Thanks for your report. This is reproduced on the Docker container. Please upgrade to Ubuntu 22.04 or install in a container. |

Installing one of the GH release builds should still work on 20.04, though right? install.packages(
"https://github.com/pola-rs/r-polars/releases/latest/download/polars__x86_64-pc-linux-gnu.gz",
repos = NULL
) |
To clarify, is it R-universe that doesn't support Ubuntu 20.04, or something else? |
|
R-universe is irrelevant. |

Hi all, I know very little about the specifics of polars setup/compilation here... so take what follows with a grain of salt. I believe Ubuntu 20.04 uses an older version of GLIBC... I have seen this cause issues with Rust-based tools used on 20.04 if they were compiled using e.g. the GLIBC version included with 22.04 |
From what I understand, #514 (comment)'s logs is from a complete source installation, so this is a different issue. |
It seems fail to load due to the GLIBC version. Details
I'm not sure if failing to build and failing to load are the same issue. |
|
Therefore make sense to mention minimal supported version of Ubuntu, and ideally Debian as well. |
|
We actually don't know why Cargo fails to build the binary, so we can't say for sure. |

It seems that librt, the real-time library, where shm_unlink and others are from, may be found during linking, but not during runtime? I got successful installation in Ubuntu 20.04 docker container by adding diff --git a/src/Makevars.in b/src/Makevars.in

@brownag Thank you for digging that! r-polars/.github/workflows/release-lib.yaml Lines 37 to 40 in 11af69c Re the musl targets, I tried but the unit tests about background execution (?) are failed (Sorry I missed the log and the PR number...) |
