Errors when using esp-idf v4.2

[Dreeke]

Hi,

I have successfully created, build and debugged the blink example on my own hardware. So far so good 🙂

I have upgraded esp-idf to the latest release, v4.2, by means of VisualGDB itself.

I tried to do the same as before. The creation of the example project (blink again) gives errors:

CMake Error at C:/Users/ara/AppData/Local/VisualGDB/CMake/share/cmake-3.15/Modules/CMakeTestCCompiler.cmake:60 (message):
The C compiler

"C:/SysGCC/esp32/opt/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc.exe"

is not able to compile a simple test program.

It fails with the following output:

CMake will not be able to correctly generate this project.

I guess that some files are missing… how should I get it working?

I found my error. The point is mentioned here: https://visualgdb.com/documentation/espidf/#buildproblems

I fetched a version from Github which is not the way to go. I have followed the instructions and installed the latest version from here: https://gnutoolchains.com/esp32/

That solved this problem 🙂
