can't install php agent in Alpine Linux 3.18

[woniuzhang]

Install php agent according to https://skywalking.apache.org/docs/skywalking-php/next/en/setup/service-agent/php-agent/readme/ , I tried pecl and source code to install , they all make the same error.
I had successed install in alpine 3.21 and php 8.4.1

But Install in the same way as in alpine 3.18 and PHP 8.2.7, it failed.

The error messages you provided are useless, and I had no problem compiling it inside a php:8.2-alpine3.21 container.

Check if you might have missed any dependencies or settings, like the one mentioned in the documentation: export RUSTFLAGS="-C target-feature=-crt-static".

[woniuzhang]

I had set RUSTFLAGS, alpine version is 3.18 not 3.21
RUN echo "http://dl-cdn.alpinelinux.org/alpine/edge/main" >> /etc/apk/repositories && \ apk add autoconf git wget protoc cargo && \ apk add gcc make musl-dev llvm15-dev clang15-dev protobuf-c-compiler && \ export RUSTFLAGS="-C target-feature=-crt-static" && \ cd /tmp/ && \ git clone --recursive https://github.com/apache/skywalking-php.git && \ cd skywalking-php && \ phpize && \ ./configure && \ make && \ make install

[jmjoy]

php:8.2-alpine3.18 works just as well.

Thanks, I tried to use php:8.2-alpine3.18 works just as well, but tried to use php:8.2.7-alpine3.18 got the same error
