Yes simple hello world sketch failed to compile in Arduino but compiled in Eclipse. I'm now in Switzerland so might not have time to build environment on my laptop until I get back at the end of the week but I'll keep you informed.

The strange thing is that I used the toolchain that successfully built in Eclipse.

I'll have to build the toolchain a different way and see if the fault goes away.

I have loaded up Mikhail's Unofficial Development Kit for Espressif ESP32 version 0.0.6 and SDK example compiles without error. Taking the toolchain into the Arduino environment with a simple 'Hello World' sketch fails in the same way Rudi described. C:\Program Files (x86)\Arduino\hardware\espressif...

In Windows 10 the 'at' command has been deprecated so you need to change the line

at > nul

to

in the file

install-mingw-package.bat

I'm definitely interested.

Merry Christmas from here in the UK.

@esprabbit If you send (PM) me the text and any drawings/diagrams/tables I'll have a go at translating.

Use desoldering braid. Much easier than a solder sucker. Add some solder (I know it sounds counterintuitive) and wick it off.
