Installing PHP4.02 with Apache 1.3.12

When installing PHP4.02 as a static object in Apache 1.3.12, I get the following errors : <=== src/modules/standard ===> src/modules/php4 gcc -c -I../../os/unix -I../../include -DLINUX=2 -DUSE_HSREGEX -DUSE_EXPAT -I../../lib/expat-lite -DNO_DL_N EEDED ../../apaci mod_php4.c In file included from zend.h:43, from mod_php4.c:28: zend_config.h:1: ../php_config.h: No such file or directory mod_php4.c:29: php.h: No such file or directory mod_php4.c:30: php_variables.h: No such file or directory mod_php4.c:31: SAPI.h: No such file or directory mod_php4.c:48: php_ini.h: No such file or directory mod_php4.c:49: php_globals.h: No such file or directory mod_php4.c:50: SAPI.h: No such file or directory mod_php4.c:51: php_main.h: No such file or directory mod_php4.c:58: ext/standard/php_standard.h: No such file or directory make[4]: *** [mod_php4.o] Error 1 make[3]: *** [all] Error 1 make[2]: *** [subdirs] Error 1 make[2]: Leaving directory `/install/apache_1.3.12/src' make[1]: *** [build-std] Error 2 make[1]: Leaving directory `/install/apache_1.3.12' make: *** [build] Error 2 It seems to be installing all of the header files in : /usr/local/include/php and Apache doesn't know how to include them from there : it's looking locally. How do I get around this, make PHP 4.02 install the include files correctly, or point Apache at the include directory? Regards, Vin
