The clang C++ compilers are very powerful, offering full support for C++ 17. Anyone who has read Bjarne Stroustrup’s “A Tour of C++” (the second edition covers C++ 17) will realise that a compiler has a very large amount of things to do as it translates source code to object code. This comes at a price. Compiling RAD Studio or C++ Builder projects using the clang compiler for any reasonably sized project takes tens of seconds (tens of minutes for a complete build of a very large project).
Jomitech produce a RAD Studio plugin called TwineCompile that can very significantly shorten compile times.
In August 2020 Embarcadero announced a bundling of TwineCompile for all customers using RAD Studio or C++ builder Enterprise or Architect with an up to date subscription package. For those who qualify this is now available under the Getit package manager in the IDE.
So if you are on Enterprise or Architect what are you waiting for ? Go “Getit” !
