I am trying to do a manual install of jcl since running Install.bat gives me the error: "This version of the product does not support command line compiling.". I tried to follow the documentation but i could not understand it.
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 C++Builder 6: source\include\jclc6.inc
For Delphi 6: source\include\jcld6.inc
For Delphi 7: source\include\jcld7.inc
For Delphi 2005: source\include\jcld9.inc
For BDS 2006 (Delphi and C++Builder): source\include\jcld10.inc
For CodeGear RAD Studio 2007 (Delphi for Win32 and C++Builder): source\include\jcld11.inc
For Delphi 2009 and C++Builder 2009: source\include\jcld12.inc

For Delphi 10.3 and C++Builder 10.3 Win64: source\include\jcld26win64.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).
I also tried to compile JclPackagesD280.groupproj but i get the error : "[dcc32 Fatal Error] jcl.inc(416): F1026 File not found: 'jcld28win32.inc'". I know it says "For manual installations, copy and adjust jcl/source/include/jcl.template.inc" but i also couldn't understand that.
Edit : I managed to compile and install jcl after all like in the image by downloading jcl from the dauly build but now when i try to do the same for jvcl i get "JvCore.dpk(41): E2202 Required package 'Jcl' not found"
I too was confused by the readme on manual installation as the custom ( for newer releases of Delphi CE ) files the readme refers to did not appear to exist in https://github.com/project-jedi/jcl/tree/master
I continued hunting around and found that the Readme does not apply to the master but it does appy to the nightly archives which can be found here, you'll find your missing 'jcld28win32.inc' and other missing files in here :-
