Bug #81639 [Asn->Wfx]: GD does not allow to import exported symbols on Windows

Edit report at https://bugs.php.net/bug.php?id=81639&edit=1 ID: 81639 Updated by: cmb@php.net Reported by: cmb@php.net Summary: GD does not allow to import exported symbols on Windows -Status: Assigned +Status: Wont fix Type: Bug Package: GD related Operating System: Windows PHP Version: 7.4Git-2021-11-19 (Git) Assigned To: cmb Block user comment: N Private report: N New Comment: Argh! That has already been done for PHP-8.0[1], and given the unfortunate naming of php_gd2.dll we can't use ADD_EXTENSION_DEP() anyway for PHP 7, so I'm closing this as WONTFIX.

This is particularly surprising, since there is even a respective comment in the GD sources, claiming that phpi_get_le_gd() is needed for cpdf[2].
