Error when compiling with xtensa-esp32-elf
Hi,
When I compile the example without modifying anything, I got this error:
/home/fgh/esp/xtensa-esp32-elf/xtensa-esp32-elf/sys-include/stdlib.h:155:44: error: expected initializer before '__result_use_check'
void *reallocarray(void *, size_t, size_t) __result_use_check __alloc_size(2)

void * aligned_alloc(size_t, size_t) __malloc_like __alloc_align(1)
^~~~~~~~~~~~~
It's so confusing...

Re: Error when compiling with xtensa-esp32-elf
Hi fgh1999,
We need some details to try and tell what the problem is. Can you please share your host OS, ESP-IDF version, the full command line you are running and all of the build output (not just the error lines). Plus any other details which may be relevant.
Thanks,
Angus

Re: Error when compiling with xtensa-esp32-elf
Thanks for the extra details. I see from the log output you're using ESP-MDF.
Current version of ESP-MDF is based on ESP-IDF V3.2, so you'll need to follow the V3.2 setup guide here:
https://docs.espressif.com/projects/esp-idf/en/v3.2.2/
This version of the guide has the download links for the correct version of the toolchain.

Re: Error when compiling with xtensa-esp32-elf
I'm having this problem as well, following update to ESP-IDF (master branch), and upgrade of the compiler. I read This github issue: https://github.com/micropython/micropython/issues/4850.
Do I really need to downgrade crosstool-ng to 1.22? That's harsh, if so. Any advice?

Re: Error when compiling with xtensa-esp32-elf
You don't need to use crosstool-ng at all unless you want to build your own toolchain, but you will need to install an earlier toolchain version (gcc 5.2.0) that was built with crosstool-ng 1.22.
You can find this by following the Getting Started guide for the current stable release (v3.2.2):
https://docs.espressif.com/projects/esp-idf/en/stable/
Re: Error when compiling with xtensa-esp32-elf
ESP_Angus, thanks for your help but following your instructions causes this output (which is why I upgraded to 8.2 in the first place).
It builds. But not without lots of noise and disclaimer. Any idea how to rectify this?

Re: Error when compiling with xtensa-esp32-elf
What version of IDF do you have and how did you get the IDF code (via Micropython or a standalone git clone or some other method)?
If you're using ESP-IDF master branch (v4.0-dev), then you will need gcc 8.2.0 for this. For earlier ESP-IDF versions (v3.x, such as the version shipped with MicroPython) then you will need gcc 5.2.0.

Re: Error when compiling with xtensa-esp32-elf
Stand-alone git request. Pulled fresh last night. By your hypothesis, I'm on 4.0. I will revert to latest 3.x and report back. Thanks again, ESP_Angus.
