Resources to help you move your Delphi and C++Builder Win32 projects to Win64

Posted by on in Tips, Tricks and Techniques

Stephen Ball recently posted a blog with information and resource links to help Delphi developers move their 32-bit Windows projects to 64-bit Windows. I also provided C++Builder resource links for those C++ developers that want to move their 32-bit Windows projects to the new C++11 compiler and also want to migrate their 32-bit apps to 64-bit Windows. Here are the links that will help you move forward.

Updating 32-bit code to Delphi 64-bit by Stephen Ball

On the whole moving to 64bit (on iOS or Windows) is beautifully simple to achieve! It can be just as simple as adding the Delphi 64bit Windows target platform in the project manager and rebuilding the project. A lot has been recorded on moving from Windows 32bit to Windows 64bit Delphi and this blog post gives you a useful summary if your just planning now moving up from older versions of Delphi to Delphi 10.

Updating C++Builder 32-bit projects to 64-bit

For C++Builder users looking to upgrade your apps from 32-bit to 64-bit we have documentation available on our docwiki

Bruneau Babet, a member of our C++ compiler team, did a CodeRage 7 C++ session about migrating 32-bit to 64-bit Windows applications.

I also have a blog post that goes over some of the language extensions we made to the C++Builder 64-bit compiler. You can find that blog post at
