rocksdb::CreateIOUring() undefined references

[2ico]

Expected: Successful build of the ton toolchain.

Actual behavior:

$ sudo ldconfig -v | grep uring
liburing.so.2 -> liburing.so.2.2

To reproduce: cmake --build . --target fift Follow the steps on https://ton.org/docs/#/compile?id=how-to-compile

Version: Self-compiled from tesnet branch. I've also tried master and the SpyCheese fork.

This operating system looks interesting 0.0 https://manjaro.org/

Looks like a kind of Arch Linux Maybe you can try to install these dependencies

pacman -S --noconfirm git make cmake clang gflags zlib openssl readline libmicrohttpd python python-pip

I got the exact same issue on Arch Linux, the issue is that the uring library is not being linked. Didn't look at the code so I'm not sure why this is an issue on Arch and not on Ubuntu, but the following patch fixes the issue for fift specifically:

--- a/crypto/CMakeLists.txt
+++ b/crypto/CMakeLists.txt
@@ -294,7 +294,7 @@ target_link_libraries(fift-lib PUBLIC ton_crypto ton_db tdutils ton_block)

 if (WINGETOPT_FOUND)
   target_link_libraries_system(fift wingetopt)
 endif()

That being said, there's many targets that fail to build without uring, and also a few that require gsl and gslcblas. I can share a PR that fixes all the targets on Arch if that's desirable, and someone who's more familiar with the code could then take a look at what's going on.
