缺 linux-headers 头文件吧

@jingjingxyk

Package kernel-headers-5.14.0-284.30.1.el9_2.aarch64 is already installed.

Is this a bug with aarch64-linux-musl too, or just the gcc wrapper?

It seems that it only fails to compile on AlmaLinux-aarch64. It works fine on both alpine and debian of my arm64 architecture.

[DubbleClick]

I meant if it also happened when you build musl-cross-compile (TARGET=aarch64-linux-musl) and then use aarch64-linux-musl to compile php-fpm. I don't have an ARM64 machine, so I cannot test this. :/

I finally tested on clean debian 12 arm64 platform and use spc doctor --auto-fix, got the same error:

[DubbleClick]

I can't see the configure command so I don't know if that's musl-gcc wrapper or aarch64-linux-musl compiler.

Maybe I will rent an aarch64 VM to test this.

[crazywhalecc]

@DubbleClick I uploaded the entire php-src and found no useful information so far.

php-src.tar.bz2.zip

GitHub only allows me to upload files smaller than 25MB, and not in bz2 format, so I can only compress it again.

[DubbleClick]

It's musl-gcc wrapper. Can you try with the cplusplus branch at https://github.com/crazywhalecc/static-php-cli/pull/214? It contains a lot of fixes and might just implicitly tackle this too. It seems to be missing various system headers, but compiling gcc with musl-cross-make will produce new ones.

/usr/bin/ld: /tmp/ccAzYpTF.o: in function `main':
conftest.c:(.text+0x8): undefined reference to `__dns_search

and I remember something about dns problems with aarch64/gcc for static builds.

Either way I will see to get access to an arm64 system that I can test on next week.

I spun up an arm64 almalinux (minimal) vm, installed php, composer and zip, copied spc over, ran spc doctor -> spc build snappy and it worked.

@DubbleClick How did you install musl? I used the doctor from the default branch.

[DubbleClick]

From the c++ branch pull request (#214 ) it worked right away. I didn't do extensive testing yet because imap fails with an error that makes little sense, but compiling the list of default extensions worked fine.

[crazywhalecc]

I don't have much free time this week and may not be able to work on it. I'll be diving into it over the weekend and next week.

[DubbleClick]

No problem, I will be able to get Alpine support done this week so all that's left will be MacOS support.
