Youcompleteme: CMake Error at ycm/CMakeLists file DOWNLOAD HASH mismatch

Created on 2 Oct 2015 · 15Comments · Source: ycm-core/YouCompleteMe

I install youcompleteme with some problems. My system is ubuntu 14.04, as I went to the last step
./install.py --clang-completer there would be error as follow. I tried many times, the problems were all the same. Looking forward to your help, thx a lot.

This command can fix the problem

./install.py --clang-completer --system-libclang

The issue is that CMake does not complete the Clang download.

As I explained in issue #1640, you can directly download the Clang archive here and move it in the ~/.vim/bundle/YouCompleteMe/third_party/ycmd/clang_archives folder. Once this is done, run again the script install.py.

Clang link provided (at present time) returns 503:

http://llvm.org/releases/3.7.0/clang+llvm-3.7.0-x86_64-linux-gnu-ubuntu-14.04.tar.xz

Error 503 first byte timeout

The Clang binaries have been moved to https://releases.llvm.org.

also, why would you want to download clang 3.7.0 ? ycmd currently uses 5.0.1

I downloaded the Clang archive and moved it to ~/.vim/bundle/YouCompleteMe/third_party/ycmd/clang_archives folder. Now, I have the tar.xz file there. But upon running the script install.py, it starts downloading the whole thing again. How to go about now?
