build error missing time.o for 2.2 (no error 2.1)

Expected behavior

Build

Actual behavior

I have been making builds with 2.1 for the past year without any issues. I created a new disk for 2.2 but when I attempt to build from 2.2 I get this error:

ar d /Volumes/casesenshfs-220/nodemcu-firmware/sdk/esp_iot_sdk_v2.2.0-f8f27ce/lib/libmain.a time.o
ar: time.o: not found in archive

Here is what I use to build:
git clone --recursive https://github.com/pfalcon/esp-open-sdk.git
cd esp-open-sdk
make STANDALONE=y
export PATH=...
cd ..
git clone https://github.com/nodemcu/nodemcu-firmware.git
cd nodemcu-firmware
make clean
make

@stevemac00 I am doing these sdk_v2.2.0-f8f27ce builds regularly and my build doesn't attempt to access time.o

~~I can't find anything in the makefile to attempt to delete time.o from libmain.a. Can you post the make log as a gist and link it here. Thanks.~

Found it. It's generated in the root Makefile rule sdk_pruned. These sdk rules have side effects and so aren't intended to be interrupted. Did you abort a make just after starting? Just remove the sdk folder under your root (/Volumes/casesenshfs-220/nodemcu-firmware/sdk in your case) and the make will recreate it properly.

[stevemac00]

I may have aborted at one time (I put this away for awhile and can't remember).
I did rm -rf /Volumes/casesenshfs-220/nodemcu-firmware/sdk/ but still got the same error.
The gist is https://gist.github.com/stevemac00/059ec9109f9865132ddcda70925bf8ee

Since it's complaining about time.o, my only clue is I'm defining SNTP but not RTCTIME although that was fine in 2.1.

@stevemac00 building from master also works for me.
What is the output when you list the archive manually once the build failed?
For me it's

$ ar t sdk/esp_iot_sdk_v2.2.0-f8f27ce/lib/libmain.a
app_main.o
eagle_lib.o
eagle_lwip_if.o
ets_timer.o
mem_manager.o
spi_overlap.o
time.o
user_interface.o
debug-vector.o
double-vector.o
kernel-vector.o
nmi-vector.o
user-vector.o
vector.o
spi_flash.o
$ ar --version
GNU ar (GNU Binutils; openSUSE Leap 42.3) 2.29.1

Deleting time.o is going to succeed of course.

[stevemac00]

$ ar t sdk/esp_iot_sdk_v2.2.0-f8f27ce/lib/libmain.a

/
//
app_main.o/
eagle_lib.o/
eagle_lwip_if.o/
ets_timer.o/
mem_manager.o/
spi_overlap.o/
time.o/
/0
debug-vector.o/
double-vector.o/
kernel-vector.o/
nmi-vector.o/
user-vector.o/
vector.o/
spi_flash.o/

Now I'm even more confused. What is that /0 after time.o ?

Strange indeed. It's in the row where I have user_interface.o.
Is there anything else when you list verbosely with ar tv?
Which version of ar / binutils is this?

[stevemac00]

Thanks for staying on this as I need the help. Something is wrong with what I've used on the 220 but I list the simple instructions I followed on my original post at the top.

I'm on MacOS 10.13.6 and using /usr/bin/ar included but it doesn't support the 'V' option for version.
I have my 2.1 and 2.2 builds on separate images so I went back to 2.1 and did a make clean then make which worked fine although it lists the same '/0'.

I'm wondering why the date is older on -220 than it is on -210?

Found a solution!
Turns out the 2.1 build has:
esp-open-sdk/xtensa-lx106-elf/bin/ar
where as the 2.2 build does not but has:
esp-open-sdk/xtensa-lx106-elf/bin/xtensa-lx106-elf-ar

I simply cp xtensa-lx106-elf-ar to ar so it was used in my $PATH before /usr/bin/ar and it worked. Maybe the make file could be updated to explicitly use xtensa-lx106-elf-ar?

[devsaurus]

Sure, that should do the trick 👍 Also removes dependencies to the host system installation.
Thanks a lot for digging this up!
