call of overloaded 'unique_ptr(NULL)' is ambiguous #20

Closed imoldovavan closed 4 years ago

imoldovavan commented 4 years ago

I get an error compiling on Platformio in VSCode. Line 68 and 69 in Pagebuilder.h PageArgument() : _arguments(nullptr) {} PageArgument(const String& key, const String& value) : _arguments(nullptr) { push(key, value); }

Please post your source code.

imoldovavan commented 4 years ago

I used the code from DynamicPage example and insert it into may code. Lines 13-20;76-144;436-450;456 I am using an esp32 from TTGO with display https://github.com/Xinyuan-LilyGO/TTGO-T-Display

I started a blank project with only Pagebuilder library and the DynamicPage example and it compiled without errors. I will try to add the other libraries one at a time to see if I can replicate the error.

Hieromon commented 4 years ago

@imoldovavan Thank you post. In the first place, an error is strange:

call of overloaded 'unique_ptr(NULL)' is ambiguous
                               ^^^^

As you can see from the PageBuilder.h code, the PageBuilder constructor does not quote NULL. It's nullptr. https://github.com/Hieromon/PageBuilder/blob/7da92afd67593b541d5efc700489567b82959b43/src/PageBuilder.h#L68 In the C ++ language standard, there is a clear definitional difference between NULL and nullptr. Refs: https://oopscenities.net/2011/06/17/c0x-nullptr/ However, some libraries importing unexamined legacy C code force nullptr to be redefined to NULL using like #define nullptr NULL, which is a mistake. I suspect some library header files preceding the #include <PageBuilder.h> directive defines nullptr as NULL. To find the causes, you can try moving #include <WiFi.h>, #include <WebServer.h> and #include <PageBuilder.h> to the beginning part of main.cpp. (but they should place after #include <Arduio.h>)

imoldovavan commented 4 years ago

I moved the Wifi, Webserver and PageBuilder includes after the Arduino and it compiled with no problems. `
