I compiled the project in mingw32 command line.
It only compiles the changes. and much faster.
I attached the output.

So there much be some setting in Eclipse messed up the build?

Thanks

Paul

Output.txt attached.
I didn't change any code. Just compile, it always takes almost a minute to finish.

I am running it on Windows 7.
This is the build output when I start build:
23:08:25 **** Incremental Build of configuration Default for project blink ****
make -j8 all

Thanks guys!
Yes, I have a ESP32-WROVER-KIT.
I just tested the board.
I downloaded the software via COM43.

As shown on my screenshot, I put "COM43" there. Is it correct?
I have been doing other Windows development. large com part number require \\\ in front it.
Is it the case there?
Thanks

Is there a switch for just flash without rebuilding the whole project?
I am using Eclipse.
Thanks
Paul

I thought one is for programming and one is for normal UART from ESP32.
But how can I tell which one is which?
Thanks
Paul

Hello other developers.
ESP32 takes minutes to compile. How do you guys live with the long compiling time?
Every change takes minutes to verify.

I guess at the later stage in the development it is probably fine.
But at beginning it is really slowing things done!

Thanks

I followed every single step from this page
https://docs.espressif.com/projects/esp ... setup.html
But still get unresolved inclusion in the IDC.

Googled for a few solutions, but none of them worked.

Thanks

Paul

I fixed it by myself. Just by going into device manager and find the unsupported device and do a driver update.
