error C2678

[Victor Nijegorodov]

Try to declare both flags and flag as int

[_Flaviu]

Yes, but FILE_FLAGS is enum with int values ...

[Victor Nijegorodov]

Then, as Richard already suggested replace this enum with a set of #define.

[_Flaviu]

Agree, but that enum is a part of another struct ... so, how can I put as part of a struct several #defines ?

[Lost User]

Of course you can change it to #defines. The definition of FILE_FLAGS then becomes an int type. And then the rest of the code should compile correctly.

[_Flaviu]

I am not get something, so forgive me. I have moved those enum values as #defines, but of course, now I get error from struct: doesn't know who is FILE_FLAGS flags; from level1 struct.

/*
typedef enum {
FILE_READONLY = 0x00000001,
FILE_HIDDEN = 0x00000002,
FILE_SYSTEM = 0x00000004,

FILE\_DIRECTORY = 0x00000010,
FILE\_ARCHIVE = 0x00000020,
FILE\_DEVICE = 0x00000040,
FILE\_NORMAL = 0x00000080,

FILE\_TEMPORARY = 0x00000100,

....
.....

}FILE_FLAGS;
*/

#define FILE_READONLY = 0x00000001
#define FILE_HIDDEN = 0x00000002
#define FILE_SYSTEM = 0x00000004

of course, FILE_FLAGS enum has disappeared ... obviously, I don't understood something ... but what ?

struct level1
{
FILE_FLAGS flags; // <-- error
....
};

struct level1 { FILE_FLAGS flags; // <-- error .... };

Try

struct level1
{
int flags; // <-- error
....
};

[_Flaviu]

Ok, but even flag is comming as function parameter, just like this:

static void SomeFunction(level1* na, FILE_FLAGS flag)
{
....
na->flags |= ~flag;
....
}

So, I guess I cannot give up FILE_FLAGS enum ... don't I ?

[Victor Nijegorodov]

Change this parameter to be

static void SomeFunction(level1* na, int flag)
{

Add this line somewhere before the first reference to FILE_FLAGS :

typedef int FILE_FLAGS;

[_Flaviu]

I encounter another error if I made these modifications:

data->com = na->flags & ATTR_IS_COMPRESSED; // <-- error C2059: syntax error : '='

(where data->com is int) because now ATTR_IS_COMPRESSED is #define, not part of enum FILE_FLAGS ...

[Lost User]

What is data->com?

That is not the reason. I can only assume that you have done a partial change and some parts of your code are still incorrect. If you still have the FILE_FLAGS enum then it is going to cause problems. It would probably help if you showed all the code portions that are connected. It is difficult to be certain of the answers when looking at only a single line of code.

[Lost User]

I still cannot see enough information. Please provide what I previously requested and reply to this message. Please do not email me personally.

[_Flaviu]

I only said that I updated the previous post.

[_Flaviu]

I only said that I updated the previous post. Ok, I will come with new informations.

[_Flaviu]

The fact is like that: I have an error:

error C2059: syntax error : '='

the error is reported here:

data->com = na->flags & ATTR_IS_COMPRESSED;

where: data is a struct:

struct data
{
.....
int com;
...
};

and na is

RECORD* na;

and RECORD is:

typedef struct {
....
....
int flags;
.....
}RECORD;

and

ATTR_IS_COMPRESSED

is from here (from my modifications):

typedef int ATTR_FLAGS;

//typedef enum {
// ATTR_IS_COMPRESSED = 0x0001,
// ATTR_COMPRESSION_MASK = 0x00ff,
//}ATTR_FLAGS;

#define ATTR_IS_COMPRESSED = 0x0001
#define ATTR_COMPRESSION_MASK = 0x00ff

[Lost User]

Not sure why you posted all that back to front ... However there are a couple of simple mistakes: #define statements do not require an = sign. They should be

#define ATTR_IS_COMPRESSED 0x0001
#define ATTR_COMPRESSION_MASK 0x00ff

The name data refers to a struct definition, not a variable. You need something like:

typedef struct
{
.....
int com;
...
} DATA;

DATA* data;

I am assuming that you actually assign the memory required for both structures at some point further on.

[_Flaviu]

That was the problem, on #define: I assigned with '='. My bad !
