Build errors, related bugs 618,622,683

[ollyru]

Hello!

Build errors: I think it's related bugs 618,622,683.

Three times repeat one thing action. Press "F1" -> "Arduino Verify". Getting an error twice. Third time surprise: compiled without errors!

I built a separate project to simulate this error. Use incremental build - it's important. Project and pic's described error attached here:

Build_erros.txt

Blink_error.zip

In the second picture function prototypes added: why are they not in the first file?

[ollyru]

For the same reason, by the way, I think the wrong conclusion is made before compiling that the files have changed and it is necessary to rebuild the entire project ("Build options changed, rebuilding all") if I change just only main (blink.ino) file. Although the other files in fact has not changed. But it's really just a guess.

And yet, I forgot to add: in the standard Arduino 18.8.6 no errors in the Assembly.

@ollyru do you use Arduino IDE 1.8.7 and build error? when use Arduino IDE 1.8.6 , there is no error.
Arduino IDE 1.8.7 has some breaking changes, it will install board package and library failed, So it is recommended that you install version 1.8.6.

No, i am already use version 1.8.6, only, i readed description for plugin :-) May be it depended from my used libraries... -- Отправлено К-9 Mail для Андроида 29 ноября 2018 г. 5:46:15 GMT+03:00, Chen Zhang <[email protected]> пишет:

@ollyru yes, if code only support old libraries ,then you install new version libraries , verify and upload will failed, or if code support new libraries, then you install old version libraries, verify will fail too..
now do you resolve this issue ?

[ollyru]

Not yet. Manually delete "build" directory before every build. First (clean) build always performed ok.

[czgtest]

@ollyru I will investigate it

[czgtest]

@ollyru I open an issue to Arduino IDE, arduino/Arduino#8271

Great! Thank you very much!!! It works (without nested build path)!
