Solve problems that class members cannot find

I added a function declaration getE (char * c, int x) to the tga_writer class of the tga file and defined it in the tga.cpp file.

A new MFC project is created. When a button is pressed, the getE function is called, but the error C2039: "GetE" is not always a member of "tga_writer". When calling other original functions in tga_writer, the system will not prompt an error, why?

Have you set getE to inline, sometimes call the inline function outside the class, this will be the case

Not set to inline

What about the code?

chensunshine

class tga_writer
{
  FILE * Pfile;
  int width, height;

public:
  int GetE (char * filePath, int X, int Y, int compRatio);
}

defined in tag.cpp

A.cpp:
 tga_writer tw = new tga_writer ();
 tw-> GetE (...........);

2003 error: error C2039: "GetE": not a member of "tga_writer"

class tga_writer
{
FILE * Pfile;
int width, height;

public:
int GetE (char * filePath, int X, int Y, int compRatio);
};
void tga_writer :: int GetE (char * filePath, int X, int Y, int compRatio) ();

void main () {
tga_writer * tw = new tga_writer;
tw-> GetE ();
delete tw;
}

You did not achieve

int GetE (char * filePath, int X, int Y, int compRatio);
