PIP INSTALLATION STILL FAIL

[NoCodeAvaible]

Hey dear contributors,
the pip installation still fails to install ctcdecode on windows.
I've tried to do:
git clone --recursive https://github.com/parlance/ctcdecode.git
cd ctcdecode && pip install .

but nothing seems to work.
This is the error being raiced while trying to install the module:

It would be very very nice if this could be fixed.
Thank's for every help in advance;)

hello all,

after spending a certain amount of time i found the problem. in my case, the development packages of python (python-dev and python3-dev) were not installed. after installing them on Ubuntu-18.04 using: sudo apt install python-dev && sudo apt install python3-dev, i was able to install ctcdecode without a problem.

however, this may not be the exact case for you so i recommend you to check whether you have the following packages/libraries (also giving the versions i am using):

1. essential packages for building debian packages: sudo apt install build-essential
2. torch==1.9.0
3. gcc and g++ version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)

hope these help!

Same problem here on MB Pro M1, I tried to pip install . but didn't work even after many times trying to install the third_party dependencies (Boost, OpenFst) with several different versions. I think the problem was on the g++ compiler. Any idea to resolve this?
