PHP 4.0 Bug #7725 Updated: configure fails to found system headers during `Running system checks' phase

ID: 7725 User Update by: p.pastori@acsys.it Old-Status: Feedback Status: Open Bug Type: *Install and Config Description: configure fails to found system headers during `Running system checks' phase I tried the last version available (that is php4-200011220845) as asked by Jani. Sorry the bug is present as i stated the first time, following there are the config.log lines which may explain better the problem: configure:5704: checking for sys/socket.h configure:5714: /lib/cpp conftest.c >/dev/null 2>conftest.out cpp: warning /usr/include/sys/socket.h:169: AF_LINK redefined configure: failed program was: #line 5709 "configure" #include "confdefs.h" #include <sys/socket.h> A simple warning let you assume i miss the header...

Standard autoconf macros AC_CHECK_HEADER and AC_CHECK_HEADERS would probably invoke the compiler. Anyway be carefull to properly parse the prepocessor output before take any assumption, on my OS the preprocessor simply prints `warning' lines which let you assume that i miss the header under check. I had to manually change the configure script at line 5499 to solve the problem but you may do something better (i suppose). Following there is the modified configure's line: ac_err=grep -v '^ *+' conftest.out | grep -v 'warning' | grep -v "^conftest.${ac_ext}$" as you note i simply add a pipe into a `grep -v 'warning'' and now it's ok. --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=7725
