I want to use some basic struct in C like the following:

struct p {
    int a;
    int b;
    p * next;

However, it fails to compile with an error: parse error before "p" on the line with p * next;.

Do you have any idea what the reason could be for this problem?

Was it helpful?


C structs live in a different namespace and have to be explicitly scoped, thus:

struct p {
    int a;
    int b;
    struct p * next;

And don't forget the semicolon at the end! :-)

You can pretend you're in C++ thus: typedef struct p { /*...*/ } p;. But I think that next will still have be declared as above.
