Compilation error on GCC 7.4 / Ubuntu 18.04 #127

Open vadimkantorov opened 4 years ago

I have PyTorch installed from a nightly build. I think maybe it now needs a C++14 options in compiler.

I install ctcdecode as pip install git+https://github.com/parlance/ctcdecode

export CFLAGS=-std=c++14 didn't help

Probably https://github.com/parlance/ctcdecode/blob/master/build.py#L44 is problematic and needs to be updated to c++14

vadimkantorov commented 4 years ago

Confirmed, this is the cause. sed -i 's/11/14/g' build.py fixes the problem

When I installing ctcdecode, it shows building wheels and then my system hangs..it does not complete installation..anyone please give your suggestion. I am stucked here for a week
