Addresses reported flickering and rendering problems on ARM64 devices running Windows 11 25H2 by implementing ARM64-specific rendering defaults, build configuration fixes, and redraw optimizations. Rendering fixes: - Default to SC_TECHNOLOGY_DIRECTWRITERETAIN on ARM64 to preserve back buffer between frames, avoiding blank flashes with Qualcomm Adreno GPUs and Win11 25H2 DWM compositor changes - Wrap MsgThemeChanged() in WM_SETREDRAW FALSE/TRUE to suppress N intermediate repaints during heavy theme/DPI transitions - Add WS_EX_COMPOSITED to main window on ARM64 for system-level double-buffering - Remove RDW_ERASE from DarkMode ListView/TreeView RedrawWindow() calls to avoid background erase flash during theme changes Build configuration fixes: - Add _WIN64 preprocessor define to Scintilla, SciLexer, Lexilla ARM64 configurations (was missing, could cause 32-bit code paths) - Add TargetMachine=MachineARM64 to all ARM64 linker sections across Notepad3, Scintilla, SciLexer, Lexilla projects - Add CETCompat=false to Scintilla and SciLexer ARM64 configurations (CET is x86/x64 only, not compatible with ARM64) Platform code improvements: - Add _M_ARM64 detection for GrepWin binary selection (ARM64 was silently mapped to x64 binary via _WIN64 check) - Add NP3_BUILD_ARM64 helper macro in TypeDefs.h for future ARM64-specific code paths - Document RenderingTechnology setting in Build/Notepad3.ini with per-resolution override syntax and ARM64 troubleshooting tips Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |

README for building of Scintilla, Lexilla, and SciTE
Scintilla and Lexilla can be built by themselves.
To build SciTE, Scintilla and Lexilla should first be built.
See lexilla/README for information on building Lexilla.
*** GTK+/Linux version ***
You must first have GTK+ 2.24 or later and GCC (7.1 or better) installed.
Clang may be used by adding CLANG=1 to the make command line.
Other C++ compilers may work but may require tweaking the make file.
Either GTK+ 2.x or 3.x may be used with 2.x the default and 3.x
chosen with the make argument GTK3=1.
To build Scintilla, use the makefile located in the scintilla/gtk directory
cd scintilla/gtk
make
cd ../..
To build and install SciTE, use the makefile located in the scite/gtk directory
cd scite/gtk
make
sudo make install
This installs SciTE into $prefix/bin. The value of $prefix is determined from
the location of Gnome if it is installed. This is usually /usr if installed
with Linux or /usr/local if built from source. If Gnome is not installed
/usr/bin is used as the prefix. The prefix can be overridden on the command
line like "make prefix=/opt" but the same value should be used for both make
and make install as this location is compiled into the executable. The global
properties file is installed at $prefix/share/scite/SciTEGlobal.properties.
The language specific properties files are also installed into this directory.
To remove SciTE
sudo make uninstall
To clean the object files which may be needed to change $prefix
make clean
The current make file supports static and dynamic linking between SciTE, Scintilla, and Lexilla.
*** Windows version ***
A C++ 17 compiler is required.
Visual Studio 2019 is the development system used for most development
although Mingw-w64 9.2 is also supported.
To build Scintilla, make in the scintilla/win32 directory
cd scintilla\win32
GCC: mingw32-make
Visual C++: nmake -f scintilla.mak
cd ..\..
To build SciTE, use the makefiles located in the scite/win32 directory
cd scite\win32
GCC: mingw32-make
Visual C++: nmake -f scite.mak
An executable SciTE will now be in scite/bin.
*** GTK+/Windows version ***
Mingw-w64 is known to work. Other compilers will probably not work.
Only Scintilla will build with GTK+ on Windows. SciTE will not work.
Make builds both a static library version of Scintilla with lexers (scintilla.a) and
a shared library without lexers (libscintilla.so or libscintilla.dll).
To build Scintilla, make in the scintilla/gtk directory
cd scintilla\gtk
mingw32-make
*** macOS Cocoa version ***
Xcode 9.2 or later may be used to build Scintilla on macOS.
There is no open source version of SciTE for macOS but there is a commercial
version available through the App Store.
To build Scintilla, run xcodebuild in the scintilla/cocoa/ScintillaFramework or
scintilla/cocoa/Scintilla directory
cd cocoa/Scintilla
xcodebuild
*** Qt version ***
See the qt/README file to build Scintilla with Qt.
