Hi.

I'm trying to compile default example (hello_world) and getting error during compile.

My setup:

1) win10;

2) idf version v3.3-rc-8-gbeb34b539
got this one from release/v3.3 brach with command:

Code: Select all

$ git clone --recursive https://github.com/espressif/esp-idf.git --branch release/v3.3

3) toolchain: 20181001
got this one from this link:
https://docs.espressif.com/projects/esp ... hain-setup

Code: Select all

$ xtensa-esp32-elf-gcc --version

I want to use STABLE branch of IDF with GCC compiler. What versions of compiler do I need to use?

Something unexpected has happened here because the 20181001 Windows package should include a xtensa-esp32-elf-gcc 5.2.0 release, not one based on gcc 8.2.0 (that is a 2019 release, as per the "esp32-2019r1" in the crosstool version string).

The errors you're getting are due to the toolchain mismatch. Probably there is also a warning printed earlier in the build log about "Expected to see toolchain 5.2.0 but the toolchain version is 8.2.0" or similar.

Suggest re-unzipping the toolchain zip and checking that there isn't another toolchain on the PATH which is replacing the one in the MINGW32 environment. Then the build should succeed.

Hi ESP_Angus,

thank for assistance.

Indeed, toolchain was modified by idf_windows_installer (https://docs.espressif.com/projects/esp ... -installer) while I tried other options.
Now I have changed to version 5.2.0:

Code: Select all

$ xtensa-esp32-elf-gcc --version
xtensa-esp32-elf-gcc.exe (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a5) 5.2.0

But now I having another problem:

Code: Select all

$ make menuconfig
DEFCONFIG
make: *** No rule to make target «defconfig», needed by «menuconfig».  Stop.

IDF seems not corrupted:

Code: Select all

user@DESKTOP-KI53PC4 MINGW32 /c/ESP32/TOOLS/esp-idf
$ git status
On branch release/v3.3
Your branch is up-to-date with «origin/release/v3.3».

nothing to commit, working directory clean

Version:

Code: Select all

user@DESKTOP-KI53PC4 MINGW32 /c/ESP32/TOOLS/esp-idf
$ git describe
v3.3-rc-8-gbeb34b539

What else should I try?

Hi Al,

Thanks for the detailed update and sorry it's still not working.

What is the IDF_PATH variable set to?

Hi ESP_Angus,

My IDF_PATH:

Code: Select all

$ printenv IDF_PATH
C:/ESP32/TOOLS/esp-idf

Example which I'm trying to compile is hello_world , I moved it from idf folder to
C:/ESP32/Projects/BASE/hello_world

its bare project:

Code: Select all

user@DESKTOP-KI53PC4 MINGW32 /c/ESP32/Projects/BASE/hello_world
$ ls
CMakeLists.txt  main  Makefile  README.md

No spaces in path to project.

UPDATE

I have completely delete esp-idf folder and clone it again with command

Code: Select all

$ git clone --recursive https://github.com/espressif/esp-idf.git --branch release/v3.3

And now...

IDF have other version!

Code: Select all

$ git describe
v3.3-rc-24-g148a26980

It occurs that stable v3.3 branch still in development

https://github.com/espressif/esp-idf/co ... lease/v3.3

During August more then 10 commits to release branch.

This is confusing me.
Are there any really STABLE branch, which I can use any time and be sure that this code is not modifying?

release/v3.3 is a release branch not a release version. Our release versions are git tags, not branches.

v3.3 is not yet a stable release, so the latest pre-release is v3.3-rc. The v3.3 final release (due very soon) will be based on the "release/v3.3" branch, though.

Right now the latest stable release is v3.2.2

Hi ESP_Angus,

thanks for clarifying!

P.S. Example from IDF version v3.3-rc-24-g148a26980 compiled without issues.
