.cxx)
• and add libtensorflow to target_link_libraries(...)
  ... haven't tested but I think that's it.
