Somehow creating a 64bit DLL with Borland C++ Builder?

I've created a 32bit DLL in Borland C++ Builder XE2 no problem.

I was tasked to create a 64bit version as well. After researching the "hows" I came to know that Builder does not yet support 64bit compilations.

After some digging around it looked as though the only way to do this ( or any kind of 64bit compiling) was to use visual studio express command lines. Thus I tried the following commands to try to compile:

CALL "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.Cmd" /x64
"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64\cl.exe" -IC:\projects\dll -I"C:\Program Files (x86)\Embarcadero\RAD Studio\9.0\include\windows\vcl" -I"C:\Program Files (x86)\Embarcadero\RAD Studio\9.0\include\windows\rtl" -MD -LD C:\projects\dll\dll.cpp -FeMyDLL.dll

Open in new window


Running the above gives me the following error:

C:\Program Files (x86)\Embarcadero\RAD Studio\9.0\include\windows\rtl\sysmac.h(162) : fatal error C1189: #error : "System.hpp/sysmac.h and related headers need __declspec(uuid(..)) and __uuidof support"

Open in new window


Mucking about on Google only gave me some posts on adding #define DECLSPEC_UUID(guid) which doesn't help at all.

So my question is, has anyone ever successfully compiled a borland c++ project (or an application / dll created in borland) for 64 bit (plus a step-by-step on how)? Or if anyone can help with the above error message, it would be greatly appreciated.

I found a hint for you in the RAD Studio XE2 help.  Bring up the help and place this in the URL:

ms-help://embarcadero.rs_xe2/rad/The_declspec_Keyword_Extension.html

Towards the bottom it gives an explanation of the declspec as it applies to using a GUID with a COM style object being defined in a DLL.  

If you need to define one, just hit [Ctrl][Shift][G] and it will create the statement for you.  Placing this near the top of your project file should give you the ID it is looking for.

I post this as an attempt to help you out.  I use Delphi XE2 as the syntax is FAR more readable than the C++ is.  Having stated that, it has been many years since I compiled anything in C++, so I cannot give you a step by step.

There is no answer to this question. After being in touch with borland themselves it seems as though 64 bit support *might* only be supported in c++ from XE3.
