Bug #74288 [NEW]: php check for isinf is wrong

From: apyhalov at gmail dot com Operating system: illumos PHP version: 7.0.17 Package: Compile Failure Bug Type: Bug Bug description:php check for isinf is wrong Description: ------------ In latest php versions it checks for isinf with AC_CHECK_DECLS([isnan, isinf], [], [], [[#include <math.h>]]), which leads to defining #define HAVE_DECL_ISINF 0 when isinf is not declared. Later it checks for it with #ifdef HAVE_DECL_ISINF #define zend_isinf(a) isinf(a) #elif defined(INFINITY) /* Might not work, but is required by ISO C99 */ #define zend_isinf(a) (((a)==INFINITY || (a)==-INFINITY)?1:0) #elif defined(HAVE_FPCLASS) #define zend_isinf(a) ((fpclass(a) == FP_PINF) || (fpclass(a) == FP_NINF)) #else #define zend_isinf(a) 0 #endif This should be changed to something like #if defined(HAVE_DECL_ISINF) && (HAVE_DECL_ISINF!=0) ... This is also true for HAVE_DECL_ISNAN and HAVE_DECL_ISFINITE Otherwise linking php fails with 'Undefined symbol isinf...'. -- Edit bug report at https://bugs.php.net/bug.php?id=74288&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74288&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74288&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74288&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74288&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74288&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74288&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74288&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74288&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74288&r=support Expected behavior: https://bugs.php.net/fix.php?id=74288&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74288&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74288&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74288&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74288&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74288&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74288&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74288&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74288&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74288&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74288&r=mysqlcfg
