Blocks, and lambdas, and clang... oh my.

The Block type extention introduced by Apple seems to be broken, buggy, and all around horrible. Can we exploit it?

You need CMake >= 3.15

Linux

sudo apt-get install llvm
sudo apt-get install clang
sudo apt-get install libblocksruntime-dev

cmake -D CMAKE_CXX_COMPILER=clang++ ..
cmake --build .

MacOS

cmake ..
cmake --build .

Windows:

Build the llvm-project (and clang along with it):

https://clang.llvm.org/get_started.html

cd blockhead/cpp

Run...

clang++ -fblocks main.cpp -o blockhead_cpp.exe

Puzzle over why it will not link.
