Build error: undefined reference to `io_uring_queue_init'

[kazei92]

While I am building using Cmake according to https://github.com/ton-blockchain/ton/tree/master/tonlib

cd <path to Ton sources>
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=../example/cpp/tonlib ..
cmake --build . --target install

Building process stops at:

Could you please help me to fix it?

Have you managed to solve the issue? Which compilator are you using?

[kazei92]

I haven't, but as I need only tonlib - I have compiled with the -DTON_ONLY_TONLIB=ON and it worked.

I still have the same issue. Why is it completed?

[XiaoChenQAQ]

add -luring in the end, like: g++ main.cpp -luring.
