Revision: 438141
Last Changed Rev: 438141
I was trying to build synth on an arm64 (BPI-M3) and it in turn tried
to build gcc6-aux. That failed with:
checking for autoheader... no
configure: updating cache ./config.cache
configure: creating ./config.status
config.status: creating Makefile
config.status: creating config.intl
config.status: creating config.h
config.status: executing default-1 commands
gmake[3]: Leaving directory
'/usr/obj/portswork/usr/ports/lang/gcc6-aux/work/build'
gmake[2]: *** [Makefile:875: all] Error 2
gmake[2]: Leaving directory
'/usr/obj/portswork/usr/ports/lang/gcc6-aux/work/build'
*** Error code 2
Looking around in:
/usr/obj/portswork/usr/ports/lang/gcc6-aux/work/build/Makefile
shows. . .
SHELL = /bin/sh
# pwd command to use. Allow user to override default by setting PWDCMD in
# the environment to account for automounters. The make variable must not
# be called PWDCMD, otherwise the value set here is passed to make
# subprocesses and overrides the setting from the user's environment.
# Don't use PWD since it is a common shell environment variable and we
# don't want to corrupt it.
PWD_COMMAND = $${PWDCMD-pwd}
. . .
# The target built for a native non-bootstrap build.
.PHONY: all
all:
@: $(MAKE); $(unstage)
@r=`${PWD_COMMAND}`; export r; \
s=`cd $(srcdir); ${PWD_COMMAND}`; export s; \
$(MAKE) $(RECURSE_FLAGS_TO_PASS) all-host all-target \
&& :
with line 875 being the one with: @r=`${PWD_COMMAND}`
It appears to me that the notation $${PWDCMD-pwd} is not
what was intended. My guess is that a ":" is missing:
PWD_COMMAND = $${PWDCMD:-pwd}
(/bin/sh notation to avoid an empty PWDCMD by then using pwd).
NOTE on arm64 and fork() behavior:
head (12) has received 2 fixes to arm64 fork behavior in recent times:
-r316679
-r313772
stable/11 is supposed to get an MFC for -r316679 in a couple
of weeks.
-r313772 was from February and has yet to be MFC'd but is needed.
No explicit MFC schedule has been set.
