Bug #77883 [NEW]: Building with gcc-3.4.3 fails to export symbols

From: a dot hawkins at cabletime dot com Operating system: Linux PHP version: 7.3.4 Package: *Compile Issues Bug Type: Bug Bug description:Building with gcc-3.4.3 fails to export symbols Description: ------------ When building with the following version of gcc: andyh@778:/home/andyh/development/778-phpv7$ arm_v5t_le-gcc --version arm_v5t_le-gcc (GCC) 3.4.3 (MontaVista 3.4.3-25.0.104.0600975 2006-07-06) Copyright (C) 2004 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. configure.ac checks if the -fvisibility=hidden flag is acceptable to the compiler. If it is, it uses it. However, this compiler supports this flag, but doesn't support the attribute required to be able to export symbols (this requires gcc v4 or above). The result is that php builds, but it is not possible to load any modules, as php's symbols aren't correctly exported. This flag should only be used if the compiler *also* supports the 'visibility' function attribute. -- Edit bug report at https://bugs.php.net/bug.php?id=77883&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77883&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77883&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77883&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77883&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77883&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77883&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77883&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77883&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77883&r=support Expected behavior: https://bugs.php.net/fix.php?id=77883&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77883&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77883&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77883&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77883&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77883&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77883&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77883&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77883&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77883&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77883&r=mysqlcfg
