David P 3 Posted September 16 When testing BCB v12.2 I place one third-party component on a form and compile for 32-bit and 64-bit with no issues. When compling with the 64-Bit (Modern) compiler I receive the following error: [ld.lld Error] ld.lld: error: unknown file type: HTMLabel.o Do Delphi 3rd-party components need any special compilation to work with the 64-bit (Modern) compiler?

David P 3 Posted September 17 The answer requires all Delphi components to also be compiled with the 64-bit Modern compiler (usually to a 64x directory) Share this post Link to post

Delphi components implies they are written in Delphi. You can't compile these with any of the C++ compilers..... So what exactly did you do that made the third party component work in your case ?

Actually, you can. Let me quote @Remy Lebeau from another thread: Quote C++Builder has always included the ability to compile Delphi .pas files that are added to C++ projects. As an example, see the C++ Builder packages of VirtualTreeView. Edited September 18 by Uwe Raabe Share this post Link to post
David P 3 Posted September 18 Hello Roger We have a copy of RADStudio so it was an easy job to compile any Delphi components. For the components where we have the source (Delphi or C++), we needed to add an additional 'Target Platform' of 'Windows 64-Bit (Modern) '. Using the macro $(Platform) in the output path will create a \Win64x output directory. For those Delphi components for which we do not have source code, we'll just have to wait for an update from the vendors. 1 Share this post Link to post

But not with the clang C++ compiler. Under the hood the C++ Builder (or RAD Studio) uses the pascal / delphi compiler to compile the *.pas files. Share this post Link to post

Yes, you do need to recompile with the \win64x output directory. All is good now - thank you for your extra explanation. Thanks too to @Uwe Raabefor his help / clarification.

weirdo12 20 Posted September 18 (edited) I know DevExpress is hoping to deliver their components 'ready to go' for the new C++Builder tool chain. https://community.devexpress.com/blogs/vcl/archive/2024/07/24/vcl-year-end-roadmap-v24-2.aspx Quote We expect to support modern C++ compiler-related features in our v24.2 release cycle. For technical information in this regard, please review the following: second Behind the Build webinar and documentation on upgrading with key things to know.

weirdo12 20 Posted September 19 I know we are just lucky to be able to use C++ when building apps using the super powers of the VCL but it's so nice to have C++ specific stuff like Visual Assist added to the product! Share this post Link to post
