PHP7's 64bit support in Zend/zend_long.h uses INT64_MIN/MAX as well as INT64_C/INT32_C concat macros. In C++, these are only defined if __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS has been set prior to including stdint.h
A C++ extension developer could deal with this by defining those prior to including php.h, but I wonder if we should accommodate by either: A) Adding those defines prior to including stdint.h B) Expecting C++ ext devs to define those before including php.h C) Modifying zend_long.h to use things like std::numeric_limits<int64_t>() when __cplusplus is defined A may (potentially) have unexpected side-effects B has precedent (see ext/intl/config.m4) C makes the ifdef block that's already there notably more complex -Sara -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
