Hi Even,
thanks for your help. I have solved my problem and have successfully built the
GDAL library for Windows ARM64. The cause was a second CMAKE installation as
part of StrawberryPerl, which currently is only available as x64 package.
Uninstalling StrawberryPerl and using the CMAKE within Visual Studio solved the
problem. Thanks again for your prompt responses.
Best regards,
Reiner

Betreff: Re: [gdal-dev] compiling gdal from source for Windows ARM64 failed
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:
1. The GDAL source was downloaded from the master branch at
https://github.com/OSGeo/GDAL.
2. 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 ..
3. 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
