MPLABX XC16 unable to resolve built-in identifier __builtin_dmaoffset


MPLABX XC16 unable to resolve built-in identifier __builtin_dmaoffset

should help you out __builtin_dmaoffset() need to know the real address in order to calculate the DMA offset value. Try as follows-
code :
#define MSG_BUF_LENGTH 32

int main(void) {
    ....

    unsigned int ecan1MsgBuf[32][8] __attribute__((space(dma),aligned(MSG_BUF_LENGTH*16)));
    DMA1STA=__builtin_dmaoffset(ecan1MsgBuf);

    ....
    }

I hope this helps you . constexpr is a new feature of C++11. You need a C++11 capable compiler (like g++4.8) and have to enable the C++11 extensions when you compile a program:
code :
g++ -std=c++11 main.cpp -o test

I wish did fix the issue. strsep is not part of the C standard library.
So you'll have to code it yourself, or find a version.
