enum in struct compile error

Question

as title said,the code blow gives error with g++:

error: expected specifier-qualifier-list before ‘logType’

Code:

enum 
{
     log_memory,
     log_filesystem,
     log_default
}logType;

typedef struct
{
     logType type;
     void (*logPrint)(char* msg);

}logsystem;

By the way, in C++ the typedef trick for structs is not necessary. Just write struct logsystem { ... }; — Matteo Italia

This:

enum
{
    ...
} logType;

declares a variable, not a type. You want this:

enum logType
{
    ...
};

[Side-note: Usual C++ conventions are to have type-names start with a capital letter.]

When declaring an enum you specify the name of it right after the word enum, it's not like using typedef to create an alias for a struct.

enum logType
{
     log_memory,
     log_filesystem,
     log_default
};
