Bug #74904 [NEW]: zend_operators.h: Error: The function "isfinite" must have a prototype.

From: john dot woods at greatplainsmfg dot com Operating system: Solaris 11.3.21.5.0 (x86-64) PHP version: 7.1.7 Package: Compile Failure Bug Type: Bug Bug description:zend_operators.h: Error: The function "isfinite" must have a prototype. Description: ------------ We are compiling PHP 7.1.7 on Solaris 11.3.21.5.0 + idr3199, using Solaris Studio 12.5 compilers. During the build of the ./ext/intl extension, the following libtool command fails to build ext/intl/intl_convertcpp.lo: /bin/sh /tmp/SOURCE_DIR/libtool --silent --preserve-dup-deps --mode=compile CC -I/usr/include -Wno-write-strings -D__STDC_LIMIT_MACROS -DZEND_ENABLE_STATIC_TSRMLS_CACHE=1 -Iext/intl/ -I/tmp/SOURCE_DIR/ext/intl/ -DPHP_ATOM_INC -I/tmp/SOURCE_DIR/include -I/tmp/SOURCE_DIR/main -I/tmp/SOURCE_DIR -I/tmp/SOURCE_DIR/ext/date/lib -I/usr/include/libxml2 -I/usr/local/include -I/tmp/SOURCE_DIR/ext/sqlite3/libsqlite -I/tmp/SOURCE_DIR/TSRM -I/tmp/SOURCE_DIR/Zend -D_POSIX_PTHREAD_SEMANTICS -g -c /tmp/SOURCE_DIR/ext/intl/intl_convertcpp.cpp -o ext/intl/intl_convertcpp.lo "/tmp/SOURCE_DIR/Zend/zend_portability.h", line 251: Warning (Anachronism): Attempt to redefine __restrict__ without using #undef. "/tmp/SOURCE_DIR/Zend/zend_operators.h", line 117: Error: The function "isfinite" must have a prototype. "/tmp/SOURCE_DIR/Zend/zend_operators.h", line 128: Error: The function "isfinite" must have a prototype. 2 Error(s) and 1 Warning(s) detected. *** Error code 1 make: Fatal error: Command failed for target `ext/intl/intl_convertcpp.lo' Upon investigation, the "isfinite" comes from zend_finite(), which gets #define(d) as "isfinite" only if HAVE_DECL_ISFINITE is true (lines 93-101 of Zend/configure.in). The HAVE_DECL_ISFINITE is set by the main configure script, if "isfinite" is defined by #include(ing) <math.h>. I'm convinced that the root of this problem is that "isfinite" is a valid function with Solaris Studio's C compiler. But with the C++ compiler, "std::isfinite" is not defined, since the default C++ dialect is C++ 03. The file it is trying to build is ext/intl/intl_convertcpp.cpp. I tried adding "-std=sun03" or "-std=c++03" to CXXFLAGS, but still had the problem. I also tried setting the flags to "-std=c++11" and "-std=c++14", to force the C++ 11 or C++ 14 dialect, but those options prevented linking to the GCC/G++ libraries, which caused other compile problems. The only way I could get this to compile and work, was forcing HAVE_DECL_ISFINITE, HAVE_DECL_ISNAN, and HAVE_DECL_ISINF to be 0 in the main configure script, to avoid this altogether. I know it's a bad hack, but it did actually work around the issue. I don't believe this is a duplicate of Bug #74265, since this is a C++ issue.
