From 4593b142d5d0dc7c8ef369e2a42e9a4c805b8a51 Mon Sep 17 00:00:00 2001 From: Justin Bronder Date: Mon, 16 Dec 2024 14:51:32 -0500 Subject: [PATCH] scripts: wrap lz4c and convert to lz4 Commit fe167e082cbde1c6d186ecdda531abef610ac2ac switched to requiring lz4 instead of lz4c which allows us to support distros dropping lz4c. However, it wasn't only OE that was still using the legacy lz4c, there's a number of upstreams as well. For instance, it's only in the 6.13 kernel that CONFIG_KERNEL_LZ4 makes the switch from lz4c to lz4. So, while this all gets ironed out, simply intercept calls to lz4c and convert them to use lz4. This was picked instead of adding lz4c to HOSTTOOLS_NONFATAL due to concerns about builds becoming non-deterministic and failing late: https://lore.kernel.org/openembedded-core/9c3143ebb7f9e17cfbd318ef0e17994aae7264be.camel@linuxfoundation.org/ (From OE-Core rev: c10b94d82d10058a9e26f7d6919a0d6d721a7c75) Signed-off-by: Justin Bronder Signed-off-by: Richard Purdie --- scripts/lz4c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100755 scripts/lz4c diff --git a/scripts/lz4c b/scripts/lz4c new file mode 100755 index 0000000000..466fc349e0 --- /dev/null +++ b/scripts/lz4c @@ -0,0 +1,26 @@ +#!/usr/bin/env bash + +# Wrapper to intercept legacy lz4c arguments and convert to lz4. +args=() +while [ $# -ne 0 ]; do + case ${1} in + -c0) + args+=(-0) + ;; + -c1) + args+=(-9) + ;; + -c2|-hc) + args+=(-12) + ;; + -y) + args+=(--force) + ;; + *) + args+=("${1}") + ;; + esac + shift +done + +exec lz4 "${args[@]}"
