How to properly configure Delphi packages so that components from these packages can be used in C++ Builder projects.

[dmitrybv 3]

Hello.

Embarcadero® RAD Studio 12 Version 29.0.53982.0329

I have a Delphi package with components. And I use them to create Delphi projects without any problems.
Now I need to use these components in a C++ Builder project.

 

In the

Project Options-Building-Delphi Compiler-Output – C/C++ package settings, I set the Generate all C++Builder files (including package libs) option.

When compiling the package, *.hpp files were created based on the pas files of the package.

Now I create a C++ Builder project, drop my components on the form and try to compile the project.

As a result, I get the following errors:

 

C:\Users\Public\Documents\Embarcadero\Studio\23.0\hpp\Win32\EhLib.Fmx.Types.hpp(64,13): error E4689: 'Controls' is not a class, namespace, or enumeration
c:\radstudio\23.0\include\windows\fmx\FMX.Controls.Presentation.hpp(34,10): error E6300: 'Controls' declared here

on line

typedef Fmx::Controls::TControl TWinControl;

I can't figure out what the error is.

 

Visually, the code section contains the correct text.

The FMX.Controls.hpp file contains nested namespaces
 

namespace Fmx
{
namespace Controls
{

And the text Fmx::Controls::… is a valid reference to a type in the nested namespace

namespace Fmx { namespace Controls {

Does EhLib.Fmx.Types.pas have the FMX.Controls unit in its 'interface' uses clause? Does the generated EhLib.Fmx.Type.hpp file have an #include <FMX.Controls.hpp> statement?

By default, Pascal-generated HPP headers bring their C++ namespaces into the namespace that is #include'ing the HPP file (which is usually the global scope).  So, in this case, there are two Fmx namespaces in the same scope, and the compiler ends up picking your namespace instead of FireMonkey's, which is why it can't find the Fmx::Controls namespace.

 

If you look at your HPP files, you will notice that there are 'using namespace' statements at the bottom which are wrapped in preprocessor blocks, eg:

#if !defined(DELPHIHEADER_NO_IMPLICIT_NAMESPACE_USE) && !defined(NO_USING_NAMESPACE_EHLIB_FMX_TYPE)
using namespace EhLib.Fmx.Type;
#endif
#if !defined(DELPHIHEADER_NO_IMPLICIT_NAMESPACE_USE) && !defined(NO_USING_NAMESPACE_EHLIB_FMX)
using namespace EhLib.Fmx;
#endif
#if !defined(DELPHIHEADER_NO_IMPLICIT_NAMESPACE_USE) && !defined(NO_USING_NAMESPACE_EHLIB)
using namespace EhLib;
#endif

To avoid this ambiguity, you can specify either DELPHIHEADER_NO_IMPLICIT_NAMESPACE_USE or the desired NO_USING_NAMESPACE_... conditional(s) in the "Conditional defines" section of your C++ project's settings.  Or, at least, simply #define them above the relevant #include statement(s) in your C++ code.  Alternatively, another workaround would be to add {$HPPEMIT NOUSINGNAMESPACE} to your Pascal units to avoid any 'using namespace' statements in their generated HPP files.

Is it possible to avoid such problems by simply naming pas modules "correctly"?
So far I understand that you can't use the string ".Vcl." and ".Fmx." in module names.
Are there any specific rules on how to correctly insert dots into package module names?
After all, when creating the namespaces structure based on the pas module name, the developers of Delphi and C++ Builder modeled how developers of new packages would integrate into the current tree of nested namespaces.

Yes, you can. And it works perfectly fine on the Delphi side. It is only on the C++ side that you may run into trouble, and I already explained how to work around that.

The issue is not about the dots themselves, but with the names you put in between the dots. It is your responsibility to make sure those names don't conflict. And instruct the C++ compiler how to handle them correctly if needed.
