Форк штатного пакета LazOpenGLContext (Lazarus components/opengl). Qt5/Qt6-бэкенд (glqtnativecontext.pas) использует собственный контекст настоящего QOpenGLWidget вместо ручного GLX на winId(): EGL на Wayland, GLX на X11, WGL/CGL на Windows/macOS под ws=qt6. QOpenGLWidget-наследник с paintGL-хуком живёт в маленькой C++-либе csrc/qlclglwidget.cpp (QLCLOpenGLWidget из libQt6Pas — не QOpenGLWidget, а голый QWidget под внешний GLX). Сборка: csrc/Makefile (linux/macos/windows-кросс mingw-w64/windows-native MSYS2, install, install-app) + build-msvc.bat для MSVC-Qt. Либа грузится в рантайме рядом с бинарником приложения. Бэкенды gtk2/gtk3/win32/cocoa скопированы из стока без изменений (юниты переименованы с суффиксом Ex). Детали и нюансы — в README.md. Проверено: EWSDR, спектр/водопад через GL в нативном Wayland (KDE, qt6), живой эфир QO-100. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# libqlclglwidget — QOpenGLWidget helper library for LazOpenGLContextEx
|
|
#
|
|
# Build variants:
|
|
# make / make linux native Linux build -> ../libqlclglwidget.so
|
|
# make macos native macOS build (on a Mac) -> ../libqlclglwidget.dylib
|
|
# make windows qlclglwidget.dll with a MinGW toolchain:
|
|
# * cross-build from Linux (mingw-w64), OR
|
|
# * natively on Windows with a Qt MinGW kit that has
|
|
# no pkg-config — override the variables:
|
|
# make windows MINGW_CXX=g++ \
|
|
# WIN_QT_INC=C:/Qt/6.x.x/mingw_64/include \
|
|
# WIN_QT_LIB=C:/Qt/6.x.x/mingw_64/lib
|
|
# make windows-native natively on Windows in an MSYS2 MinGW64 shell
|
|
# (uses pkg-config; auto-selected by plain `make` there)
|
|
# build-msvc.bat natively on Windows with MSVC (see the .bat file);
|
|
# required when the target Qt6/libQt6Pas is an MSVC
|
|
# build — MinGW and MSVC C++ ABIs are incompatible
|
|
#
|
|
# make install install the host-platform artifact into $(PREFIX)/lib
|
|
# (DESTDIR supported; run ldconfig yourself on Linux)
|
|
# make install-app APPDIR=/path/to/app/dir
|
|
# copy every built artifact next to the app binary
|
|
# (the Pascal loader looks there first)
|
|
# make clean
|
|
#
|
|
# Windows cross-build requirements (on the Linux build machine):
|
|
# - mingw-w64 toolchain: x86_64-w64-mingw32-g++
|
|
# - a *MinGW* build of Qt6 (headers + import libs), one of:
|
|
# * Arch AUR: mingw-w64-qt6-base (installs to /usr/x86_64-w64-mingw32)
|
|
# * MXE (https://mxe.cc) with qt6 (set MINGW_PREFIX to the MXE usr dir)
|
|
# * a Qt "MinGW" kit copied from a Windows Qt install
|
|
# (set WIN_QT_INC / WIN_QT_LIB manually)
|
|
#
|
|
# Windows native (MSYS2 MinGW64 shell) requirements:
|
|
# pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-qt6-base pkgconf make
|
|
#
|
|
# The MinGW-built DLL works only with MinGW Qt6 DLLs on the target machine,
|
|
# the MSVC-built DLL only with MSVC Qt6 DLLs (incompatible C++ ABIs).
|
|
#
|
|
# macOS notes: needs Xcode command line tools + Qt6 with pkg-config files,
|
|
# e.g. Homebrew: brew install qt pkgconf
|
|
# export PKG_CONFIG_PATH="$(brew --prefix qt)/libexec/lib/pkgconfig"
