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

From: p.pastori@acsys.it Operating system: IRIX 6.5 (6.5.8m) PHP version: 4.0.3pl1 PHP Bug Type: *Install and Config Bug description: configure fails to found system headers during `Running system checks' phase Rightly you simply use the prepocessor during the check phase, instead of try to compile. 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. -- Edit Bug report at: http://bugs.php.net/?id=7725&edit=1
