Reiner,
the error "cpl_cpu_features.cpp(69): error C3861: "CPL_CPUID":"
indicates that the compiler goes into a code path that is protected by a
#if defined(HAVE_SSE_AT_COMPILE_TIME).
This HAVE_SSE_AT_COMPILE_TIME macro is set in gdal.cmake when
"${CMAKE_SYSTEM_PROCESSOR}" MATCHES "(x86|AMD64)" .
So I believe there's a misconfiguration of your CMake cross compilation.
Try adding -DCMAKE_SYSTEM_PROCESSOR=ARM64 perhaps. Although
https://cmake.org/cmake/help/latest/variable/CMAKE_SYSTEM_PROCESSOR.html
suggest you should likely rather use a proper CMAKE_TOOLCHAIN_FILE to
set all variables correctly.

Hi,
I am trying to compile the GDAL library for the Windows ARM64
architecture but fail during the build step because of undefined
CPL_CPUID in the port\cpl_cpu_features.cpp file. The Windows ARM64
case seems not to be covered in the definition block at the top.
Can you please give advice on how to fix this issue, or can you please
get me into contact with people working on creating GDAL binaries for
Windows ARM64. If GDAL binaries for Windows ARM64 already exist,
please point me to the download location. Thank you very much in advance.
Here are details on what I have done:
* The GDAL source was downloaded from the master branch at
https://github.com/OSGeo/GDAL.
* CMAKE configuration command: cmake -DCMAKE_PREFIX_PATH=c:/develop
-DBUILD_APPS=OFF -DGDAL_BUILD_OPTIONAL_DRIVERS=OFF
-DOGR_BUILD_OPTIONAL_DRIVERS=OFF -DCMAKE_BUILD_TYPE=Release ..
* CMAKE build command: cmake --build .
The output from the config and build steps are attached. Dependencies,
such as proj, hdf5, netcdf, sqlite3, expat, openssl, zlib and others
had been compiled successfully previously and are accessible at
compile time at C:\develop. I am working on a Windows on Arm system
with Snapdragon(R) X Elite processor and 32GB of RAM.
Any advice on how to make progress is greatly appreciated. Thanks in
advance.
Best regards,
Reiner Schlitzer
