Hi,

I have a ESP32 project.
I installed new version today but I only get trouble.

1. some compiler warnings (in previous version), e.g. unsigned int vs. int, conversation are now marked as error... I'm anable to compile & link

2. the linker exit with linker errors 
e.g. WebRequest.cpp.o*: In function AsyncWebServerRequest::_onDisconnect()
FS.h:47: undefined reference to AsyncWebServer  _handleDisconnect(AsyncWebServerRequest*)

It was working in previous version.

I did rescan toolchain and libs and also clean the project an recompile ... but same ..

So whats wrong? Did I miss something?

Please help

EDIT: I have installed 1805.14.1 ... odd this is not on your list

What in the hell ...

no problem ... I dont expect that you working entire night

master branch of https://github.com/espressif/arduino-esp32

newest VS2017 Community v. 15.7.1

--------------------------------------------
rgd. 1) The problem still remains. I disabled vmicro-compiler-Warnings for project, Warnings for Libraries and Warnings for Core
Now its compiling without "cc1.exe*: some warnings being treated as errors". Did you somewhere in that options set -WError ???

rgd. 2) I could fix the 2nd point with linker options by restructuring my project a bit. Interesting, it was working before with old version. So, linking is not problem anymore.
EDIT: Reason was that I'm using https://github.com/bbx10/WiFiManager/tree/esp32 in parallel to ESPAsyncWebserver... Linker got confused in resolving the correct libs...

-------------------------------------
I will try new version tonight ...

Hallo,
... and thanks for the effort ...

>In the last release the warnings were changed to match how the arduino ide works so shouldn't be an issue. 
You are right. If I switch on all compiler warnings in Arduino IDE preferences I get same results.
However, I personally think its stupid since I want to see the warnings, yes, but not thread it as error and stop compiler process. Could you make an option to disable the -WError flag if all warnings switch on? Reason: The remaining warnings (errors) relate to core libs only. I cannot change this....so why stopping compiler process? 

> I will try new version tonight ...
I tested 14.2 last night. There is no difference for me since I restructured my project.

> I combined the WiFiManager, OTA and WebServer into a single espressif core which you can replace in entirety or in part from this zip (I guess you have installed in mydocuments/arduino.espressif)

Hey, cool! Thanks for the wifigadget code. You should publish on git.
My code is a bit different ... I also have no MQTT and no ArduinoOTA. Anyhow, I will test later when other issues (not related to vmicro) have been resolved:
https://github.com/me-no-dev/ESPAsyncWebServer/issues/361

Furthermore, thanks for the hint that I could place libs directly into the toolchain libraries directory. Normally, I use Arduino IDE to get the libs and they are placed all (esp8266 and ESP32) into my projects/libraries directory ... which sometimes brings some troubles... 

Thanks and BR

Thanks both for the update.

@Acuario, very useful note thanks. Yes, I think Visual Micro should now do what the arduino ide does which is allow library files to be overridden. It's in the release notes but is going to cause some issues. Do you think this is a good change for visual micro or a problem?

@drs warnings: I need to understand what the default should be and can probably add a menu item. You can put thse in a board.txt in the project. Visual Micro uses "compiler.warning_flags.more" when warnings are enabled.

compiler.warning_flags.none=-w
compiler.warning_flags.more=-Wall

Change compiler.warning_flags.more= then click save then build.

Makes perfect sense.

I agree a breakage is never good, however if it is broken in terms of different to the arduino ide then it's a confusion and large support issue.

Having said that you are right anyway...

I should have added a menu item to enable the feature to be selective enabled/disabled and also it's a good idea  to show an output message during compile such as "Ignoring library code "foo.cpp" because it exists in the project"

Dunno why I didn't think of that before, will do and sorry about the messing.
