This is a proposal for cross compiling JavaFX base modules (excluding media and
webkit) for Windows AArch64 (ARM64).
Main changes:
- prismES2 native compilation is moved under IS_INCLUDE_ES2 condition
- HOST_ARCH and TARGET_ARCH are retrieved from ext.OS_ARCH and ext.TARGET_ARCH
using substitution aarch64 to arm64 and amd64 to x64
- VCARCH is set to "${HOST_ARCH}_${TARGET_ARCH}" architecture for cross
compilation. VCARCH is set to x64 for amd64 target architecture (according to
the [vcvarsall.bat
doc](https://docs.microsoft.com/en-us/cpp/build/building-on-the-command-line?view=msvc-160#developer_command_file_locations)
x64 and amd64 are interchangeable)
- arm64 rc.exe and fxc.exe execution fails on non arm64 host. The fix checks
that and falls back to host rc.exe and fxc.exe. The right way would be to use
rc.exe and fxc.exe from arm64 but I did not find a right way to run them on
host system.
I also looked which changes are required to build media module for Windows
aarch64.
The main changes could be using:
- `ARCH=arm64` for building media libs in build.gradle file
- `-MACHINE:arm64` LDFLAGS in media make files
- `msvc_build/aarch64/aarch64_include` header files for include,
`src/aarch64/win64_armasm.S` for ASM_SOURCES, `armasm64.exe` for ML in
gstreamer/projects/win/glib-lite/Makefile.glib file and corresponding include
in gstreamer/projects/win/glib-lite/Makefile.gobject file
- setting `ENABLE_SIMD_SSE2` to 0 in ColorConverter.c in the similar way how it
is done for Apple Silicon port
In this way the media is build but it is crashed when I run a JavaFX sample
with video.
Is it possible to send the media Windows aarch64 port to review and investigate
the crash in the separate fix?
