Yes. There's no schedule yet for removal of the GNU Make based system. It remain the default build system for IDF v3.x, and we plan to make CMake the default for IDF v4.0. However GNU Make will also be supported for v4.x.

So the earliest we could decide to remove GNU Make support would be IDF v5.0 (as yet unscheduled, but definitely not this year). If we decide this then it will be based on the maturity of CMake support, and we will give plenty of notice.

(Regarding the general question of support - releasing of bug fixes, etc - for older major releases, we're in the process of coming up with a more formal policy about this which we will release ASAP.)

I just wanted to update that CMake works without any problems so far for me.

Compilation is very very fast comparing to MSYS2 MinGW 32-bit.
If anyone is interested how to set up CMake for ESP-IDF RTOS under Windows 10 and Visual Studio Code - let me know and I post small guide.

I would be very interested about any guide explaining how to setup CMake with any other IDE apart of Eclipse. Visual Studio Code sounds great. :D

I have a favor to ask. There are a few bugs that have been fixed in master on the bluetooth end that have not been reflected on the feature/cmake branch. I know it's only experimental, but would you all be able to merge master into feature/cmake?

We're in the process of merging feature/cmake into master, so hopefully it will be available (without needing a separate branch) very soon.

That’s great! Thank you. My company is in the middle of a very rushed evaluation of the esp32 platform, along with a couple others. One requirement is that it integrate easily into our cmake build system, and another is that we can demonstrate simultaneously running WiFi and Bluetooth. A bug that’s on the cmake branch (it isn’t caused by the cmake branch. It exists in master as well at that point in the repo) disconnects Bluetooth as soon as WiFi starts up. That bug is preventing us from checking that final box.

If you happen to have a not-ready-for-master, but still functional branch that I could help test, that would be great. Otherwise, I guess I can just try to merge in the Bluetooth changes from master into feature/cmake locally and then wait for the release by you all.

Hi Espressif Developer or SDK Team,

We are working on ESP32 IDF 3.1 Release for our one of product and I just read about few post of CMAKE base ESP32 Preview Release IDF which will be going to release into ESP32 IDF 4.0 or 5.0

So, What will be the state for older GNU make based system which are running on older release once CMAKE based IDF will be merged into master and released as stable release?

So, Still we will get IDF 4.0 or 5.0 on GNU make based system or it will be completely going to be obsolete?

I am afraid of that support for GNU make based IDF once CMAKE based stable IDF will be released.

Also, Would you please let me know tentative schedule for that release?
Regards,
Ritesh Prajapati

CMake preview is currently available in IDF v3.1 release and in master branch. It is a preview — some things are expected to change. It is expected to be stable and fully functional in IDF 4.0, at which point it will become the recommended way to use ESP-IDF. GNU Make based build system will still be supported (but will not receive new features). There is no plan yet for removal of GNU Make based build system.

Hi,

Thanks for Reply and information regarding that.

But, What if we want to continue GNU based system forever with latest update inline with CMAKE based system? can we get that type of support at that time? or once CMAKE build system will be released as stable release then GNU make build system will not be maintained means not updated after that?

Hope this will clear our concern regarding CMAKE vs GNU MAKE build system usage.
Regards,
Ritesh Prajapati
