LHelp crash (Mojave)

[rufusROFLpunch]

I've been attemping to get help working. I've installed the help files (both the manual method and through fpcupdeluxe). The IDE seems to be working fine otherwise, but when I attempt to load the online help the LHelp application goes into a spinning wheel of death and after a few seconds Lazarus crashes completely.

Here are the relevant lines from the logs.

Anyone have any clues about how to resolve this?

Do you actually have the lazarus .chm help files? My /Users/trev/lazarus-src/docs/chm directory is empty.

I moved in to the /Users/trev/lazarus-src/docs/html directory and found a script to compile a Lazarus program to generate the .chm files. The script fails with:

Code: [Select]

Error: (lazarus) invalid Lazarus directory "/Developer/lazarus/": directory not found
Error: (lazarus) Building failed: build_lcl_docs.lpi
So I opened the project in Lazarus and successfully compiled build_lcl_docs. Unfortunately though, running build_lcl_docs generates... an error:

Code: [Select]

1. The directory ../../chm/ does not exist.
2. The file rtl.xct dies not exist anywhere on my system (Lazarus trunk).
3. The directory /Users/trev/lazarus-src/docs/html/lazutils/ does exist but contains only:
   * fpdoc.css
   * inputfile.txt

Hmmmm.

BTW, LHelp opens my own .chm Windows help files without an issue.

[UPDATE]

I eventually found pre-generated help files in chm format at: https://sourceforge.net/projects/lazarus/files/Lazarus%20Documentation/Lazarus%202.0.6/

Apart from some issues with missing index files resulting in tabs with the name [Unknown] (see attached image), the context sensitive help actually works quite well with F1 under Mojave.

[Update]

Just a small issue: Exiting from help causes an access violation. See second attached image.

I do actually have the CHM files in that folder. I manually installed them. The issue seems to be when it starts the help server. It's waiting for a response from IPC which it never gets, apparently.
