8.3.0 build fails on centos 8 with mbstring related error

[Xerkus]

Description

PHP 8.3.0 build fails on centos 8 with the error:

/usr/bin/ld: dynamic STT_GNU_IFUNC symbol `mb_utf16be_to_wchar' with pointer equality in `ext/mbstring/libmbfl/filters/mbfilter_utf16.o' can not be used when making an executable; recompile with -fPIE and relink with -pie
collect2: error: ld returned 1 exit status

Original failure discovered during 8.3.0 build at
php-build/php-build#759

Recreated locally in centos:8 docker image running configure and make directly. Full build log output available here https://gist.github.com/Xerkus/185b0a566abe8acee620b9a0ae84468d

Used configure as follows, no env variables used:

This issue looks similar to me #11603

PHP Version

8.3.0

Operating System

Centos 8

This is actually this issue: https://sourceware.org/bugzilla/show_bug.cgi?id=23169
That was fixed in binutils 2.31, but CentOS8 uses version 2.30 which is old (almost 6 years: Jan 2018).
I don't know how to work around this, it's not like we can check via a macro the binutils version but we could in principle test during configure if this is broken (although I prefer not to)...
In any case I really recommend you to use a modern toolchain.

[Girgias]

I am going to close this as this is not a bug in PHP.

[wheakerd]

Remove binutils from Centos 8 stream and remove them from https://ftp.gnu.org/gnu/binutils/ Compile and install the latest source code from Zhongla. This will solve this problem.

[remicollet]

Notice: I'm used to build all PHP versions (up to 8.3) on EL-7, EL-8 and EL-9, and never encounter this issue.

If you need recent versions, simply use https://rpms.remirepo.net/wizard/

So all users of Centos8 / Almalinux 8 / Rockylinux 8 should just resign to not using PHP 8.3 and newer because of a compiler bug that you are very well capable of bypassing so far much easier than an entire family of users removing an integral part of the original OS with a plethora of unexpected consequences ?

[nielsdos]

Why should I spend my free time in the weekend providing a workaround for an oerating system that the company is dropping support for, and shipping the operating system with a known compiler bug? Makes no sense to me.

In any case, feel free to provide a PR.

Or, hear me out, they discover here default binutils is too old in their EOL os, so they install and enable newer devtoolset with recent binutils and happily build php 8.3 using that.

In Almalinux 8 it is possible to add newer gcc for example by
dnf install gcc-toolset-13
and build PHP 8.3 with mbstring against it.

Thank you jirikmik, you saved me a lot of headaches.

To follow up with that, so you don't have to look it up - after installing the toolset you can use this command to run make:

scl enable gcc-toolset-13 make

[nstiac]

I wouldn't recommend installing a newer gcc just like that. I did and it turned up braking other things that were dynamically linked to the older library but were being given the new one even when installed purposefully with this in mind and even when reinstalled/recompiled with the newer gcc .. it became hell. But hey.. maybe it was just me and some setting I mishandled or the fact that not all of the software is on the latests available versions (because we need it to be like that due to some old code still working on older versions and because Centos itself does not work well with the latest versions) Yahoo Mail: Search, Organize, Conquer On Thu, Mar 28, 2024 at 3:11 PM, Steven ***@***.***> wrote: In Almalinux 8 it is possible to add newer gcc for example by dnf install gcc-toolset-13 and build PHP 8.3 with mbstring against it.

Using the toolset doesn't replace the GCC already installed, it sets up its own environment. While I am still testing things, the compile went through without problems (PHP 8.3.4 on AlmaLinux 8.9) and I am not getting any issues so far after compiling without specifying the GCC directly from the compiled php binary.
