This is a preliminary ARM64 platform support for wxWidgets at "it
compiles" stage. This will allow building and testing wxWidgets based
apps for oncoming Windows 10 ARM64.
Requirements:
- Visual Studio 2017 Update 4 or later with Visual C++ compilers and
libraries for ARM64 component installed
Building:
1. Open command prompt.
2. Change directory to build\msw subfolder.
3. Run "C:\Program Files (x86)\Microsoft Visual
Studio\2017\Community\VC\Auxiliary\Build\vcvarsamd64_arm64.bat" once.
4. Use `nmake TARGET_CPU=ARM64 ...` to build required flavor of wxWidget
libraries.
Notes:
1. Building of *.sln/*.vcxproj files does not support ARM64 yet. This
requires to hardcode Windows SDK to 10.0.15063.0 or later in
*.vcxproj files, which would render them non-compilable in older
Visual Studio versions. Microsoft is aware of this issue and is
planning a fix in the next version of Visual Studio.
2. wxmsw31ud_gl.dll does not build yet. Awaiting Microsoft to deliver
missing opengl32.lib for ARM64. Please, specify USE_OPENGL=0.
