Bug #78348 [Opn]: Remove -lrt from pdo_sqlite.so because fdatasync removed in 5.3

Edit report at https://bugs.php.net/bug.php?id=78348&edit=1 ID: 78348 User updated by: rainer dot jung at kippdata dot de Reported by: rainer dot jung at kippdata dot de Summary: Remove -lrt from pdo_sqlite.so because fdatasync removed in 5.3 Status: Open Type: Bug Package: PDO SQLite Operating System: Solaris PHP Version: 7.4.0beta1 Block user comment: N Private report: N New Comment: You are right! So dropping for 7.4 is save and you can keep it as is in 7.2/7.3. It is just a minor cleanup. Having the rt lib as an unneeded dependency is not critical, but removing complexity is always nice (for 7.4). Previous Comments: ------------------------------------------------------------------------ [2019-07-29 13:13:29] cmb@php.net While ext/pdo_sqlite/sqlite/* is removed as of PHP 5.3.0, pdo_sqlite defaults to using ext/sqlite3/libsqlite/* (the latter is only removed as of PHP 7.4.0), where -lrt *might* still be needed. ------------------------------------------------------------------------ [2019-07-29 12:07:19] rainer dot jung at kippdata dot de Description: ------------ PDO SQLite still contains the following configure test in its config.m4: dnl Solaris fix PHP_CHECK_LIBRARY(rt, fdatasync, [PHP_ADD_LIBRARY(rt,, PDO_SQLITE_SHARED_LIBADD)]) This check can be dropped, because the fdatasync was only used inside the bundled sqlite, but starting with 5.3 sqlite is no longer bundled but expected as an external dependency. So libsqlite3.so itself would have that dependency, but the pdo-sqlite.so extension should not have an entry for -lrt any more. You can simply drop the two lines from ext/pdo_sqlite/config.m4 (and regenerate configure). This applies to any PHP version starting with 5.3 and up until 7.4beta1. Note that older bugs are about fdatasync being used but -lrt missing. This is about fdatasync no longer being used but -lrt still present. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78348&edit=1
