Installing multiple library versions in Delphi / C++Builder - delphi

How I can install multiple versions of a library in Delphi or C++Builder? For example, I might want to be able to develop the next version of our app using the current versions of JCL and JVCL while still being able to compile the release version of our app using whatever version of JCL and JVCL were tested for that release.
Using more than one version of a library is easy with libraries like Boost, since those are just header files and library / DLL files that I can put wherever I want, and so I can simply point my project files at the appropriate library directories. However, since libraries like JCL and JVCL try to install themselves into the IDE, I'm not sure how to configure different projects to use different versions without it turning into an unmanageable hack.
(I'm still not entirely familiar with how Delphi manages components and projects - most of my experience is in C++ - so this may be part of my problem.)

We had the same problem, supporting older versions compiled with different versions of the components. Our solution was/is to use the IDE's " -r " command line option. With this switch it is possible to use different library paths and packages (at the same time). The only problem that we encountered with this approach was that some of us regularly tried to open an older project version in the wrong IDE instance.
[Old version 1.0] bds.exe -rVersion1.0
[trunk version ] bds.exe
How to setup those:
Start your IDE as you are used to it.
Install everything you need for "Version 1.0"
Close the IDE
Install all (old) packages (JCL/JVCL/...)
Start regedit.exe
Export the registry key HKCU\Software\CodeGear\BDS\5.0 to a *.reg file
Start nodepad.exe and do a search&replace in the *.reg file for "CodeGear\BDS\5.0" and replace it with "CodeGear\Version1.0\5.0"
Import the *.reg file (by double clicking it in the Windows Explorer)
Create a copy of your RAD Studio 2007 startmenu link and change the command line to include the "-rVersion1.0" key.
Now you have two IDE configurations that are equal. You can now change the IDE that doesn't use the " -r " command option to your trunk version's packages.
When you install all the packages, you must not use the default BPL and DCP directories unless the different package versions use different file names (like the JCL and JVCL do).
CodeGear\BDS\5.0 = Delphi 2007
CodeGear\BDS\6.0 = Delphi 2009
Borland\BDS\4.0 = Delphi 2006
Borland\Delphi\7.0 = Delphi 7

Delphi Jedi components manual installation

I'm using Delphi CE 10.4, and it has the DCC32.exe disabled line compilation.
I'm trying to manually install Jedi components, in the readme of JCL it says that it's needed to open and edit included file to customize options, in my case, source\include\jcld27win32.inc.
I'm starting to learn Delphi, and I didn't understand whats is it is necessary to do in this file, and didn't find videos showing a manual installation.
Someone who already installed this way could help me?
Manual Installation Although it is not recommended, a manual
installation is possible. You will have to manually configure options
for the library. That is done by modifying an included file. For each
tool you want to install the JCL in, repeat the following steps:
Open and edit included file to customize options: ... For Delphi 10.4 and C++Builder 10.4 Win32: source\include\jcld27win32.inc ...
In the IDE, open and compile package Jcl.dpk (or Jcl.bpk for C++Builder) located in a subdirectory of the "packages" directory
matching your version of the IDE. This package doesn't have to be
installed since it doesn't provide any components.
If you want to install experts, open package JclBaseExpert.dpk and compile it, then you can install all the experts you want (packages
are located in the same directory).

How to install Indy on Delphi 10.3 Rio?

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 GetIt
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 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:
IndySystemX0.dpk (in Lib\System)
IndyCoreX0.dpk (in Lib\Core)
IndyProtocolsX0.dpk (in Lib\Protocols)
dclIndyCoreX0.dpk (in Lib\Core)
dclIndyProtocolsX0.dpk (in Lib\Protocols)
...
Refer to the installation notes for full instructions.
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.

