Previous Comments: ------------------------------------------------------------------------ [2017-05-03 05:23:12] rasmus@php.net gcc version 4.1.2 ?? That compiler is over 10 years old. You are probably going to need to add -std=c99 to your build flags to get it to work on any modern codebase, or for heaven's sake, upgrade to a compiler from this decade. ------------------------------------------------------------------------ [2017-05-03 02:09:03] letshi at 163 dot com Still having problems building 7.1.4 on CentOS5.5 gcc version 4.1.2 20080704 (Red Hat 4.1.2-55) ldd (GNU libc) 2.5 ext/standard/.libs/var.o: In function `php_var_export_ex': /PHP/32/source/php7.1.4_zts/ext/standard/var.c:473: undefined reference to `isfinite' main/.libs/php_variables.o: In function `zend_dval_to_lval': /PHP/32/source/php7.1.4_zts/Zend/zend_operators.h:117: undefined reference to `isfinite' Zend/.libs/zend_operators.o: In function `zendi_smart_strcmp': /PHP/32/source/php7.1.4_zts/Zend/zend_operators.c:2789: undefined reference to `isfinite' Zend/.libs/zend_operators.o: In function `zend_dval_to_lval': /PHP/32/source/php7.1.4_zts/Zend/zend_operators.h:117: undefined reference to `isfinite' /PHP/32/source/php7.1.4_zts/Zend/zend_operators.h:117: undefined reference to `isfinite' Zend/.libs/zend_operators.o:/PHP/32/source/php7.1.4_zts/Zend/zend_operators.h:117: more undefined references to `isfinite' follow collect2: ld returned 1 exit status make: *** [sapi/cli/php] Error 1 ------------------------------------------------------------------------ [2017-05-02 02:46:42] yzaptx at gmail dot com Sorry for the previous, incomplete comment.
