Describe the Bug

I used "qmk compile" for ergodox_stm32, there was such error prompt:

Additional Context

[drashna]

Compiles fine for me. You're probably missing submodules.

Run make git-submodule from the qmk_firmware directory and recompile.

[mianqi2016]

Since the net was too slow, so I download .zip from qmk@github, while:

`qmk compile -kb ergodox_stm32 -km default
Ψ Compiling keymap with make --jobs=1 ergodox_stm32:default

⚠ "git describe --abbrev=6 --dirty --always --tags" returned error code 128
Makefile:507: *** multiple target patterns. Stop.
`

make git-submodule make: *** No rule to make target 'git-submodule'. Stop.

[fauxpark]

Downloading the zip file from GitHub won't work, you need to follow the setup instructions.

[mianqi2016]

Now, there is a new error:
Linking: .build/ergodox_stm32_default.elf [ERRORS] | | arm-none-eabi-gcc: error: .build/obj_ergodox_stm32_default/lib/printf/printf.o: No such file or directory | make[1]: *** [tmk_core/rules.mk:365: .build/ergodox_stm32_default.elf] Error 1 Make finished with errors

I tested crkbd, it was OK, so qmk work correctly:
`Linking: .build/crkbd_rev1_default.elf [OK]
Creating load file for flashing: .build/crkbd_rev1_default.hex [OK]
Copying crkbd_rev1_default.hex to qmk_firmware folder [OK]
Checking file size of crkbd_rev1_default.hex [OK]

• The firmware size is fine - 25036/28672 (87%, 3636 bytes free)
  `

[drashna]

qmk clean -a and/or make git-submodule again.

[mianqi2016]

It still was there:
arm-none-eabi-gcc: error: .build/obj_ergodox_stm32_default/lib/printf/printf.o: No such file or directory

and I saw in the folder".build/obj_ergodox_stm32_default/lib/", there was only "chibios", no "printf".

[fauxpark]

What is the output of git status and ls lib?

[mianqi2016]

The output for "git status":

`
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git restore ..." to discard changes in working directory)
(commit or discard the untracked or modified content in submodules)
modified: ../../../lib/printf (modified content)
modified: ../../../lib/vusb (modified content)

no changes added to commit (use "git add" and/or "git commit -a")
`

[mianqi2016]

The output of "ls lib" under "qmk_firmware":

`
arm_atsam chibios-contrib lib8tion printf usbhost
chibios googletest lufa python vusb

`

[fauxpark]

Delete the lib/printf and lib/vusb folders, then run make git-submodule again.

[mianqi2016]

Now, it seems OK:

`
While, what does the last sentence "(Firmware size check does not yet support STM32F103; skipping)" mean?

[fauxpark]

You can ignore that, it just means you won't get the % of flash space used by the firmware at the end of compilation:

 * The firmware size is fine - 18670/28672 (65%, 10002 bytes free)
