Hi,

 

The different compilers have different syntax for non ANSI C functions, like aligning of types.

In GCC (which SES uses), it is done using __attribute__((aligned(x)).

In the file compiler_abstractions.h in the SDK, this is solved by using this define instead:

__ALIGN(4) type_t my_variable;

 

Best regards,

Håkon

I have tried as follow :uint8_t   socket_receive_buffer[SOCKET_RECEIVE_BUFFER_LENGTH]  __attribute__ ((aligned (4)));

the error is solved，Thanks！
