Error lnk2019: unresolved externa l symbol _ iob referenced in function _ output_message @ 4

1. Vs2003, vs2005, vs2008:
   
2. 0. Replace libjpeg. Lib in libjpeg_vc7 with libjpeg. Lib of vc6 in win32depends/lib.
   
3. 1. Set include and lib to the include and library directories of vs200x.
   
4. 2. Set win32depends/include and win32depends/lib to the include and library directories of vs200x.
   
5. 3. Enable win32builds/libnge2.dsw to compile and convert all files.

14. File _ iob [3] = {__ iob_func () [0], _ iob_func () [1], _ iob_func () [2]};
    
15. The above method can also be solved, but this part of code should be replaced every time you create a new file. It is better to change the Lib
