Hello,
I'm digging up this subject, to find out if it has evolved since its creation.
I tried to install the jcl.lpk package proposed by fcpdeluxe ==> impossible to compile (and I'm not asking for help with that).
I looked in the GitHub forks of the original jcl: a lot, and I fully realize the enormity of the work to make all this code sometimes written since a very long time, compatible with Delphi and with Free Pascal, but I have find many beginning of conversions all fragmented (that still has the merit of existing, and I realize well the enormity of the work).
Basically, the original jcl resonates with compilation instructions according to this or that version of its Delphi's compiler. On the other hand, Free Pascal often defines a huge test "{else Ifdefine fpc}..." and rewrites its code, using sub-directives by presence of features in the compiler.
My question is: is there an official Free Pascal GitHub, where the jcl would be rewritten with only a Free Pascal orientation, regardless of Delphi's compiler versions?
As it stands, otherwise, I would just copy and paste bits of jcl code that interest me, in my units (like many, each on its own side

...).
