#18617 [Com]: warning: empty declaration

ID: 18617 Comment by: phpbugs@drcheap.com Reported By: phpbugs@drcheap.com Status: Feedback Bug Type: Compile Failure Operating System: Slackware Linux 8.0 (2.4.5 krnl) PHP Version: 4.2.2 New Comment: Here those items +/- a few lines to put them in context: /usr/include/stdlib.h -------- 143:#if defined __USE_ISOC99 || (defined __GNUC__ && defined __USE_MISC) 144:/* Convert a string to a long long integer. */ 145:__extension__ extern long long int atoll (__const char *__nptr) 146: __THROW __attribute_pure__; 147:#endif -------- main/php_config.h -------- 2046:#ifdef HAVE_ISNAN 2047:#define zend_isnan(a) isnan(a) 2048:#elif defined(NAN) 2049:#define zend_isnan(a) (((a)==NAN)?1:0) 2050:#elif defined(HAVE_FPCLASS) 2051:#define zend_isnan(a) ((fpclass(a) == FP_SNAN) || (fpclass(a) == FP_QNAN)) 2052:#else 2053:#define zend_isnan(a) 0 2054:#endif -------- Previous Comments: ------------------------------------------------------------------------ [2002-07-28 21:17:43] msopacua@idg.nl what's at /usr/include/stdlib.h on line 144/146 An empty declaration is something like: #define int socklen_t Other file: typedef int socklen_t; Result: typedef int int; They are harmless though in most cases, but this is one I bumped to recently also. Could you also list line 2048 of main/php_config.h? ------------------------------------------------------------------------ [2002-07-28 21:05:05] phpbugs@drcheap.com Yes, defintely. I even went over to my old PHP 4.1.2 source tree and ran a make clean then make and it went smooth. ------------------------------------------------------------------------ [2002-07-28 21:03:24] rasmus@php.net Well, do other things compile on that server? ------------------------------------------------------------------------ [2002-07-28 21:01:27] phpbugs@drcheap.com I am unable to successfully compile PHP... No matter what combination of configure options I use (even just running configure by itself) I always get output such as this during the make process: ------------ /bin/sh ../libtool --silent --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../main -I../TSRM -g -O2 -prefer-non-pic -static -c -o zend_language_parser.lo `test -f zend_language_parser.c || echo './'`zend_language_parser.c In file included from /usr/include/stdlib.h:391, from ../main/php_config.h:2084, from zend_config.h:1, from zend.h:48, from zend_compile.h:24, from zend_language_parser.c:147: /usr/include/sys/types.h:144: warning: empty declaration /usr/include/sys/types.h:146: warning: empty declaration ------------ This same warning is reported for pretty much EVERY SINGLE item that is built during make. When the process completes, I have no errors reported, just TONS of warnings like above. Additionally, the libs/libphp4.so file (and maybe others) are not created, which causes make install to fail. I find no previous mention of this problem anywhere (web, usenet, etc.), perhaps you can make sense of it. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18617&edit=1
