Re: Using Borland C++ object files in VC++

I have an obj file, that is compiled with Borland C++ in MS-DOS, and i

in obj file. Now, i need to use this file in a program written in VC++
6 in XP.

I know Borland uses OMF and VC++ uses COFF, and this is not the
problem since visual studio can convert OMF to COFF. I guess real
problem is about different linker name conventions. How can i solve
this? Are there any tools about this conversion?

Hi,

I don't have C++ experience with DOS, but:

If linker and naming conventions were the only problem you'd be lucky.

Even if this is / were not the case, object files are never portable between
compiler versions, and definitely not between compiler vendors, and even if
they were, your object file was not compiled for a win32 subsystem.

Object files does not contain any dos-specific functions, only some
mathematical algorithms are implemented there. I know VC++ dlls can be
imported by Borland using implib, impdef etc, and this proof of the
conversion is why i am hopeful.


Maybe someone with DOS experience will chime in to say that I am wrong, but
I think it is impossible to use that object file with VC6.
