Missing file "Hash.h"

Missing file "Hash.h"

[probonopd]

This is still an issue for me. probonopd/WirelessPrinting#118

[ivankravets]

@kuthullu just add this line into the of one file from src folder

#include <Hash.h>

[me-no-dev]

that is platform.io's fault. the library is in the ESP core libs.
One fix is to add #include <Hash.h> in AsyncWebSocket.h

[kuthullu]

I searched the Lins directory and the generated libs for the project, the
file doesn't exist...

It isn't included by default, but explicitly including it on your main.cpp solves the problem... maybe this is worth a note on the docs ? Anyway, thanks for your time, you really helped me

[me-no-dev]

it should really be fixed on platform.io side :) it follows Arduino guidelines and should by all means work.
@ivankravets can maybe shed some light?

[ivankravets]

A deep library search is turned off by default. We had it enabled before but a lot of users had the problems with it. The easy way is to include required library in the src files. In this case, PlatformIO will understand that you really need this library, otherwise you can enable http://docs.platformio.org/en/latest/projectconf.html#lib-dfcyclic

[me-no-dev]

@ivankravets has to be in one of the headers, correct?

[me-no-dev]

can I make a header that will actually not be included in the build and define the required libs there?

[ivankravets]

@me-no-dev no matter. In any place/ in any file (*.c, *.cpp, .h, etc.)

[me-no-dev]

it is in the CPP file here

[ivankravets]

@me-no-dev your code is fine. This is a behaviour of PlatformIO 2.0. We are working on the PlatformIO 3.0 where the Library Manager and Library Builder will be significantly refactored.

The one reason why deep finder is turned off is that current Library Builder doesn't handle #ifdef and etc constructions.

Conclusion

• @me-no-dev you don't need to change your code.
• @kuthullu please include #include <Hash.h> library manually.

P.S: It should work without any changes with PlatformIO 3.0.

In 3.2.1 it doesn't work. You have to include <Hash.h>

[ivankravets]

@fab33 You can specify extra dependencies for a project using lib_deps option

lib_deps = Hash

[ivankravets]

@me-no-dev do you have any info when new release of ESP8266 for Arduino will be issued?

[me-no-dev]

@ivankravets asking for 2.4.0? I would rather have it sooner than later, but it depends on Ivan's time and by the looks of it.... it will be maybe January. There are some goals that need to be covered by the end of the year.

[ivankravets]

@me-no-dev Thanks! We will wait for that!
