I'm trying to get side-by-side stable and latest toolchains configured on my Windows 10 PC. I have stable working fine, in as much as I can run menuconfig and build/flash/monitor the hello_world app. For stable, I did not set any global environment variables - instead I set the values in the .bash_profile script. That way, none of the values would conflict with latest.

I'm having trouble with the latest toolchain installation, and I'm running into a problem running menuconfig in the hello_world sample (copied to another directory).

This is my second time through the installer, and I've worked through a few issues, but still run into this same error in menuconfig. Hopefully someone can help me work through this. I'll post relevant information below.

My local directories:

Root directory: c:\tools\esp32-latest, has folders dist, python_env, and tools (along with an esp directory that I added). Also has idf_cmd_init.bat and a few other files.
IDF_PATH: c:\tools\esp32-latest\esp\esp-idf (I chose v4 release in the installer).
IDF_TOOLS_PATH: c:\tools\esp32-latest (not set by me, including before installation)
c:\users\<me>\.espressif: contains dist, python_env, and tools folders.

menuconfig error:

c:\tools\esp32-latest\esp\hello_world>idf.py menuconfig

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

idf.py build

Have you by any chance built the same project first with "stable" and then with "latest" IDF? If yes, please try deleting the build directory before switching versions. The following error indicates that something is wrong with the setting of IDF_PATH, and it may be because CMake caches this variable in CMakeCache.txt:

CMake Warning at C:/tools/esp32-latest/esp/esp-idf/tools/cmake/idf.cmake:14 (message):

No, not the same project. I should have mentioned that my stable tool chain is installed at c:\tools\esp32-stable. It has it's own esp-idf repo clone (v3.3). From there I copied the hello_world sample to home/esp/hello_world.

So that is a technically a different project and folder from the "latest" tool chain folder.

That said, I deleted the build directory under latest's hello_world and tried again. I get the same error.

I edited tools\cmake\idf.cmake to spit out the values of idf_path and _idf_path to see how it was different. It looks like it is doing a case-sensitive comparison because the only difference is the case of my drive letter:

c:/tools/esp32-latest/esp/esp-idf
C:/tools/esp32-latest/esp/esp-idf

Since that seems only to be a warning, I think the value of IDF_PATH is a misleading message. Windows is case-insensitive for file system paths so this difference shouldn't matter.

If I replace that idf.cmake code with the following to negate that, I get the following output.

Code: Select all

    # Environment IDF_PATH should match the inferred IDF_PATH. If not, warn the user.
    if(idf_path)
        string(TOLOWER "${idf_path}" idf_path_lower)

Any idea @ESP_igrr?

From what I can tell, the following command references a directory structure and file that do not exist, and that is why it fails. Why does it have an expectation that isn't met? Is a previous step supposed to have set that up?

C:\Users\drwill\.espressif\tools\xtensa-esp32-elf\esp32-2019r1-8.2.0\xtensa-esp32-elf\bin\xtensa-esp32-elf-gcc.exe -mlongcalls -Wno-frame-address -nostdlib CMakeFiles/cmTC_dffb9.dir/testCCompiler.c.obj -o cmTC_dffb9

Thanks,

I never got it working, and still no help from Espressif.

Hi Kubuś, this seems to be a different error than the one reported by drwill. Can you please try running "xtensa-esp32-elf-ld -v" from IDF command prompt and see if that works?

The system cannot find the path specified.

Hi drwill, can you try creating a new directory (such as build_tmp) in your project, and then running cmake there manually (cmake .. -G Ninja, as shown here: https://docs.espressif.com/projects/esp ... e-directly). It looks like the step where CMake is trying to test the compiler is failing, but this part is not handled by the IDF build system. If it still fails when you run cmake manually, please attach the log file.

It works, I think:

Code: Select all

c:\esp32\esp-idf\xtensa-esp32-elf-ld -v
GNU ld (crosstool-NG esp-2019r2) 2.31.1

But "idf.py menuconfig" is still not working (under Arduino everything is OK, but I prefer Eclipse and esp-idf). Something is wrong with the xtensa gcc compiler, I guess. Bad installation, wrong version or path?

Hi Kamil,

could you try adding the following line to tools/cmake/toolchain-esp32.cmake file in ESP-IDF?

Code: Select all

set(CMAKE_EXE_LINKER_FLAGS "-fno-use-linker-plugin" CACHE STRING "Linker Base Flags")

then delete the "build" directory in your project, and try building again.
