llvm dev - Mar 2021 - Compiling Kaleidoscope with clang++

Dear all,

As I am trying to run Kaleidoscope code from https://llvm.org, I am
receiving following error message.

Error : no template named 'make_unique' in namespace 'std' ; did
you simply
mean 'make_unique' ?


Please advise. Note that I have seen a solution with cmake in some website.
As I am not very familiar with cmake, kindly elaborate the usage more in
case your solution has cmake.

Thanks.

Hi Sudakshina ,

It sounds like you are compiling in C++11 mode. LLVM has recently 
switched to C++14. make_unique is one of the features introduced in C++14.

Could you try making sure that you use C++14? Here's how you set it up 
in CMake

```
set(CMAKE_CXX_STANDARD 14 CACHE STRING "")
```

I hope that this helps,
Andrzej
