libc version incompatibility about bpftop HOT 4 CLOSED

I am not familiar with the amazon linux images, but it seems that they are either using an old version of glibc or using musl.

1. find out the version you have : ldd --version | grep -i 'glibc'
2. if the version is older than 2.29 then you need to build bpftop from source.
   (you do have the same problem with cross as it's built with a newer version of glibc than the one you might have, so cargo install cross --git https://github.com/cross-rs/cross might work as it will build cross from sources.)

Yes, you just need to build it from the source. You don't actually need cross if you are building it on your target host. Just run cargo build --release.

Thanks for the replies. Managed to get it working 🥳
Built it from the source, just needed to re-install cargo with rustup. I've installed with yum package manager beforehand. It seemed rustc version was outdated.

 $ cargo build --release
error: package `ratatui v0.26.1` cannot be built because it requires rustc 1.70.0 or newer, while the currently active rustc version is 1.68.2
Either upgrade to rustc 1.70.0 or newer, or use
cargo update -p [email protected] --precise ver
where `ver` is the latest version of `ratatui` supporting rustc 1.68.2

$ rustc -V
rustc 1.68.2 (9eb3afe9e 2023-03-27) (Amazon Linux 1.68.2-1.amzn2.0.4)

$ cargo -V
cargo 1.68.2

After updating rustc version by installing with rustup, it worked fine.
curl https://sh.rustup.rs/ -sSf | sh

$ rustc -V
rustc 1.76.0 (07dca489a 2024-02-04)

$ cargo -V
cargo 1.76.0 (c84b36747 2024-01-18)

from bpftop.

Glad it worked out!
