after refresh git invalid application of 'sizeof' to incomplete type 'struct __lock'

Postby zamek42@gmail.com » Sun Jul 04, 2021 6:25 pm

Hi All,

Today after I've refreshed idf (git pull origin master &
git submodule update) I've tried to compile my application and I've got the following error:

esp-idf/components/newlib/locks.c:240:23: error: invalid application of 'sizeof' to incomplete type 'struct __lock'
_Static_assert(sizeof(struct __lock) >= sizeof(StaticSemaphore_t),

I use debian Linux unstable.

How can I fix this error?

thx,
Zamek

Are you sure your toolchain is also up-to-date? It should give you a warning if that's not the case.

Hello,

There is no problem with tool, but I've reinstalled both esp32 and tools. Unfortunately the problem is exists:

hi,

It solved like this: I had to remove whole build directory and idf.py build.

thx,
Zamek

Same issue here.
Even after removing the whole build directory, idf.py build will continue to generate the same error:

This issue is related to using the older version of the toolchain (esp2020-r3) with newer version of ESP-IDF that requires esp2021-r1 toolchain.

If you see the following in the error log:
/home/zamek/.espressif/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc
Then esp-2020r3 toolchain is being used.

Please follow the steps below to resolve this (assuming you are using Linux):

1. go to esp-idf directory and run install.sh script (./install.sh). It should say that esp2021-r1 toolchain is either being downloaded, or is already downloaded.
2. source the export script (. ./export.sh).
3. run "xtensa-esp32-elf-gcc --version" to confirm that esp2021-r1 toolchain is now being used
4. go to your project directory and run "idf.py fullclean". This will clear the CMake cache file, that records the toolchain being used
5. build the project again
