  • Glocal Forum Presentation
    GLOCAL FORUM PRESENTATION UN HABITAT EXPERT GROUP MEETING ON STRATEGIES FOR CREATING URBAN YOUTH EMPLOYMENT : Solution for Urban Youth in Africa I - Glocal Forum experience on youth and governance 1. Glocal Forum The Glocal Forum is a Non-Governmental Organization created in 2001 working for a new balance between global and local forces by emphasizing the central role of cities in the world. Our vision, glocalization, is an innovative strategy focusing on global issues by empowering local communities. It is a reform of globalization that encourages global powers to have a broader respect for local powers and cultural diversity. Led by its president, Ambassador Uri Savir, the Glocal Forum promotes peacebuilding and development activities through city-to-city relationships, youth empowerment and information communication technology. The Glocal Forum believes that cities have a central role in international relations and that mayors are poised to become the new diplomats of our world. City leaders have the advantage of mobilizing the good will, energy and expertise of their civil societies to contribute to peaceful dialogue and cultural exchange. The organization supports city-to-city networks by connecting them to the resources of the private and public sector. The Glocal Forum utilizes this global coalition of international organizations and private sector companies to harness resources and address local needs. A primary goal of city-to-city cooperation is to build an environment in which divisions caused by conflict and hatred can be bridged with harmony and coexistence. The Glocal Forum uses the city- to-city model as a fresh approach to brokering peace in the Middle East.

  • Sdruno (Extio) on Linux Using Wine 4.0 on Ubuntu 16.04 a Guide Put Together by the Community
    SDRuno (ExtIO) on Linux using Wine 4.0 on Ubuntu 16.04 A Guide Put Together by The Community The following procedure outlines the approach used to get the ExtIO version of SDRuno running under Wine within a Linux environment. This was pulled together as a result of the efforts of various individuals on the SDRplay forum and we have found that it works on Ubuntu 16.04. Please note the following: • This is for x86 platforms ONLY and will not work on ARM systems • If you have little or no experience with Linux, this is not recommended. Linux is in our view, not for the inexperienced or faint-hearted users. • This is NOT an ‘official’ SDRplay flow. We will not be providing ANY support for users who try this and have problems. We recommend that if you are having problems that you reach out via our community forum and hopefully the people that figured this out will be in a better position to advise you. • This flow also works for HDSDR. It may also work for SDR# or any other Windows applications that use the RTL_TCP interface or the ExtIO interface. • This will NOT work with the main version of SDRuno (non ExtIO version) at present, but we hope that we will be able to provide hooks in the future so that it will. • This does not diminish our commitment to develop a fully-fledged native Linux version of SDRuno as part of our cross-platform development program. This is intended to open more options for dedicated Linux users.

  • Using GNU Autotools to Manage a “Minimal Project”
    05AAL Ch 04 9/12/00 10:14 AM Page 21 4 Using GNU Autotools to Manage a “Minimal Project” This chapter describes how to manage a minimal project using the GNU Autotools. For this discussion, a minimal project refers to the smallest possible project that can still illustrate a sufficient number of principles related to using the tools. Studying a smaller project makes it easier to understand the more complex interactions between these tools when larger projects require advanced features. The example project used throughout this chapter is a fictitious command interpreter called ‘foonly’. ‘foonly’ is written in C, but like many interpreters, uses a lexical analyzer and a parser expressed using the lex and yacc tools. The package is developed to adhere to the GNU ‘Makefile’ standard, which is the default behavior for Automake. This project does not use many features of the GNU Autotools. The most note- worthy one is libraries; this package does not produce any libraries of its own, so Libtool does not feature them in this chapter. The more complex projects presented in Chapter 7, “A Small GNU Autotools Project” and Chapter 11, “A Large GNU Autotools Project” illustrate how Libtool participates in the build system. The essence of this chapter is to provide a high-level overview of the user-written files and how they interact. 4.1 User-Provided Input Files The smallest project requires the user to provide only two files. The GNU Autotools generate the remainder of the files needed to build the package are in Section 4.2, “Generated Output Files.”

It describes how to use the Starlink versions of the GNU autotools (autoconf, automake and libtool), how to build the software set from a checkout, how to add and configure new components, and acts as a reference manual for the Starlink-specific autoconf macros and Starlink automake features. It does not describe the management of the CVS repository in detail, nor any other source maintainance patterns. It should be read in conjunction with the detailed build instructions in the README file at the top of the source tree (which takes precedence over any instructions in this document, though there should be no major disagreements), and with sun248, which additionally includes platform-specific notes.
