Re: [INTERNALS-WIN] Ship PHP builds for Windows on arm64?

Hi Christoph, This subject has a particular song for me. In July, I worked to build PHP 8.4.0 for ARM64. Some libraries have been built correctly and some others needed patches. I have used an Azure VM on ARM (Ampere Altra Arm-based processor). However, this solution is not suitable for the long term due to the high cost. This is the list of actual libraries built on ARM64: build_argon2_arm64.zip build_curl_arm64.zip build_edit_arm64.zip build_ffi_arm64.zip build_freetype_arm64.zip build_glib_arm64.zip build_icu4c_arm64.zip build_ImageMagick_arm64.zip build_imap_arm64.zip build_libbzip2_arm64.zip build_libiconv_arm64.zip build_libintl_arm64.zip build_libjpeg_arm64.zip build_liblzma_arm64.zip build_libmemcached_arm64.zip build_libpng_arm64.zip build_libsodium_arm64.zip build_libssh2_arm64.zip build_libwebp_arm64.zip build_libxml2_arm64.zip build_libxpm_arm64.zip build_libxslt_arm64.zip build_libzip_arm64.zip build_mpir_arm64.zip build_nghttp2_arm64.zip build_oniguruma_arm64.zip build_openssl_arm64.zip build_pgsql_arm64.zip build_pslib_arm64.zip build_qdbm_arm64.zip build_sqlite3_arm64.zip build_zlib_arm64.zip php-8.4.0-dev-devel-vs17-arm64-NEON.zip php-8.4.0-dev-vs17-arm64-debug.zip Since I don't have to publish anything because I don't know if somebody is interested. For me, the next step is to buy a computer with an ARM64 processor and Windows 11 to install all the tools for building PHP and extensions. I'm open to discussing this project with you.

Hi all, cross-posting for reach (guess that only few read internals-win). We had a feature request the other day to ship PHP builds for Windows on arm64[1]. It seems to me that Windows on arm64 has left its infancy, and we may not want to fall too far behind in supporting that platform. We already have basic support for doing PHP builds for Windows on arm64 for a few years, but there are still two major issues: (1) The libraries on which several extensions rely are not yet available for Windows on arm64; at least the winlib-builder[2] would need to be improved in this regard, but of course, some libraries may not even support Windows on arm64 yet. (2) To my knowledge, none of the core developers has a Windows on arm64 environment available, and I presume that nobody wants to run an arm64 emulator on an x64 machine. And since there are no public GH runners for that platform (that might change in a couple of months, though[3]), we cannot actually test (let alone develop) these builds. If we ship builds with what we have now, we may get user feedback, and might be able to fix an issue or three. And we may even get some help regarding (1), so (hope dies last) we might be able to ship a full fledged PHP 8.4.0 for Windows on arm64. Therefore I suggest to make PHP 8.4 builds for Windows on arm64 available on <https://windows.php.net/>, either on the QA releases page, or on the snapshots page, but to clearly mark these as highly experimental and incomplete. Thoughts?
