Bug ID: 113499
Summary: crab1 fails to link when configuring with
--disable-plugin
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rust
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
CC: dkm at gcc dot gnu.org, gcc-rust at gcc dot gnu.org
Target Milestone: ---
With --disable-plugin we probably elide -ldl but crab1 calls dlopen even when
plugin support is disabled leading to
