NFC Tag type 4 and GCC

[MarcoTull]

Hi all, I am porting my 100% working code from keil to use C++ and GCC and when I use the macro NFC_NDEF_MSG_DEF to initializate the NDEF message I receive the following message from the compiler:

> >NFC.cpp(50,2): note :  in expansion of macro 'NFC_NDEF_MSG_DEF'
1>  NFC_NDEF_MSG_DEF(welcome_msg, MAX_REC_COUNT);
1>  ^~~~~~~~~~~~~~~~
1>../libraries/nfc/ndef/generic/message/nfc_ndef_msg.h:127:9: sorry, unimplemented: non-trivial designated initializers not supported
1>         }
1>         ^
1>NFC.cpp(50,2): note :  in expansion of macro 'NFC_NDEF_MSG_DEF'
1>  NFC_NDEF_MSG_DEF(welcome_msg, MAX_REC_COUNT);

it looks like some issue with the nfc_ndef_msg.h when I call the macro NFC_NDEF_MSG_DEF with using GCC and C++ code. Are the NFC libaries not compatible with c++ code?

some one can give an advise?

Thanks, Marco

Hi,

This is not supported by C++, please google the error to read more about it. This commend give a suggestion on an alternative approach.

Note that exept from the header guards, our SDK does not have support for C++.

Best regards,

Jørgen

Hi Jørgen, I solved my issue, now the NDEF message macro is working very well :) The issue was something with GCC and the struct values assignments it should be in the same order they are declared in the struct nfc_ndef_msg_desc_t. I hope it helps someone else
