Hello everyone,
I am implementing a protocol handler. Within my code I have a (complete) struct typedefed to protocol_t
in a routine i want to use the typedef and some raw format, so I initialized the variable like followed:
union { protocol_t data; uint8_t raw[]; }buffer;
I have enabled c99 but get error: #70: incomplete type is not allowed anyway. In the documentation I read: 70: incomplete type is not allowed
Example:
typedef struct { unsigned char size; char string[]; } FOO;
By not declaring a size for the array in the structure, the compiler is not able to allocate a size of the structure. Incomplete types are permitted in --gnu and --c99 modes. Why do I get the error even with --c99?
