I'm a little stumped on this one, as I move from Ubuntu to
Debian 9.4 for my build box.
Right now, looks like SetupHostCommand isn't robust enough.
Destroying staging_dir/ and re-running make menuconfig was required.
jeff@deb-devel:~/devel/openwrt$ make V=s
make[1] clean
time: invalid option -- 'f'
BusyBox v1.22.1 (Debian 1:1.22.0-19+b3) multi-call binary.
Usage: time [-v] PROG ARGS
Run PROG, display resource usage when it exits
-v Verbose
target/Makefile:23: recipe for target 'target/linux/prereq' failed
[...]
I've already installed the Debian package for time
jeff@deb-devel:~/devel/openwrt$ dpkg -L time
/.
/usr
/usr/bin
/usr/bin/time
[...]
jeff@deb-devel:~/devel/openwrt$ which time
/usr/bin/time
yet, for some reason, the build system is picking up busybox which is not symlinked from time anywhere that I can find
jeff@deb-devel:~/devel/openwrt$ sudo find / -xdev -name time
/usr/bin/time
/usr/src/linux-headers-4.9.0-6-amd64/include/config/generic/time
/usr/src/linux-headers-4.9.0-6-amd64/include/config/have/irq/time
/usr/share/doc-base/time
/usr/share/doc/time
jeff@deb-devel:~/devel/openwrt$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
Very fresh Debian "minimal" debootstrap install with updated with tasksel install standard (which is still pretty barebones) and htop, git, gitk, git-gui, rsync, ccache, build-essential, libncurses5-dev gawk unzip time
Edit:
$(eval $(call SetupHostCommand,time,Please install GNU 'time' or BusyBox 'time', \
gtime --version 2>&1 | grep GNU, \
time --version 2>&1 | grep GNU, \
busybox time 2>&1 | grep BusyBox))
include/subdir.mk: env time -f "time: $(1)$(if $(4),/$(4))/$(if $(3),$(3)-)$(2)\#%U\#%S\#%e" -- \
jeff@deb-devel:~/devel/openwrt$ env time -V
GNU time 1.7
time alone is a reserved word in bash, not an executable, but that doesn't explain why the build system had decided to call busybox.
jeff@deb-devel:~/devel/openwrt$ ls -l staging_dir/host/bin/
