Hi i am using a script to build php4.3.1 on an old server that i cannot u/g to a later apache/OS. script is below #!/bin/sh ./configure \ "--with-apache=../apache_1.3.12" \ "--with-openssl-dir=../openssl-0.9.5a" \ "--enable-sockets" \ "--with-zlib" \ "--with-db2" \ "--with-ttf" \ "--enable-gd-native-ttf" \ "--with-gdbm" \ "--with-gettext" \ "--with-regex=system" \ "--enable-ftp" \ "--with-gd" \ "--with-jpeg-dir=/usr" \ "--with-png" \ "--enable-sysvsem" \ "--enable-sysvshm" \ "--enable-magic-quotes" \ "--enable-trans-sid" \ "--with-pgsql" \ "$@" runs ok but make exits with (i only include the last few lines) libtool: link: warning: library `/usr/lib/libgdbm.la' was moved. libtool: link: warning: library `/usr/lib/libgdbm.la' was moved. ext/pgsql/pgsql.o: In function `php_pgsql_flush_query': /home/src/php-4.3.1/ext/pgsql/pgsql.c:2838: undefined reference to `PQsetnonblocking' /home/src/php-4.3.1/ext/pgsql/pgsql.c:2846: undefined reference to `PQsetnonblocking' collect2: ld returned 1 exit status make: *** [sapi/cli/php] Error 1 [root@proteus php-4.3.1]# now from google i see the warnings can be ignored but i am unsure about the Error 1 this is my first post to this group and i hope it is the correct group.
