Preliminary note for Windows users

The build instructions for gprbuild may have a slight UNIX flavor but they can be used on Windows platforms with a full Cygwin installation. The latter makes it simpler to build gprbuild but is not required to use it.

Bootstrapping

gprbuild needs gprbuild to build... So we also provide a way to easily bootstrap if you don't already have gprbuild, provided you already have installed GNAT.

Download XML/Ada sources (from https://github.com/AdaCore/xmlada), together with the gprconfig knowledge base (from https://github.com/AdaCore/gprconfig_kb).

Run the bootstrap.sh script (written for POSIX systems) specifying the install location and the sources of XML/Ada and gprconfig_kb. The script will build and install gprbuild.

For example, to build gprbuild and install it to ./bootstrap in the current working directory, run:

$ ./bootstrap.sh --with-xmlada=../xmlada --with-kb=../gprconfig_kb --prefix=./bootstrap

For maintainers, the environment DESTDIR is honoured for staged installs, see ./bootstrap.sh -h for more.

With this bootstrapped gprbuild, you can build XML/Ada and gprbuild as documented below.

Configuring

You should first configure the build like this (if you plan to build in the source tree directly, you can omit setting the SOURCE_DIR variable):

$ make prefix=xxx SOURCE_DIR=/path/to/gprbuild/sources setup

Building and Installing

XML/Ada must be installed before building.

Building the main executables is done simply with:

$ make all

When compiling, you can choose whether you want to link statically with XML/Ada (the default), or dynamically. To compile dynamically, you should run:

$ make LIBRARY_TYPE=relocatable all

instead of the above.

Installation is done with:

$ make install

To build and install LIBGPR libraries, you can use the make targets libgpr.build and libgpr.install.

Doc & Examples

The documentation is provided in various formats in the doc subdirectory. You can also find it online.

It refers to concrete examples that are to be found in the examples subdirectory. Each example can be built easily using the simple attached Makefile:

$ make all    # build the example
$ make run    # run the executable(s)
$ make clean  # cleanup

All the examples can be built/run/cleaned using the same targets and the top level examples Makefile.
