Edit report at https://bugs.php.net/bug.php?id=69928&edit=1 ID: 69928 Updated by: laruence@php.net Reported by: 191919 at gmail dot com Summary: -ffast-math incompatible with sqlite extension -Status: Open +Status: Feedback Type: Feature/Change Request Package: Compile Failure Operating System: OS X PHP Version: 7.0Git-2015-06-25 (Git) Block user comment: N Private report: N New Comment: from what I read in http://sqlite.1065341.n5.nabble.com/GCC-ffast-math-safe-version-of-sqlite3IsNaN-td41243.html , no we can not do much thing on this. but you may try to build php without sqlite and enable fast-math. then build sqlite as a shared object without fast-math.. thanks Previous Comments: ------------------------------------------------------------------------ [2015-06-25 08:14:36] 191919 at gmail dot com Description: ------------ -ffast-math brings performance increase and the precision can be accepted in most cases, but php cannot be compiled with this directive. Would you please consider to add an extra ./configure setting to skip the check in sqlite3 extension as it is the only one that explicitly refuses the -ffast-math flag? Test script: --------------- CC=/opt/bin/gcc CFLAGS="-O2 -msse4.2 -ffast-math -fomit-frame-pointer -fno-stack-protector -fno-exceptions" ./configure --prefix=/opt/php7 --enable-opcache Expected result: ---------------- Compilation succeeds. Actual result: -------------- gcc-5.1.0 gave: /Users/xx/box/php-src/ext/sqlite3/libsqlite/sqlite3.c:23512:3: error: #error SQLite will not work correctly with the -ffast-math option of GCC. # error SQLite will not work correctly with the -ffast-math option of GCC. ^ ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69928&edit=1
