jan kili (Sep 16 2022 at 22:32): jan kili (Sep 16 2022 at 22:32):I'm trying to build the Roc CLI & an application from source in a Debian-based Docker container, and I'm having some glibc-related issues. In my attempts to either use the nightly build or compile the Roc CLI from source, I've inevitably ended up with some variation of not having a recent-enough version of glibc installed. Now I'm trying a simpler setup with a clean debian image, and I'm getting something close but different. Any ideas?
My steps:
docker pull debian:bullseye
docker run -it debian:bullseye
apt-get update
apt-get install -y build-essential curl git wasi-libc
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
export PATH="/root/.cargo/bin:${PATH}"
git clone https://github.com/roc-lang/roc
cd roc
cargo build --release
Output of retrying the last step:

Oh, Zig is a requirement for building the Roc CLI, isn't it?
Richard Feldman (Sep 17 2022 at 02:10):yeah, it's required for building the Roc standard library, so definitely required for building the CLI! :big_smile:
jan kili (Sep 17 2022 at 02:11):Alright! Anything else I forgot? Various common linux utilities, Rust, Zig...
Brendan Hansknecht (Sep 17 2022 at 03:12):You can always look at the earth file or the nix flake file
Brendan Hansknecht (Sep 17 2022 at 03:12):Both should give a list
Brendan Hansknecht (Sep 17 2022 at 03:12):The earth file would read like a docker file with install commands
jan kili (Sep 17 2022 at 03:19):Ooh! Good point, thanks
jan kili (Sep 17 2022 at 04:32):Well, darn, that worked too well. Copying the Earthfile steps into my Dockerfile made the next build work exactly as intended, so instead of playing music or browsing the web or responding to my mouse movements my laptop is now JUST compiling the Roc CLI inside of Docker :laughing:
jan kili (Sep 17 2022 at 04:55):The CLI built! However, the app didn't, and this is interesting: version 'GLIBC_2.34' not found (required by /app/roc/examples/interactive/cli-platform/target/debug/build/host-ada94793d07cf987/build-script-build)

Debian bullseye comes with glibc v2.31 installed, and I can't find how to upgrade that (since compiling examples/interactive/cli-platform needs v2.34, apparently). How can someone compile Roc apps (for example, using examples/interactive/cli-platform/ as the platform) on a stable release of Debian?
jan kili (Sep 17 2022 at 06:49):I'm trying debian:testing now, as it has glibc v2.34 ...
jan kili (Sep 17 2022 at 06:52):I know that Debian's long release cycle might conflict with Roc's pre-alpha nature, but stable OS distributions make for very good servers.
jan kili (Sep 17 2022 at 07:10):debian:testing built the app! :D
Brendan Hansknecht (Sep 17 2022 at 16:09):Roc never dictates the glibc version. Do the question is how is the platform or linker pulling in that version of glibc?
jan kili (Sep 17 2022 at 21:25):Rust libc dependency in the build.rs - should that change?
Brendan Hansknecht (Sep 17 2022 at 21:46):Maybe? I thought that just grabbed the system libc. But it is likely grabbing the wrong thing and causing your issue?
jan kili (Sep 17 2022 at 21:57):I believe so
jan kili (Sep 17 2022 at 21:58):Though that doesn't totally make sense to me
jan kili (Sep 17 2022 at 21:58):Though libc in general doesn't totally make sense to me :sweat_smile:
