Description Ed Maste freebsd_committer 2017-08-25 13:00:02 UTC
I've been investigating the state of the ports tree with LLVM's lld installed as /usr/bin/ld (from the exp-run in PR 214864).

Normally LDFLAGS contains flags passed to the compiler driver when invoked for linking. One issue that affects a small number of ports is passing $LDFLAGS to direct linker invocation (i.e, $LD), where it contains flags that are appropriate only for the compiler driver, not the linker.

In several instances this comes from bsd.ssp.mk, which adds -fstack-protector to LDFLAGS.  GNU BFD ld accepts the flag but produces undesired output, while lld produces an error:

ld -fstack-protector -shared -o libcfg+.so.0 ../src/cfg+.o ../src/parse.o ../src/props.o ../src/cmdline.o ../src/cfgfile.o ../src/shared.o ../src/platon/str/strplus.o ../src/platon/str/strctype.o ../src/platon/str/strdyn.o ../src/platon/str/dynfgets.o
ld: error: unknown argument: -fstack-protector
(from devel/libcfg)

(GNU ld produces output with a bogus DT_AUXILIARY "stack-protector" entry for this case.)

This affects at least the following ports:

I no longer use this port so can't maintain it, and to be honest I expect it's been superseded by better ways to do the same task so I suggest deleting the port.
