Troubles with while(!feof($socket_id)) and compiling php-4.0.6 ... help please :(

Hello, i was using php-4.0.3pl1 until now and never had any problem, except yesterday i had to develop a page on which i have to read on a socket .... problem is that: while(!feof($socket_id)) { echo fgets($socket_id, $len); } does not work: seems that FEOF is never detected so the PHP enter an infinite loop. I found many people complaining about that problem on different PHP mailing-list, but no real issue ... So i decided to upgrade PHP, and also apache, and also mysql. downlaoded php-4.0.6 sources (ieve always used sources) and when i compile it: gcc -I. -I/root/php-4.0.6/ext/standard -I/root/php-4.0.6/main -I/root/php-4.0.6 -I/root/apache_1.3.20/src/include -I/root/apache_1.3.20/src/os/unix -I/root/php-4.0.6/Zend -I/usr/local/mysql/include/mysql -I/root/php-4.0.6/ext/xml/expat/xmltok -I/root/php-4.0.6/ext/xml/expat/xmlparse -I/root/php-4.0.6/TSRM -DSUPPORT_UTF8 -DXML_BYTE_ORDER=12 -g -O2 -c microtime.c && touch microtime.lo microtime.c: In function `php_if_getrusage': microtime.c:99: storage size of `usg' isn't known microtime.c:102: `RUSAGE_SELF' undeclared (first use in this function) microtime.c:102: (Each undeclared identifier is reported only once microtime.c:102: for each function it appears in.) microtime.c:108: `RUSAGE_CHILDREN' undeclared (first use in this function) make[3]: *** [microtime.lo] Error 1 make[3]: Leaving directory `/root/php-4.0.6/ext/standard' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/root/php-4.0.6/ext/standard' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/php-4.0.6/ext' make: *** [all-recursive] Error 1 mushroom:~/php-4.0.6# any help would be really appreciated ... :) thanks Arnauld Dravet smurfie@artefact21.net
