Error compiling Apache 1.3.24 with PHP 4.1.2

Hello, I am trying to compile Apache 1.3.24 with PHP 4.1.2, but when compiling I get the following errors: modules/php4/libphp4.a(dns.o): In function `zif_checkdnsrr': /home/admin/php-4.1.2/ext/standard/dns.c:223: undefined reference to `__res_search' modules/php4/libphp4.a(dns.o): In function `zif_getmxrr': /home/admin/php-4.1.2/ext/standard/dns.c:284: undefined reference to `__res_search' /home/admin/php-4.1.2/ext/standard/dns.c:311: undefined reference to `__dn_expand' collect2: ld returned 1 exit status make[2]: *** [target_static] Error 1 make[2]: Leaving directory `/home/admin/apache_1.3.24/src' make[1]: *** [build-std] Error 2 make[1]: Leaving directory `/home/admin/apache_1.3.24' make: *** [build] Error 2 In the PHP bug tracking system and found #13565. In reply to this bug ticket, it was said that it was probably a problem with /lib/libresolv.so.2. I reinstalled glibc-2.1.3-23 (Redhat RPM), which includes this libresolv.so.2, but it did not help. I am running Redhat 6.2 on my system. Any suggestions and/or help would be really appreciated. Thanks in advance, Jasper
