The help says "You can use GetIt Package Manager to discover and install additional third-party software onto RAD Studio." but Indy is not available in GetItenter image description here

I dowloaded newest files from Github. I run the Fullc_Rio.bat file then opened Indy260.groupproj but when compiling I got:

[Fatal Error] Cannot compile package 'IndySystem260' which is currently required by Delphi 10.3.

    Indy is already installed in Rio during the product installation. It's an integral part of much of the RTL and FMX/VCL functionality. It's not available through GetIt because there's no need for it to be; it's already installed in all versions of Delphi. – Ken White May 06 '20 at 16:58

    @KenWhite "*It's not available through GetIt because there's no need for it to be*" - that is not why Indy is not in GetIt. The main reason is because Indy's install is a bit complicated for C++ support, which doesn't lend itself well to GetIt. Getting Indy into GetIt is actually on the todo list (https://github.com/IndySockets/Indy/issues/134). And I would not say that Indy is "an integral part of much of the RTL and FMX/VCL functionality", because it is not. SOME functionality, like DataSnap, uses Indy, but Embarcadero has been favoring their own cross-platform tech for awhile now. – Remy Lebeau May 06 '20 at 17:29

Indy comes pre-installed in every IDE version, and has been for a very long time.

However, if you want to install a newer version than what Embarcadero ships, you have to first remove the pre-installed version. This is mentioned in Indy's installation notes:

All package names are followed by X0 (where X0 is your Delphi/C++Builder/RAD Studio product version).

...

If Indy 10 is already installed, it needs to be uninstalled first:

  • Remove the pre-compiled design-time BPL files - dclIndyCoreX0.bpl and dclIndyProtocolsX0.bpl - from the IDE via the "Components > Install Packages" dialog.
  • Delete all of the existing binaries - IndySystemX0.*, (dcl)IndyCoreX0.*, and (dcl)IndyProtocolsX0.*
  • Delete any Indy 10 source files, if present.
  • Be sure to check for files in the IDE's \bin, \lib, and \source folders, \Indy subfolders, and OS system folders.

...

You can either:

  • Use the command-line FULLD#.BAT script that corresponds to your Delphi version.

  • Open the individual DPK files in the IDE and compile them, in the following order:

  1. IndySystemX0.dpk (in Lib\System)
  2. IndyCoreX0.dpk (in Lib\Core)
  3. IndyProtocolsX0.dpk (in Lib\Protocols)
  4. dclIndyCoreX0.dpk (in Lib\Core)
  5. dclIndyProtocolsX0.dpk (in Lib\Protocols)

...

Refer to the installation notes for full instructions.

UPDATE: the installation notes have been moved to Indy's GitHub repo:

  • @JoaoIshiwatari https://www.indyproject.org/2021/02/10/links-to-old-indy-website-pages-are-currently-broken/ contains a link to an archived copy of the install instructions – Remy Lebeau Mar 30 '21 at 02:27
  • Is 'Indy' the new version of what was known as Indy9 in the Delphi 7 days? – R.J. Dunnill Feb 28 '23 at 02:43

    @R.J.Dunnill yes. That was Indy version 9. Indy is now at version 10 – Remy Lebeau Feb 28 '23 at 15:38

Indy is already installed in Rio during the product installation. It's used in parts of the RTL. It's already installed in all versions of Delphi.

If you open a new VCL or FMX application, click on a form to activate the designer, and go to the component palette, and enter TId in the search box, you can find the Indy related component pages in the palette.
