Detecting native triple on RHEL 9.0 and Fedora 36 gives wrong result #12156

songdongsheng · 2022-07-18T04:00:20Z

Zig Version

0.10.0-dev.3027+0e26c6149

Steps to Reproduce

podman run --rm -it registry.access.redhat.com/ubi9

dnf install -y bsdtar gcc-c++ jq && rpm -qa | grep -E "binutils|kernel-headers|glibc-devel|gcc-c++"
export PATH=/opt/zig:/usr/sbin:/usr/bin:/sbin:/bin

$ zig version
0.10.0-dev.3027+0e26c6149

zig targets | jq -r '.native.triple'

x86_64-linux.5.10.16...5.10.16-musl

Expected Behavior

zig targets | jq -r '.native.triple'

x86_64-linux.5.10.16...5.10.16-gnu.2.34

Actual Behavior

zig targets | jq -r '.native.triple'

x86_64-linux.5.10.16...5.10.16-musl

RHEL 9 is glibc distributions, not musl !

Fedora 36 give wrong glibc version 2.19 instead of the correct version 2.35 !

$ podman run --rm -it quay.io/fedora/fedora:36

$ dnf install -y bsdtar gcc-c++ jq

$ rpm -qa | grep -E "binutils|kernel-headers|glibc-devel|gcc-c++"

$ zig targets | jq -r '.native.triple'
x86_64-linux.5.18...5.18-gnu.2.19

It should be x86_64-linux.5.18...5.18-gnu.2.35, not x86_64-linux.5.18...5.18-gnu.2.19 !

Are you using static build from https://ziglang.org/download ? If so, can you please share output of file /usr/bin/env and file /bin/bash

BratishkaErik · 2022-07-18T10:36:04Z

Well, according to https://catalog.redhat.com/software/containers/ubi9/ubi/615bcf606feffc5384e8452e?container-tabs=packages your Red Hat Universal Base Image 9 installs coreutils-single package, not coreutils, so #12151 will fix this

BratishkaErik · 2022-08-22T00:47:36Z

And now this is a duplicate of #6469

songdongsheng · 2022-10-17T05:05:34Z

No.

fedora 36 reports x86_64-linux.5.19...5.19-gnu.2.35, this is correct.

But UBI9 (RHEL 9) still report x86_64-linux.5.19...5.19-musl:

My suggestion — something to do with this?

the waning message is linked to :

zig/lib/std/zig/system/NativeTargetInfo.zig

Line 339 in d3b1cdf

    
           std.log.warn("Encountered error: {s}, falling back to default ABI and dynamic linker.\n", .{@errorName(e)});

searching for "/usr/bin/env"
this is why my project compilation goes to fallback in the nix environment, but works on my pc (the env file exists)

frett27 · 2022-12-14T19:05:51Z

@BratishkaErik do you have the /usr/bin/env on your system ?

If it helps anyone: King and I were able to work around this by checking if I'm building on RHEL and if so, link against glibc rather than musl. (Zig 0.9.1).

# Zig picks musl libc instead of glibc, incorrectly                                                                                                                                          
# https://github.com/ziglang/zig/issues/12156                                                                                                                                                
if [ -f "/etc/redhat-release" ]; then
    target="-target native-native-gnu"
fi

432: No target on linux, except RHEL r=sentientwaffle a=eatonphil `zig targets` doesn't seem to produce a target that can be safely fed back into `zig build -target X`. Or at least not in a way I can find. So rather than even trying, we'll just completely omit `-target X` like we used to do. And we'll only override the target in the macOS case. And also RHEL given ziglang/zig#12156. Closes #433 Co-authored-by: Phil Eaton <[email protected]>
