JCL package not compiling

[Tesla2k]

Hello,
I have installed Lazarus with fpcupdeluxe on Windows. The 32Bit Version. FPC and Lazarus both in the stable Version.
Afterwards I installed the JCL Module, but when I try to compile the Package in Lazarus I get the following errors:

JclStrings.pas(5393,10) Error: function header doesn't match the previous declaration "CompareNaturalStr(const AnsiString;const AnsiString):LongInt;"
JclStrings.pas(5398,10) Error: function header doesn't match the previous declaration "CompareNaturalText(const AnsiString;const AnsiString):LongInt;"

This is mentioned in this bug report
But the last entry is from 2013 and with the message, that there is a patch for this.

Can it be that fpcupdeluxe installs an old version or why is this issue still around?

This is not a fpcupdeluxe issue, but a JCL issue.

The latest sources contain errors. These need to be resolved upstream.
Besides, JCL cannot be used out-of-the-box. It needs to be installed.

Have a look here.
https://github.com/LongDirtyAnimAlf/FPC-USB-HID/tree/master/jcl/jcl/source
https://github.com/LongDirtyAnimAlf/FPC-USB-HID/tree/master/jedi
https://github.com/LongDirtyAnimAlf/FPC-USB-HID/tree/master/jvcl/jvcl

Closing.

Re-opening.
Will look into this issue again, due to the fact that, as you pointed out, old sources from a GitHub repo are used.

I have looked into the latest jcl sources. These still contain many errors and are (at the moment) not compatible with FPC.
Again, as this is not related to fpcupdeluxe, I will close this issue.

As of the comment here JCL and JVCL are not supposed to support FPC and Lazarus.
Maybe you can add a short note in the description of the module, that it is not officially supported and may not work. So everybody is prewarned.

The above was also the reasoning for not using the upstream JCL, but the (older) JCL that was guaranteed to build with FPC.
However, its not that hard to have a compatible upstream JCL. If time permits, will look into forking.
