I built a new project for C++ Builder 12.1 by copying everything from my 11.3 project. It has not successfully linked yet. These are the last messages. [ld.lld Warning] ld.lld: warning: duplicate symbol: vtable for __cxxabiv1::__class_type_info [ld.lld Error] ld.lld: error: undefined symbol: FMXmain It does not and has never used Fire Monkey.

The message [ld.lld Error] ld.lld: error: undefined symbol: FMXmain will appear if a projects source file is deleted, or closed if it hadn't been saved. I have accidentally discovered this while using a small console application. It did not use Fire Monkey.

You want sum+=x;

I have made another project from scratch with success apart from the same linker warning.

I created a project to match the previous one. It has not completed linking. The source files have not moved. I think there is a bug with Builder since it shouldn't have anything to do with FMXmain. It is a DLL project with VCL. I have similarly converted some other projects that are static libraries.

With 12.1 DllMain has been changed to _libmain. It also has a different signature to DllEntryPoint. extern "C" int _libmain(unsigned long reason) { return 1; }

I think it is saying 5 hours and some minutes. Does anyone else have trouble with GetIt servers today?

I started a new static LIB project on C++ Builder 12.1. In Project Option, Project Properties, General where has 'Run C++ compiler in a separate process' gone? Also where is 'Number of subprocesses'? When I built the LIB I had the message unknown argument --jobs=1, which is related to the missing options.

With the 12.1 64-bit modern compiler the include directory windows\crtl is omitted. I am assuming it has problems that could not be resolved for that verion of C++ Builder. Is this fixed with 12.2? Is there any way to use gettime and getdate of the header dos.h with 12.1 64-bit modern?

I have noticed the option 'Run C++ compiler in a separate process' with 12.1 that should not be seen will occasionally appear.

When I compile a unit for Windows 64-bit Modern with 'Enable all warnings' on and get many warnings and hints the dialog box says there are 0 warnings and 0 hints.

I am getting some compiling done now. Is per file overrides set by right clicking on a project file and selecting edit local options? I haven't looked at this before.

Is there any way to remove the arguments?

I have found that the parallel processing feature is removed with 12.1 Clang 64 modern and is brought back and enhanced with 12.2. I also have a message about an unknown argument -PD. I don't feel that 12.1 was tested before release with static library projects.

Some of these suggestions don't apply to C++ Builder.

I am using C++ Builder 11. alignas does not see,m to fully implemented. It is a C++11 feature so it isn't that new. This code produces an error saying alignas cannot be applied to types. It does seem to be valid code. template < typename T > struct CreateStatic { static T* Create() { static char alignas(std::max_align_t) staticMemory_[sizeof(T)] ; return new (&staticMemory_) T; } static void Destroy(T* const p) { p->~T(); } };

That is the bug, thanks. alignas does compile with the classic compiler so that list could be incomplete.

I have installed a trial of C++ Builder 12.1. The bug is still present with Clang 15.

I don't use the classic compiler. I can compile all of the unit this is in with the classic compiler and it has some code of C++11 and later. I think you said somewhere it only supports C++03 but I am not seeing that. The message is 'alaignas' attribute cannot be applied to types. Taken literally that doesn't make sense. An alias declaration can have it and they have types. alignas(T) is an improvement to the original code.

The startup script errors seem to have stopped.

If I make a small console application without saving it I can build and run it once. Than I get [ilink32 Error] Fatal: Could not open .\Win32\Debug\Project1.exe (error code 1224). This always happens now with Builder 11.3. If I use the Clean option I get [Delete Error] Unable to delete file ".\Win32\Debug\Project1.exe". Access to the path 'C:\Users\Fraser Ross\Documents\Embarcadero\Studio\Projects\Win32\Debug\Project1.exe' is denied.

I've been told it will be fixed in the next version.

I appear to have solved this by shutting down Webroot SecureAnywhere and restarting it.

The file appears to remain open in C++ Builder. Even after closing the IDE it is still open.

I have tried to install the newly available community edition which is 11.0. The Embarcadero site tells me: Your download should begin immediately for C++Builder Community Edition 11.3 Alexandria installer. My serial number does not seem to be matching to the installed software. It says something about Delphi which is another incorrect thing when I try to register. Has someone made a complete mess of things? My e-mail with the serial number gives a link to an installation program for 11.3 : RADStudio_11_3_esd_28_13236.exe
