Cannot build project in Eclipse (IEP-173)

[michaliskon]

I've been working with Arduino IDE and am now trying to migrate to ESP-IDF using eclipse. I cannot build a copy of the project https_server

Console output:

Also I noticed that all the libraries included at the top of main are "unresolved inclusion".

Apparently I have not set something correctly, but I cannot figure out what it is.

include called with wrong number of arguments. include() only takes one file.

Hello, It seems to be more of a program error. Check if you can identify and fix this. Let us know if you need more help with this.

"unresolved inclusion" errors will disappear after the build completion.

Hi, I haven't used eclipse before and I do not know how to proceed.

I would like to request some more help with this.

@projectgus @igrr Could you please help him with this error. Thanks

Could you please share a sample project to reproduce this error.

[michaliskon]

I have zipped it and uploaded it. It is the https_server under protocols examples from esp-idf.

HTTPS_server.zip

I'm able to build the same project you've provided without any compilation errors. The problem could be with the CMake version or something else. Will update you.

I am looking forward to.

Hi @michaliskon ,

At the moment ESP-IDF doesn't support spaces in the path to ESP-IDF or the project.

C:\Users\User1\Dropbox\coding\Eclipse IDE C C++\HTTPS_server\build

If you remove the spaces in "Eclipse IDE C C++" and reopen & rebuild the project, then it should work.

Sorry for the inconvenience. We plan to revisit this in the near future.

[michaliskon]

Thank you. It works fine now :)

Thanks @projectgus. Good to know.
