Compile error in example wiring-blink

[No3x]

I want to play around with your testing framework but can't compile the example wiring-blink. I get this error for each occurence of std::strstr:

.piolibdeps\ArduinoFake_ID1689\src/ArduinoFake.h:33:14: error: 'strstr' is not a member of 'std'
if (std::strstr(typeid(*var).name(), #mock)) { \
^
.piolibdeps\ArduinoFake_ID1689\src/ArduinoFake.h:79:13: note: in expansion of macro 'ArduinoFakeReturnInstaceOf'
ArduinoFakeReturnInstaceOf(p, Serial)
^~~~~~~~~~~~~~~~~~~~~~~~~~

I'm on windows with mingw-w64: gcc-7.1.0 platform information: https://pastebin.com/ZCCbF3E9

I did not find any information on this. Maybe you know the reason?

Hi @No3x,

I'm guessing strstr is not part of the std in mingw-w64: gcc-7.1.0 It might be missing a #include <cstring> here ArduinoFake.

Can you give that a try ?

[No3x]

I already tried this lines in all variants:

#include <iostream>
#include <cstring>
using namespace std;

without any success.

EDIT: gosh.. I have edited the ArduinoFake\src instead of the ArduinoFake\examples\wiring-blink\.piolibdeps\ArduinoFake_ID1689\src all the time..

Now the tests compiling and passing. Sorry! What compiler do you use?

[FabioBatSilva]

It might not be using the same version.. What do you get when running the tests in the root directory ?

cd path-to/ArduinoFake
pio test

[No3x]

pio test in the root fails like before. But with

#include <iostream>
#include <cstring>

added it does not.

[FabioBatSilva]

Cool..

Can you send a PR ?

[No3x]

Of course

Could fix this by setting build flags to build_flags = -std=gnu++11 -O3 -Wa,-mbig-obj https://stackoverflow.com/questions/16596876/object-file-has-too-many-sections http://discourse.chaiscript.com/t/compiled-in-std-lib-with-mingw/66 https://forum.qt.io/topic/59978/error-file-too-big/6

I really hate this C++ compiler jungle.

Please let me know if I should add these flags too.

Hello, i have added #include <cstring> and it works finally.

[No3x]

@Sparow199 thanks for confirming this. There is still a pending PR that should fix this. I guess you don't compile on Windows/MinGW - because this introduces a new issue described in my last comment.
