There is this code in Makefile.system:

ifeq ($(shell [ $(XCVER) -ge 16 ] && echo yes),yes)
override CEXTRALIB := $(filter-out(-lto_library, $(CEXTRALIB)))
endif

Seems like this check doesn't work for you? I see discussion mentioning
that the XCVER could be empty. Maybe this should be turned into opt-in
… or just unconditionally filter-out.

Adam, can you test this?

The full block:

ifeq ($(OSNAME), Darwin)
ifndef MACOSX_DEPLOYMENT_TARGET
ifeq ($(ARCH), arm64)
export MACOSX_DEPLOYMENT_TARGET=11.0
export NO_SVE = 1
# export NO_SME = 1
else
export MACOSX_DEPLOYMENT_TARGET=10.8
endif
endif
MD5SUM = md5 -r
XCVER = $(shell pkgutil --pkg-info=com.apple.pkg.Xcode |awk '/version:/ {print $2}'|cut -d: -f2|cut -f1 -d.)
ifeq (x$(XCVER)x,xx)
XCVER = $(shell pkgutil --pkg-info=com.apple.pkg.CLTools_Executables |awk '/version:/ {print $2}'|cut -d: -f2|cut -f1 -d.)
endif
ifeq (x$(XCVER), x 15)
CCOMMON_OPT += -Wl,-ld_classic
FCOMMON_OPT += -Wl,-ld_classic
endif
ifeq ($(shell [ $(XCVER) -ge 16 ] && echo yes),yes)
override CEXTRALIB := $(filter-out(-lto_library, $(CEXTRALIB)))
endif
endif


I guess we want it to read

ifeq ($(OSNAME), Darwin)
ifndef MACOSX_DEPLOYMENT_TARGET
ifeq ($(ARCH), arm64)
export MACOSX_DEPLOYMENT_TARGET=11.0
export NO_SVE = 1
# export NO_SME = 1
else
export MACOSX_DEPLOYMENT_TARGET=10.8
endif
endif
MD5SUM = md5 -r
XCVER = $(shell pkgutil --pkg-info=com.apple.pkg.Xcode |awk '/version:/ {print $2}'|cut -d: -f2|cut -f1 -d.)
ifeq (x$(XCVER)x,xx)
XCVER = $(shell pkgutil --pkg-info=com.apple.pkg.CLTools_Executables |awk '/version:/ {print $2}'|cut -d: -f2|cut -f1 -d.)
endif
ifeq (x$(XCVER), x 15)
CCOMMON_OPT += -Wl,-ld_classic
FCOMMON_OPT += -Wl,-ld_classic
endif
# Always remove troublesome LTO linking option.
#ifeq ($(shell [ $(XCVER) -ge 16 ] && echo yes),yes)
override CEXTRALIB := $(filter-out(-lto_library, $(CEXTRALIB)))
#endif
endif


But maybe you can figure out a better check and submit that upstream.


Alrighty then,

Thomas
