laz_xmlstreaming.pas fails to compile

[Ryan J]

I'm trying to build the Pascal Language Server which uses Lazarus CodeTools (lazutils) but after some changes were made and I've pulled the latest changes to Lazarus sources I get build errors in laz_xmlstreaming.pas.

Here is the command I'm using. What changed and how can I compile the lazutils now?

You did not specify which version of LazUtils you're using... but I'll assume you need the commit in Lazarus trunk which fixed compilation on FPC 3.3.1:

Here's the commit I'm using, from Oct 23 so quite recent. Before I updated it DID work. I'm stuck on an older version of FPC for now but does that shouldn't matter. It feels like something is out sync or I need to specify some unit path.

On GitHub (https://github.com/genericptr/pascal-language-server/issues/101) another person says he can't replicate the error but he's not on macOS so this may be macOS only. Can anyone else replicate this on their system?
