Describe the bug

pecl install <package> fails on PHP 8.3.

To Reproduce

On a clean Ubuntu 22.04 install with software-properties-common installed (I used ubuntu:2204 Docker image):

add-apt-repository -y ppa:ondrej/php
apt-get install -y php8.3-dev php8.3-xml
pecl install apcu

This yields:

WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
downloading apcu-5.1.22.tgz ...
Starting to download apcu-5.1.22.tgz (93,926 bytes)

Make sure that the file exists and is executable and then rerun this script.

ERROR: `phpize' failed

It works fine with php8.2 though.

Your understanding of what is happening

phpize8.3 does this:

+ cd /usr/lib/php/20230831/build
+ cp php.m4 shtool ax_check_compile_flag.m4 ax_gcc_func_attribute.m4 php_cxx_compile_stdcxx.m4 config.guess config.sub ltmain.sh Makefile.global gen_stub.php /tmp/pear/temp/apcu/build

However, shtool, config.guess, config.sub, and ltmain.sh are missing from /usr/lib/php/20230831/build.

I compared this with phpize8.2 and found this:

+ cd /usr/lib/php/20220829/build
+ cp php.m4 /usr/bin/shtool ax_check_compile_flag.m4 ax_gcc_func_attribute.m4 php_cxx_compile_stdcxx.m4 Makefile.global gen_stub.php /tmp/pear/temp/apcu/build
+ cd /usr/share/aclocal
+ cp pkg.m4 libtool.m4 ltoptions.m4 ltsugar.m4 ltversion.m4 lt~obsolete.m4 /tmp/pear/temp/apcu/build
+ cd /usr/share/libtool/build-aux
+ cp config.sub config.guess ltmain.sh /tmp/pear/temp/apcu/build
+ cd /usr/lib/php/20220829/build
+ cp run-tests.php /tmp/pear/temp/apcu/build

That is, config.guess, config.sub, and ltmain.sh are copied from /usr/share/libtool/build-aux, and shtool is copied from /usr/bin, not from /usr/lib/php/20230831/build

My further analysis showed that the php8.2 source has this patch that is missing in php8.3: 0036-In-phpize-also-copy-config.guess-config.sub-ltmain.s.patch. That patch fixes paths of the files in question.

What steps did you take to resolve issue yourself before reporting it here

Analyzed the sources of phpize8.2 and phpize8.3 and checked for patches that alter the original phpize.

To fix the issue for my Docker build, I had to use a workaround:

RUN cp \
    /usr/share/libtool/build-aux/config.sub \
    /usr/share/libtool/build-aux/config.guess \
    /usr/share/libtool/build-aux/ltmain.sh \
    /usr/bin/shtool \
    /usr/lib/php/20230831/build
