v12.2, 64-Bit Modern Compiler and 3rd party Delphi components

[David P 3]

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]

The answer requires all Delphi components to also be compiled with the 64-bit Modern compiler (usually to a 64x directory)

For the benefit of me and other interested parties can you expand on this please? 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:

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.

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.

Yes, you can compile them of course. 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.

Thanks @David P. 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.

I know DevExpress is hoping to deliver their components 'ready to go' for the new C++Builder tool chain.

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!
