c++ - "cannot open output file filename.exe: Permission denied" -

i have learned c++ , trying make program using windows.h header. using dev-c++ compiler , getting 3 errors can't find solution to.

these errors:

cannot open output file filename.exe: permission denied
[error] ld returned 1 exit status recipe target 'filename.exe' failed

here code:

#include &#60windows.h&$62 #include &#60iostream&#62 #include &#60fstream&#62 #include &#60string&#62 #include &#60vector&#62 using namespace std;  hwnd textfield; /* input window goes */ lresult callback wndproc(hwnd hwnd, uint message, wparam wparam, lparam lparam) { switch(message) {     case wm_create:              createwindow("static",             "docjoin document combiner",             ws_visible | ws_child | ws_border,             20,20,300,25,             hwnd,null,null,null);             break;      /* upon destruction, tell main thread stop */     case wm_destroy: {         postquitmessage(0);         break;     }      /* other messages (a lot of them) processed using default procedures */     default:         return defwindowproc(hwnd, message, wparam, lparam); } return 0; }  /* 'main' function of win32 gui programs: execution starts */ int winapi winmain(hinstance hinstance, hinstance hprevinstance, lpstr lpcmdline, int     ncmdshow) { wndclassex wc; /* properties struct of our window */ hwnd hwnd; /* 'handle', hence h, or pointer our window */ msg msg; /* temporary location messages */  /* 0 out struct , set stuff want modify */ memset(&wc,0,sizeof(wc)); wc.cbsize        = sizeof(wndclassex); wc.lpfnwndproc   = wndproc; /* send messages */ wc.hinstance     = hinstance; wc.hcursor       = loadcursor(null, idc_arrow);  /* white, color_window #define system color, try ctrl+clicking */ wc.hbrbackground = (hbrush)(color_window+1); wc.lpszclassname = "windowclass"; wc.hicon         = loadicon(null, idi_application); /* load standard icon */ wc.hiconsm       = loadicon(null, idi_application); /* use name "a" use project icon */  if(!registerclassex(&wc)) {     messagebox(null, "window registration failed!","error!",mb_iconexclamation|mb_ok);     return 0; }  hwnd = createwindowex(ws_ex_clientedge,"windowclass","docjoin",ws_visible|ws_overlappedwindow,     cw_usedefault, /* x */     cw_usedefault, /* y */     683, /* width */     730, /* height */     null,null,hinstance,null);  if(hwnd == null) {     messagebox(null, "window creation failed!","error!",mb_iconexclamation|mb_ok);     return 0; }  /*     heart of our program input processed ,      sent wndproc. note getmessage blocks code flow until receives something,     loop not produce unreasonably high cpu usage */ while(getmessage(&msg, null, 0, 0) > 0) { /* if no error received... */     translatemessage(&msg); /* translate key codes chars if present */     dispatchmessage(&msg); /* send wndproc */ } return msg.wparam; 

}

and here makefile.win:

i spent 3 hours doing research , troubleshooting , stumped. first time using c++ compiler, meaning first program.

you have change file location.

note: not save file in program files & program files (x86) in microsoft windows.

you can use path example c:\user\.....
