I've been given a legacy Visual C++ project that I need to compile in Embarcadero RAD Studio XE7, but I have a problem with building it. For now, I have a problem with ATL libraries, which are needed for some components of the project:
I already copied all ATL files from include/atl to windows/sdk/atl
the project requires atlsafe.h. I've installed Visual Studio 2013, which has these headers, but I do understand how to use them properly. In case I copy atlsafe.h to windows/sdk/atl, I start to receive lots of errors which are related to the outdated atlbase.h. Once I replace atlbase.h, I start to receive more errors (expectedly), and so on.
Generally, the question is, how do I properly configure my C++Builder project for ATL, and where do I obtain the correct version of the headers? For example, for the boost headers, the problem was solved very easy (build proper version and add path to headers to -I directive).
Embarcadero dropped support for ATL in C++Builder XE, replacing ATL with the Delphi ActiveX framework (DAX). In order to use ATL in C++Builder projects in XE and later, you need to obtain ATL support files (headers and library binaries) from an earlier C++Builder version, you can't use the ones from Visual Studio. If you don't have access to an older C++Builder version, then you will have to forget about ATL and migrate the project to DAX instead.
