This release contains numerous bug fixes, and also the
following new features:

  * The GNU Binutils sources now requires a C99 compiler and library to
    build.

  * Support for the arm-symbianelf format has been removed.

  * Support for Realm Management Extension (RME) for AArch64 has been
    added.

  * A new linker option '-z report-relative-reloc' for x86 ELF targets
    has been added to report dynamic relative relocations.

  * A new linker option '-z start-stop-gc' has been added to disable
    special treatment of __start_*/__stop_* references when
    --gc-sections.

  * A new linker options '-Bno-symbolic' has been added which will
    cancel the '-Bsymbolic' and '-Bsymbolic-functions' options.

  * The readelf tool has a new command line option which can be used to
    specify how the numeric values of symbols are reported.
    --sym-base=0|8|10|16 tells readelf to display the values in base 8,
    base 10 or base 16.  A sym base of 0 represents the default action
    of displaying values under 10000 in base 10 and values above that in
    base 16.

  * A new format has been added to the nm program.  Specifying
    '--format=just-symbols' (or just using -j) will tell the program to
    only display symbol names and nothing else.

  * A new command line option '--keep-section-symbols' has been added to
    objcopy and strip.  This stops the removal of unused section symbols
    when the file is copied.  Removing these symbols saves space, but
    sometimes they are needed by other tools.

  * The '--weaken', '--weaken-symbol' and '--weaken-symbols' options
    supported by objcopy now make undefined symbols weak on targets that
    support weak symbols. 

  * Readelf and objdump can now display and use the contents of .debug_sup
    sections.

  * Readelf and objdump will now follow links to separate debug info
    files by default.  This behaviour can be stopped via the use of the
    new '-wN' or '--debug-dump=no-follow-links' options for readelf and
    the '-WN' or '--dwarf=no-follow-links' options for objdump.  Also
    the old behaviour can be restored by the use of the
    '--enable-follow-debug-links=no' configure time option.

    The semantics of the =follow-links option have also been slightly
    changed.  When enabled, the option allows for the loading of symbol
    tables and string tables from the separate files which can be used
    to enhance the information displayed when dumping other sections,
    but it does not automatically imply that information from the
    separate files should be displayed.

    If other debug section display options are also enabled (eg
    '--debug-dump=info') then the contents of matching sections in both
    the main file and the separate debuginfo file *will* be displayed.
    This is because in most cases the debug section will only be present
    in one of the files.

    If however non-debug section display options are enabled (eg
    '--sections') then the contents of matching parts of the separate
    debuginfo file will *not* be displayed.  This is because in most
    cases the user probably only wanted to load the symbol information
    from the separate debuginfo file.  In order to change this behaviour
    a new command line option --process-links can be used.  This will
    allow di0pslay options to applied to both the main file and any
    separate debuginfo files.

  * Nm has a new command line option: '--quiet'.  This suppresses "no
    symbols" diagnostic.

Our thanks go out to all of the binutils contributors, past and
present, for helping to make this release possible.

Cheers
  Nick Clifton
  Chief Binutils Maintainer

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
