Additional

As the liburing files were not present initially, i had to install them using yay -S liburing

Can you try to install from github? This issue should be fixed!

hmm... liburing files were included in pip install liburing build.

Update: worked with pip install git+https://github.com/YoSTEALTH/Liburing Thanks.

[YoSTEALTH]

ok, cool ... https://github.com/YoSTEALTH/Liburing/tree/master/libs uses submodules so ya... :)

[govardhangdg]

But I can't use it :(

hmm... that is weird. how did it install without compiling the liburing._liburing.so?

[YoSTEALTH]

can you try pip install --upgrade way? maybe you are looking at previously failed installed.

[govardhangdg]

It worked! Thanks a lot!!

[YoSTEALTH]

cool :)
