Description

The GUI library has been renamed from Lazarus Component Library (LCL) to Pxx Component Library (PCL) to avoid naming confusion with Lazarus. The library units under lib/ have been relocated from lib/lcl/ to lib/pcl/.

Currently, the compiler has hardcoded paths to search lib/lcl/ for fallback library units (specifically in compiler/parser.inc around lines 9518, 9525, 9604, 9607). These should be updated to search lib/pcl/ instead of lib/lcl/.

Affected Files in Compiler

In compiler/parser.inc:

• Line 9518: Update default lcldir fallback path string from 'lib/lcl/' to 'lib/pcl/'.
• Line 9525: Update lcldir assembly logic from '../lib/lcl/' to '../lib/pcl/'.
• Lines 9604, 9607: Update CWD-relative search fallbacks from 'lib/lcl/' to 'lib/pcl/'.

Done Criteria

• The compiler uses lib/pcl/ as the default directory for PCL/GUI units instead of lib/lcl/.
• Building a GUI program (e.g. test/gui/test_pcl_window.pas) compiles successfully without needing explicit -Fulib/pcl/ search flags, using default compiler resolution.

Log

• 2026-06-20 — Opened during Track B renaming of LCL to PCL.

DONE 2026-06-20 (commit f9e0069)

Updated the 4 default unit-search fallbacks in parser.inc from lib/lcl/ to lib/pcl/ (+ the ExeDir-relative ../lib/pcl/ and the two CWD-relative .pas/.pp fallbacks, + comments). GUI programs now resolve PCL units without an explicit -Fulib/pcl. (lib/lcl no longer exists — Track B's rename landed.) x86-64 self-host byte-identical.
