$ grep RUSTC .config CONFIG_RUSTC_VERSION=0 CONFIG_RUSTC_LLVM_VERSION=0 if i add RUSTC=false it compiles, i.e. $ make RUSTC=false LLVM=-20 -- that will succeed without error rustc-llvm-version.sh contains
# Convert the version string x.y.z to a canonical up-to-6-digits form.
get_canonical_version()
{
IFS=.
set -- $1
echo $((10000 * $1 + 100 * $2 + $3))
}
but i have rustc version 10.0 nightly
$ rustc --version --verbose | grep LLVM
LLVM version: 10.0
$ rustc --version --verbose
rustc 1.47.0-nightly (6c8927b0c 2020-07-26)
binary: rustc
commit-hash: 6c8927b0cf80ceee19386026cf9d7fd4fd9d486f
commit-date: 2020-07-26
host: x86_64-unknown-linux-gnu
release: 1.47.0-nightly
LLVM version: 10.0
so the script expects version x.y.z when the nightly version is x.y
Thanks for the report (and Thorsten for mentioning it to us), confirmed! Fix submitted at https://lore.kernel.org/rust-for-linux/20241027145636.416030-1-ojeda@kernel.org/ It would be great if you can confirm it fixes it for you -- thanks!
