Unable to build libde265 on ARM64 macOS

[mpociot]

Hey!

I am trying to build PHP 8.5 (also fails on 8.4) but get an error with libde265 in my GitHub action workflow.

Operating System: macOS 14.8.5 (also fails on 15.x)
GitHub Image: macos-14-arm64
GitHub Image Version: 20260413.0223.1
Extension list:

intl,pdo_sqlite,sqlite3,curl,openssl,tokenizer,bcmath,bz2,calendar,dba,ftp,iconv,mysqli,mbstring,mbregex,xml,simplexml,ctype,dom,pdo,filter,session,zlib,fileinfo,pdo_mysql,posix,sockets,shmop,sodium,sysvmsg,sysvsem,sysvshm,gd,zip,gmp,redis,xmlwriter,phar,exif,xmlreader,readline,pcntl,soap,imagick,ffi,password-argon2,pgsql,pdo_pgsql,imap,ldap,xsl,igbinary,zstd,gettext,mongodb,sqlsrv,pdo_sqlsrv,opcache

Error from log: https://gist.github.com/mpociot/aacdaaa81cd6e73760007527a09aafff

Reproduced with the latest nightly and stable build of static-php-cli.

I was able to fix this (with the help of AI) by modifying macos/library/libde265.php and add:

'-DHAVE_ARM=OFF'

But I'm not sure if this is really the right way to prevent this from happening.

It seems libde265 is incorrectly using 32-bit ARM assembly, which offers no benefit for static PHP and should indeed be disabled.

However, I cannot reproduce this locally, I could submit a PR to disable it if this resolves your issue.

For now it is, for v3 we'll work in a better way to use correct intrinsic support levels.
