This commit explores using the wasmenv toolkit to compile PHP. The configure phase works, but the make fails because setjmp is unsupported yet, see the error message below and the relevant GitHub issue at WebAssembly/WASI#490 There's a chance "make" would work if we tried a dedicated libc build: https://github.com/WebAssembly/wasi-libc/blob/main/libc-top-half/musl/include/setjmp.h I'm not sure if the final PHP build would be functional, though. Either way, building using wasi-sdk which has libc and set_jmp.h baked in would be a sensible next step: https://github.com/WebAssembly/wasi-sdk/releases 31 69.49 /root/php-src/main/setjmp.h:44:2: warning: setjmp is not yet implemented for WASI [-W#warnings] 31 69.49 #warning setjmp is not yet implemented for WASI 31 69.49 ^ 31 69.56 In file included from /root/php-src/ext/bcmath/libbcmath/src/div.c:32: 31 69.56 In file included from /root/php-src/ext/bcmath/libbcmath/src/config.h:7: 31 69.56 In file included from /root/php-src/main/php.h:35: 31 69.56 In file included from /root/php-src/Zend/zend_API.h:25: 31 69.56 In file included from /root/php-src/Zend/zend_modules.h:24: 31 69.56 In file included from /root/php-src/Zend/zend_compile.h:724: 31 69.56 /root/php-src/Zend/zend_globals.h:151:2: error: unknown type name 'jmp_buf' 31 69.56 JMP_BUF *bailout; 31 69.56 ^ 31 69.56 /root/php-src/Zend/zend_portability.h:361:18: note: expanded from macro 'JMP_BUF' 31 69.56 # define JMP_BUF jmp_buf

Closing this one. Let's look into collaborating with https://github.com/vmware-labs/webassembly-language-runtimes (see php-8.1.11) once WASI supports |
