Subject: Re: [PATCH v3 4/4] objtool: Add explicitly sequenced -lzstd to libopcodes fallback
Date: Wed, 04 Nov 2026 04:32:53 +0000 [thread overview]
Message-ID: <sashiko-outbox-196654@kernel.org> (raw)
In-Reply-To: <20261104043006.1199857-5-irogers@google.com>
> Distributions like Fedora ship a statically compiled binutils libbfd (an
> intrinsic dependency of libopcodes) that uses zstd to decompress
> sections.
>
> Because objtool resolves host dependencies sequentially via a manual
> HOSTCC shell loop, linking against static binutils fails with undefined
> references to 'ZSTD_decompress' unless the loop probes for -lzstd.
>
> Add the '-lopcodes -lbfd -liberty -lz -lzstd' combination to the
> LIBOPCODES_LIBS fallback chain.
