Wav2letter: failing : cmake .. -DCMAKE_BUILD_TYPE=Release -DW2L_CRITERION_BACKEND=CUDA . cannot find CharLMDecoder.cpp

[megharangaswamy]

I am trying to do decoder stage and I ended up with segmentation fault. when I checked a few issues related to that, it was suggested to take the latest version of wav2letter++ because a few new things were fixed in the latest code. But when I am making

cmake .. -DCMAKE_BUILD_TYPE=Release -DW2L_CRITERION_BACKEND=CUDA

I am getting below error.

As the error tells, I am not able to find any file called CharLMDecoder.cpp inside src/decoder. Kindly help me with this. I see a few new check-ins in the code related to CharLM. And I found
WordLMDecoder.cpp inside decoder folder but not CharLMDecoder.cpp. I am not sure if I am thinking it right. Kindly help me to solve this.
@xuqiantong, can you confirm if I need to change anything here?

Thanks,
Megha
