constructor required for `unordered_map`? about arduinofake HOT 7 CLOSED

Greetings @FabioBatSilva, just wanted to mention that with some help on the cpputest forum, I was able to clear this.

https://github.com/graial/ArduinoFake-cpputest

my forked repo is now building but encountering a different error which I haven't yet investigated. If I can't sort that out, I'll open up a different issue when i get the chance

cheers

Hi,

Might be something related to cpp 12.

You might wanna start with one of the examples and -std=gnu++17

from arduinofake.

Good evening and thank you for your response. No luck with gnu++17 though.

these are the default compiler flags used by cpputest

-pedantic
-Wno-missing-prototypes
-Wno-strict-prototypes
-Wno-c++14-compat
--std=gnu++17 // was originally --std=c++11
-Wno-c++98-compat-pedantic
-Wno-c++98-compat

from arduinofake.

So... if you comment out all of the CppUTest code and just do the #include of the ArduinoFake then it already occurs ?

from arduinofake.

yes, correct.
and if that #include is removed, the test suite completes successfully

So there seems to be something in the makefile or compiler chain that is unhappy

from arduinofake.

The ArduinoFake example projects and tests (using Unity) work for me.

I attempted to use the same approach to build cpputest in this repo and it fails on the same error.

from arduinofake.

I've now gotten this to a minimal reproducible example via cmake.

i believe that the lines:
set(CMAKE_CXX_STANDARD 17) set(CMAKE_CXX_STANDARD_REQUIRED ON)

establish the -std=gnu++17 specification
