I tried to modify an old application. This application was programmed in Borland C++, and the last programmer lost the header files (.h). I can not compile the program with new modifications. The folder of the application project contains the last object files (.obj).

My question is:

Can I convert those object files to header files?

I tried to convert the files using obj2opengl.pl, but it did not work.

    This would be called "decompiling". It can be 'done', using the right tools, fsvo 'done'. In my experience, it's limited at best.. usually better to get a gist and it definitely *won't* result in the 'original header files'. – user2864740 Feb 21 '18 at 00:46
  • If you don't have the source code that was used to compile the object files, then you will have to reverse engineer the object files, such as with a tool like IDA, and then manually create new header files that are compatible with the existing object files. – Remy Lebeau Feb 21 '18 at 02:11
  • All of the content of all four of those comments should be in the answer section. – Lightness Races in Orbit Feb 21 '18 at 02:43
  • Thank you for all your comments, I think it is better try for other way and make a new header files. – Josh Eagle Feb 21 '18 at 15:12
