Error: no matching function for call to BufferIO::open(const char*&, int)

Question

//Displayed Error message in eclipse cdt.

- Syntax error
    - candidate is:
    - no matching function for call to ‘BufferIO::open(const char*&, 
     int)’

//BufferIO::BufferIO(const char* filename) {

    // trying to open a a file
    if( (mfile = int open(filename, O_RDONLY | O_DIRECT)) == -1) {
        STDERR("opening file failed");
    }
}

What's the "int" doing before "open"? Also, please post complete error messages. — molbdnilo, Nov 26 '14 at 13:11
How is the function declared? You link with the source/object file the function is in? — Some programmer dude, Nov 26 '14 at 13:11
By the way, take a look at the function signature, and what the compiler expects (what you're being told in the error message). Compare those two signatures. Compare both with the *declaration*. Compare all to the *definition*. — Some programmer dude, Nov 26 '14 at 13:22

There isn't really enough information in your posting to provide a full answer; however, if I had to guess, I would assume that you're trying to either call the C function open() or perhaps fstream::open() BUT, you have already declared and/or defined a BufferIO::open() function. If that guess is correct, then you have namespace issues.

Or, if you're actually TRYING to call BufferIO::open(), then you need to provide us with the source and/or declaration so we can help you determine why it doesn't match.
