pragmatist!

so what, it compiles no issues

It works fine with CLANG just complaining in GNU GCC.

I did proper ordering in my c++ main file and wherever it required in c library files. And its working fine without error.

Some googling suggests that it's C++ 20 - not 11 - which introduces designated initialisers?

https://stackoverflow.com/questions/18731707/why-does-c11-not-support-designated-initializer-lists-as-c99

https://en.cppreference.com/w/cpp/language/aggregate_initialization

The latter includes the note:

"Note: out-of-order designated initialization, nested designated initialization, mixing of designated initializers and regular initializers, and designated initialization of arrays are all supported in the C programming language, but are not allowed in C++."

Wrong, set the compiler option to ISO C++ 11 (not GNU C++ 11), you'll see it compiles. I am using GCC 7 btw.

You mean this: https://devzone.nordicsemi.com/f/nordic-q-a/19750/sorry-unimplemented-non-trivial-designated-initializers-not-supported ?

RE: Compiler Error: Unimplemented Non-Trival Error

Nguyen Hoan Hoang — Tue, 18 Dec 2018 19:43:56 GMT

that is C++ 11

RE: Compiler Error: Unimplemented Non-Trival Error

awneil — Tue, 18 Dec 2018 17:11:33 GMT

Is that compliant with the Standard, or is that a GCC extension - as mentioned above?

RE: Compiler Error: Unimplemented Non-Trival Error

Actually you can use the field name in the initialization. Only thing require it to work with C++ is the ordering. it has to be in the same order as declared in the struct. For instance if your struct is declared x then y. You need to init as { .x= 1, .y = 2 } not { .y =2, .x =1 }. The later will generate the error.

I assume you also removed the field name, to fix the initialization issue in C++.

So rather than initialize like this {.field1 = x, .field2 = y}, you just initialize like this {x, y}

Mine is working perfectly fine.

RE: Compiler Error: Unimplemented Non-Trival Error

awneil — Mon, 17 Dec 2018 18:17:55 GMT

that would not help with the initialisation issue.

RE: Compiler Error: Unimplemented Non-Trival Error

Roh_Sys — Mon, 17 Dec 2018 18:13:27 GMT

I just changed the parameters in those functions which are using type def struct in macros.

as an example, if there are 7 different type of variable in structure in macros. But you want to change the value of only 3 or 4 parameters. so, instead of that use all the variables in your function but with the default values. (You can change the value if you want ).

And sequence of variables should be same as type def struct.

I am using GNU++11 and GNU11

Thanks.

It would help if you gave the complete message - copied & pasted - unabridged and unedited.

Also the section of code to which it relates.

It sounds, as ovrebekk suggests, like GCC is complaining about C-style structure initialisations which are not supported by C++

As a language extension, GCC does offer some "trivial" C-style initialisations in C++ - so that could be what the message is referring to.

EDIT

Is this the full message you were getting:

That is good to hear!

Do you mind sharing which files you had to change to make it work?

I have solved the problem.

There is minor change in typedef struct they are using.

Unfortunately there is no straight forward way to use C++ with the nRF5 SDK. Many of the SDK files use syntax which is not supported in C++, such as the way many structs and unions are initialized.

There is a request internally to make the SDK C++ compliant, but this is not a high priority task, so it is unknown if or when it will be fixed.

Best regards
