Matreshka's User's Guide

Installation

To install Matreshka unpack its source code archive and run

make
make install

Automatic configuration utility will be build and run to configure Matreshka to meet your machine and operating system.

On Windows system you need 'make', 'install' and a few other commands. The easiest way to get them is to install Make and CoreUtils packages from GnuWin32 port. Another option - install MinGW or Cygwin environment.

Advanced installation

Sometimes, it is needed to have more control over configuration and build of Matreshka. One example is use Matreshka on Windows, where detection of non-standard libraries is problematic. Another example is binary packages supporters.

So, build of Matreshka consists from several steps:

  • build of configuration utility;
  • execution of configuration utility;
  • build of package;
  • installation of package.

Build of configuration utility

Configuration utility can be build by using

make config

Execution of configuration utility

Execution of configuration utility in its simplest form looks like:

./configure

This is exactly what default make target do, so there is no reasons to use it.

Configuration utility allows to specify several additional parameters all of is reported by

./configure --help

Below is small example of manual execution of configuration utility to install Matreshka in specified directory and to lookup SQLite's libraries in the specified directory on Windows:

configure.exe --prefix=C:\Matreshka --with-sqlite3-libdir=C:\Matreshka\lib

Build of Matreshka

To build Matreshka after manual configuration it is sufficient to run

make

Several make's variables can be used to adjust build process:

  • SMP_MFLAGS can be used to utilize several CPUs to compile Matreshka;
  • GNAT_OPTFLAGS can be used to pass additional user defined switches for compiler.

Installation of Matreshka

And to install Matreshka:

make install

Install target is used DESTDIR environment variable to adjust root directory, it is very useful for binary packages supporters.

Debugging of appications

Matreshka provides GDB plugin to pretty printing of provided data types: you will see textual representation of actual data instead of content of internal data structures.

Setup of plugin for GDB

You need to copy gdb/python/matreshka.py file to somewhere in you file tree and add line to load this file into .gdbinit file:

source <path>/matreshka.py

Next time you run GDB it will load plugin to pretty print Matreshka's data types. Note, due to GDB architecture this works only on objects of Matreshka's datatypes, not on user defined record or array types. Thus, if you debugging following code:

   type Person is record
      Name : League.Strings.Universal_String;
   end record;

   Obj : Person;

the only way to print value of Obj.Name is to use

print Obj.Name
