Errors trying to install JCL in Delphi Alexandria

Question

I am attempting to install the JCL library into Delphi RAD Studio 11. Git placed the jcl tree in my Users directory (say C:\Users\xxx); I followed instructions and made sure I updated the modules, etc.

I then attempted to execute the install.bat file, located in the C:\Users\xxx\jcl\jcl directory. When I did that I got a message to the effect that my version of RAD Studio/Delphi does not support command line compiling. That's fine, I simply opened the JDIInstaller.bdsproj (located in the C:\Users\xxx\jcl\jcl\installer folder) with RAD Studio and built it, successfully.

I then tried running the project from within RAD Studio, but I couldn't, I got an error message telling me to shut down all running instances of Delphi. Instead, I ran the EXE file directly from the C:\Users\xxx\jcl\jcl\bin folder; it ran to completion and said the installation finished. So far, so good. I should note that the JCL installer set the BPL path to C:\Users\Public\Documents\Embarcadero\Studio\22.0\Bpl and the DCP path to C:\Users\xxx\jcl\jcl\lib\d28\win32.

The issue is this: When I then go to open RAD Studio, I get a number of messages like below. The text of the error message is:

Can't load package C:\Users\Public\Documents\Embarcadero\Studio\22.0\Bpl\JclBaseExpert280.bpl.
The specified module could not be found.
Do you want to attempt to load this package the next time a package is loaded?

This dialog is repeated an additional six times (i.e. there are a total of seven messages). The file names are as follows (they all end with "Expert280.bpl", so I'm just giving the beginning part): Debug, FavoriteFolders, ProjectAnalysis, Repository, JCLSIMDView, JCLStackTraceViewer.

If I open Components->Install Packages in the RAD Studio IDE, the seven files appear in the Design Packages list, but unchecked. They all appear as "File C:\Users\Public\Documents\Embarcadero\Studio\22.0\Bpl" followed by the specific file name.

I checked, and the files exist in that location, but I know from my research that the message can be misleading; i.e., the message is returned by Windows which may be looking for a support file.

I don't know where to go from here.

I should note that previously I attempted to install JCL/JVCL into RAD Studio 2010 and initially got the same error message, but solved it by using a more recent version of JCL. However, there IS no more recent version of JCL that I can find.

Of course, it may be this cannot be done; i.e. install JCL/JVCL into Alexandria. Any information whether this is the case and, if not, what I might try would be appreciated.

Answer 1

The RAD install this time is into a folder marked 22.0 as against last times 21.0. Before trying to install JCL and JVCL I renamed all folders 21xx to kill the links (in Documents\embarcadero\studio C:\users\public\documents\embarcadero\studio C:\Program Files (x86)\Embarcadero\Studio). Also did the same in Registry. When I tried to install again it all worked.. Best of luck

Just to add - trying to use Jedi with Alexandria and windows 10. With Sydney I used Getit and it worked beautifully. Alexandria hasnt got it listed which means back to the old manual method. Removed everything (I think) from the previous RAD - installed the latest JCL (daily download) - at least it tells me all was installed. Tried to compile JVCL install project but got the 7 BPL files missing errors and it wont compile. I use JV extensively so its a bit sad that installation is so naff. Any help would be truly appreciated as am incredibly ancient and this is my hobby.
