LibGPR2 - Parser for GPR Project files

INSTALLING THIS LIBRARY

The LibGPR2 library depends on some other external libraries:

Both must be installed on the system to be able to compile LibGPR2.

The library also depends on the Knowledge Base containing information of different targets, runtimes, compilers, etc.:

To regenerate the GPR parser from the Langkit grammar the following additional external modules are required:

  • Python

  • Langkit (build directory)

CONFIGURING LibGPR2

The following variables can be used to configure the libGPR2 library:

  • prefix: Location of the installation, the default is the running GNAT installation root.

  • GPR2_BUILD: Control the build options: release (default) or debug.

  • PROCESSORS: Parallel compilation (default is 0, depends on the number of cores).

  • TARGET: For cross-compilation, auto-detected for native platforms.

  • SOURCE_DIR: For out-of-tree build.

  • GPR2KBDIR: Location of the Knowledge Base contents (by default library expects them in src/kb/gprconfig_kb).

  • ENABLE_SHARED: Enables the build of libgpr2 as a dynamic library if set to "yes". Otherwise only the static library is built.

To use the default options:

$ make setup

For example, to setup LibGPR2 to install a debug version on /opt/libgpr2:

$ make setup prefix=/opt/libgpr2 GPR2_BUILD=debug install

To point out the location of the Knowledge Base (assuming it has been checked out to /usr/share/gprconfig_kb):

$ make setup GPR2KBDIR=/usr/share/gprconfig_kb/db

BUILDING LibGPR2

To build all versions of the library (static, relocatable and static-pic) plus the associated tools use the provided Makefile:

$ make

Then, to install it:

$ make install

USING THE LIBRARY

See the LibGPR2 examples.

TESTING THE LIBRARY

To run the testsuite e3-core and e3-testsuite are required:

$ cd testsuite
$ ./testsuite.py
