Bug #68114 [Com]: Build fails with gcc: Undefined symbols: ___extendsddf ___extendsfsd

Edit report at https://bugs.php.net/bug.php?id=68114&edit=1 ID: 68114 Comment by: swa at section66 dot com Reported by: php-bugs-2014 at ryandesign dot com Summary: Build fails with gcc: Undefined symbols: ___extendsddf ___extendsfsd Status: Assigned Type: Bug Package: MySQL related Operating System: OS X PHP Version: 5.5.17 Assigned To: keyur Block user comment: N Private report: N New Comment: It's not just OS X ! At least OpenBSD and FreeBSD all have the same (or highly similar) problem in 5.5.20 and 5.6.4 The workaround of adding "ac_cv_decimal_fp_supported=no" to the configure options seems to get through the compile phase on 5.6.4 on OpenBSD already. The snippet on OpenBSD: $ gcc -o t t.c /tmp//ccaYXIKe.o(.text+0x29): In function `main': : undefined reference to `__extendsddf' collect2: ld returned 1 exit status $ gcc -O2 -o t t.c $ ./t Expected: 99.49, Actual: 99.490000 Suggest to either make sure the optimizer doesn't optimize the test program or remove the optimizer in options during the configure as it's too smart to execute the test. [I'm not that familiar with the PHP build system] FWIW: it's an old OpenBSD version I'm running - I know ... gcc version 4.2.1 20070719 Previous Comments: ------------------------------------------------------------------------ [2014-12-23 21:14:38] php at wesha dot name (Re: https://bugs.php.net/bug.php?id=68192#1412808117) https://bugs.php.net/bug.php?id=68114#1412845446 solution worked for me. ------------------------------------------------------------------------ [2014-12-11 18:34:13] php-bugs-2014 at ryandesign dot com @cbrugh, a workaround you can use immediately is described in my comment above from 2014-10-09 09:04 UTC.