RAD Studio 10.2.3 Jedi JVCL Install Problem

I've uninstalled my RAD Studio 10.2.2 and installed 10.2.3 in my Win10 development VM. Along the way I uninstalled all the previous 3rd-party libs, including the Jedi GetIt packages, and per the instructions got rid of all the old Jedi source and DCP/DCLs. I'm attempting to install them back into 10.2.3 via GetIt. The JCL libs install fine, but when I try to install JVCL, the installation batch file hangs after compiling the installer and the VM comes to its knees. I rebooted, started taskmgr and watched as the batch file ran - it appears to go into a loop creating many instances of msgfmt. I've tried removing it all again, downloading and installing the 3.8 version myself and running the install batch file by itself, same problem; then backing up to the 3.6 version that had installed OK in 10.2.2, and it does the same thing. If I edit the batch file to skip the language-setup section, the batch file completes OK, but trying to re-run the GetIt update causes it to re-download and replace that batch file. :(
The installer does compile before the languages part of the batch file is reached, so I tried running the installer directly. I assume I'm not passing it cmd line info it needs, because it compiles the 64-bit libs fine but chokes immediately on compiling the 32-bit version of JvCore250.bpl with an unspecified compile error.
Anyone else run into this? Is a solution known?
Turns out to ultimately be a pathing problem. When multiple installations of the IDE exist on a machine (e.g. my VM has or previously had D2007, XE2 and 10.1 on it), the PATH environment variable can be too long - edit the PATH in the system to remove the old/stale paths. Then make sure that the library paths in the IDE includes $(BDSLIB)\$(PLATFORM)\release or you'll get "can't find RTL" when building the packages.
For me the problem is generated from the msgfmt.exe of dxgettext.
msgfmt.exe generates multilanguage messages, for a multilanguage support of jvcl installation.
For the specific problem of msgfmt.exe try to see this: dxgettext and Windows 10
I resolved the problem opened the install.bat file in jvcl folder, and I commented (with ::) every line where the msgfmt is executed.
Attention:
If you use getit I suppose you have to open the folder where jvcl is downloaded and search install.bat (I didn't use getit)
Instead I downloaded jvcl directly from github in my component folder, and I did what is written above in that folder.

Automatic building and installing Delphi components

So, my Delphi component is functional and working, aside few details yet to cover. What I would like is to create a setup (Inno setup) that would automatically install my component into user's Delphi/C++ Builder IDE. I presume I must use delphi command line compiler, but how?
Thank you.
Unfortunately Delphi IDE does not support automated component installation at all. IMO, that is very big problem since component architecture is so important in Delphi.
You can build your package from command line (using MSBuild or DCC) but you cannot install it to IDE. To install your package you should write your own installer that builds you package, copies compiled files and updates Windows registry. Note there is no official documentation how to write such an installer, but you can take Jedi (JVCL) installer code as an example.
There are also 3rd party tools that automate component installation, for example 'lazy builder', that may be interesting to you.
It's not too hard, just messy. You need to compile a BPL for each Delphi version that you want to target and then your installer puts this BPL into a folder of your choosing (often users,public etc). This folder location is then written as a registry key under the relevant Delphi Installed Packages node. Lo when you run Delphi your components appear as if you had used the manual install packages option.

Update DUnit on Delphi 2010

Does anyone know how to update dUnit which comes with Delphi 2010 to the latest svn source code?
Steps
Goto http://sourceforge.net/projects/dunit/
Download the zip file (currently version 9.3.0)
Unpack to a folder of your choice
Use Components|Install packages to remove the current DUnit package bpl.
Compile and install (optional) the new version. Compilation is needed only if you want to install the design time wizards or if you do not build your projects using the source. Installation is only needed if you want to use the design time wizards. Read the various doc and readme files for further instructions.
Update your environment's library path and the search paths of projects using DUnit:
take out any references to $(BDS)\source\DUnit*
put in a reference to the src subfolder of where you installed the new version
Update
The latest version on sourceforge is 9.3.0, but that is not the latest DUnit version. To get the latest DUnit version, you can go to its SVN repository: https://dunit.svn.sourceforge.net/svnroot/dunit/trunk/
The are at 9.4.0 (revision 41 according to the top of the page, version found in readme-9.4.txt and release.ini).
The sources found there do not contain any packages for Delphi versions past D7, but as mentioned in my response to Serg, these packages are for the DUnitWizards which were contributed from outside the main DUnit project. To use DUnit, you don't need these wizards. In fact, DUnit itself does not have any packages!
I think you can still use the wizards (or should I say project/unit templates) that come standard with Delphi and just make sure that your library and search paths point to the new version... In fact, I know you can, because that is what I did a couple of days ago: use the File|New|Other|Unit test| project and unit templates that come standard with the IDE, but compile against the newest sources downloaded from SVN.
You can either unregister current DUnit package by removing its key from Registry:
HKCU\Software\CodeGear\BDS\7.0\Known IDE Packages\$(BDS)\Bin\unittestide140.bpl
Then download and install the new version from any folder you want, into the IDE as you install any other IDE package.
Or you build the new version, copy the generated BPL file to $(BDS)\bin\ folder, and its .DCU files to $(BDS)\Lib\ folder, and replace $(BDS)\Source\DUnit folder with the source folder you downloaded from SVN.
