https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D226997 Bug ID: 226997 Summary: sysutils/dupd: fails to link with lld as the system linker Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: emaste@freebsd.org CC: tom@hur.st Blocks: 214864 CC: tom@hur.st Flags: maintainer-feedback?(tom@hur.st) I'm working on switching to LLVM's lld linker as the FreeBSD system linker (/usr/bin/ld)[1], and the port in this PR is reported as a new failure in t= he exp-run, PR 214864. An excerpt from the build log[2]: --- ld -r -b binary -o /wrkdirs/usr/ports/sysutils/dupd/work/dupd-1.4/build/usa= ge.o man/dupd ld: error: target emulation unknown: -m or at least one .o file required--- Known issues in this port or in lld that affect this port: (4) lld does not have a built-in default output target. For the most common= use of the linker (linking individual .o objects into an executable or shared object) lld infers the target from the first object file. However, when the linker is used to convert an arbitrary binary file into an ELF object (via = -r -b binary) lld must have the output target specified explicitly with -m. FreeBSD 11 and later have lld available as /usr/bin/ld.lld, so one simple option for testing is to just symlink /usr/bin/ld to ld.lld (and restore it= to ld.bfd). A port Makefile knob, LLD_UNSAFE=3Dyes, exists to indicate that a port does= not work with lld, and requires either /usr/bin/ld.bfd or binutils from ports. = This should work for the common case of ports written in C using GNU autoconf; it may have no effect on other ports.
