Description Ed Maste freebsd_committer 2018-03-27 16:11:56 UTC
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 the exp-run, PR 214864.

An excerpt from the build log[2]:
---
cc -O2 -pipe  -fstack-protector -fno-strict-aliasing -c string-lib.c -o string-lib.o
ld: error: -O: number expected, but got 'string-lib.o'
*** Error code 1
---

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=yes, 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.

A commit references this bug:

Author: emaste
Date: Tue Mar 27 20:46:44 UTC 2018
New revision: 465749
URL: https://svnweb.freebsd.org/changeset/ports/465749

Log:
  www/cgihtml: set LLD_UNSAFE

  This port passes an unusual option to the linker that is accepted by
  ld.bfd but rejected by ld.lld.  Linking with lld fails with:

  ld: error: -O: number expected, but got 'string-lib.o'
