Borland C++ question

u have tried or you just want to know ?
the c language doesn't changes .. only changes could be ide related .. maybe scripts format .. but also they will be easiley upgraded as the new versions usually support older but the converse is optional .

My company have bought some code that they originally just had the executable for.

The project file says

VERSION = BCB.04.04

I have tried compiling in release 5 and 6 but no luck.

Version 5 says that System::PByte does not exist (system.hpp I think)

version 6 gives specific errors in code we have bought, which should have compiled in version 4.

In case of c++ builder products the newer versions should be able to compile code made by older versions. Sometimes, however, if the code written in an older version depends on a component (bpl or something else) that is no longer supported you will get compile errors. I've converted a lot of code from version 3 to 5 and never had any problems that I couldn't fix. Like Danny have said it could be a project configuration issue so check whether your project needs some packages and all the librariries are in the project's path.

If I find out what ibsmp.lib is for I'll let you know. But I can't believe that your company buys some code and doesn't have any kind of support from the vendor. I hope you'll make it work eventually but it's a waste of time

I downloaded the enterprise version and found a copy of the file

Chris, my advice is to hire a freelance VCL expert to get it done. Looking for a header there, a component here and a missing compiler flag can take years. Normally, such software packages use a make file which contains all the necessary instructions for the compiler and linker. Trying to recover that information by means of reverse engineering can work but it's a huge waste of time and quite frustrating. So the bnest thing you can do: contact an expert from the said compnay, pay him or her a few hundred bucks to make everything work (it shouldn't take more than a couple of days at most) and document all that information so that you can use it later. Remember: very few projects are a "hello world" style self contained programs that run just by clicking "Build".
