Hi,

I want to code in C++ using Visual Studio Code. I am able to compile and run my C++ code including a simple component.

Now I want to unit test my component. However, I can't get the unit tests to work. I'm getting the following errors when I try to compile the test app.

Code: Select all

[806/965] Generating test_tjpgd_logo.h
FAILED: esp-idf/esp32_test/test_tjpgd_logo.h

and

Code: Select all

'xxd' is not recognized as an internal or external command,
operable program or batch file.

Anybody seen this before?

You need an extra helper tool called 'xxd', which is used to convert the jpeg image into something that can be embedded in the binary.

Thank you.

I need it for Windows. Is it part of some toolset? I found one but I need Cygwin for that. Will that work?

No clue, but it may be easier to just disable that specific unit test somehow, it's pretty old and tests ROM code that is well-proven by now.
