Gem #65: gprbuild Author: Emmanuel Briot, AdaCore Abstract: gprbuild is a new program builder, superseding gnatmake. It supports multiple languages, automatically manages source dependencies, and reduces the need for recompilation. This Gem describes a high-level view of how gprbuild works. Let s get started ¦ GNAT allows for a great deal of flexibility in compiling applications. The traditional method is to use gnatmake on the command line, specifying the list of source directories by using -I switches, and letting gnatmake decide which files need to be recompiled. One drawback of this approach is that it only works for Ada files. If your application uses sources written in other languages (which is probably the case for the majority of serious applications), then you need some kind of wrapper around gnatmake. This is typically done via a Makefile: first you recompile C, C++, and other source files using standard Makefile techniques, then invoke gnatmake to handle the Ada sources, and finally (although this can also be done as part of gnatmake) bind and link your application. Gnatmake is what we call a builder. Its role is to examine all source files in your application and decide which ones need
