Hello, I am attempting to install php4.04 and apache1.3.14 php configure commands: ./configure --with-apache=../apachessl-1.3.14 \ --with-jpeg-dir=/usr/local/lib --with-pgsql --with-gd \ --with-ttf=/usr/local/lib --with-t1lib=/usr/local/lib \ --enable-gd-imgstrttf --with-pfpro=/usr/local/lib apache configure commands: ./configure \ "--with-layout=Apache" \ "--target=https" \ "--prefix=/usr/local/apache-ssl" \ "--activate-module=src/modules/php4/libphp4.a" \ php4.04 compiles without complaint, yet when I compile apache, it dies on this error: ===== modules/php4/libphp4.a(pfpro.o): In function `php_info_pfpro': /usr/local/src/php-4.0.4-ssl/ext/pfpro/pfpro.c:113: undefined reference to `PNVersion' modules/php4/libphp4.a(pfpro.o): In function `php_if_pfpro_version': /usr/local/src/php-4.0.4-ssl/ext/pfpro/pfpro.c:129: undefined reference to `PNVersion' Anyone know what is going on here? I have copied pfpro.h to /usr/local/include and libpfpro.so /usr/local/lib and I ran ldconfig. Thanks Dan
