Now can't build with Core 2.3.0?

[JamesNewton]

Just started trying to use this library yesterday, and I'm thinking your fixes to support 2.4.0 might have broken support for 2.3.0?

I really don't want to upgrade to 2.4.0 before it's had a chance to bleed a bit...

...I guess I will try to download the prior version of your library, but figured I should mention this first.

[JamesNewton]

Yeah, commit 9b0cc37 builds under 2.3.0

People who don't sit on the bleeding edge of everything might want to know.

[Uksa007]

I have similar errors under 2.3.0 I have changed the library.json back to commit 9b0cc37 but still had error found I need to implement c2d4c16 to resolve.
Why are they committing PR for 2.4_RC when they don't work with the current production release !

[xoseperez]

It would have been better to commit 036ea44 to a "staging" branch and keep master compatible with stable 2.3.0. I'm too receiving issues in ESPurna firmware and fauxmoESP library due to this...

[me-no-dev]

it would have actually been best to have some sort of define switch that could be used to make it compatible with both but seems that the lwip headers were not updated together with the lib :(

[kherNI]

I'm running 2.4.0 and I'm getting the same errors.

[me-no-dev]

@kherNI how come? Changes were checked. Maybe you are running ssl?

[kherNI]

I just tried with the standard example. The Board Manager has : https://github.com/esp8266/Arduino/releases/download/2.4.0-rc2/package_esp8266com_index.json

[me-no-dev]

Something is wrong. This can not be 2.4.0

[kherNI]

You're right. I just did a git clone for the standard ESP8266 and this repository and now it compiles fine. Sorry about that. Thanks for all your help on this platform!

[universam1]

could you @me-no-dev maybe add a condition based on const char * getSdkVersion() to solve this here. We got so many devs having issues because of that.

[andig]

Fixed in master and can be closed?

[fdarling]

I still get the compilation errors when using the latest master branch of this project and the following setup:

Ubuntu 16.04 (amd64)
Arduino IDE 1.8.5 (also tested 1.8.2)
esp8266 v2.3.0 installed via the boards manager

I wouldn't consider this closed, it's a problem because it doesn't work "out of the box" with a standard installation!

Is this a matter of putting some macros somewhere to select between different function signatures?

[fdarling]

The root problem seems to be the hard-coding of "long" instead of "err_t". err_t is defined in lwip/err.h, and in my case maps to "s8" (signed char).

I created a patch, but I'm a noob to git/github, so I don't know the proper way to upload it. I put it inline here wrapped in a triple backtick block. If this work for you, please speak up and let's get this into the master branch!

@fdarling that worked perfectly for me, thanks!
