Research direction

Start by reproducing asdf install php 8.3.11 on RHEL 8 and inspect the sapi/fpm/php-fpm target in Makefile along with ext/mbstring/libmbfl/filters/mbfilter_utf16.o. Check the reported PIE-related linker failure and the listed dependency and re2c requirements. Done means PHP 8.3.11 installs successfully through asdf on the reported environment.

Description

Provide environment information

When I try to install PHP, then I get a compilation error.

PHP 8.3.11
RHEL 8

To Reproduce
$ asdf install php 8.3.11
/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
make: *** [Makefile:323: sapi/fpm/php-fpm] Error 1
Describe the Bug

Some kind of PIE related compilation error occurs when installing PHP.

As an aside, several packages were needed but not documented in the PHP instructions:

  • Unclear which versions of re2c are supported
  • Python > 3.7 (for latest re2c)
  • libxml2-dev(el)
  • libcurl-dev(el)
  • gd-dev(el)
  • libicu-dev(el)
  • oniguruma-dev(el)
  • libpq-dev(el)
  • libzip-dev(el)
Expected Behaviour

asdf install php 8.3.11 should succeed.
