5. Configure and apply PHP4 to Apache source

Now, move into the new php4 directory cd ../php-4.0 and type the following commands on your terminal:

  1. Edit the php_pgsql.h file, vi ext/pgsql/php_pgsql.h and change the lines:

              #include libpq-fe.h
              #include libpq/libpq-fs.h

    To read:

              #include /usr/include/pgsql/libpq-fe.h
              #include /usr/include/pgsql/libpq/libpq-fs.h

    These modifications in the php_pgsql.h file are necessary to indicate the location of our libpq-fe.h, and libpq-fs.h header files of PostgreSQL database during configure of PHP4. In Red Hat Linux, the libraries of PostgreSQL are located under /usr/include/pgsql.

  2. Now, we must configure and install PHP4 in the Linux server:

              CC="egcs" \
              CFLAGS="-O9 -funroll-loops -ffast-math -malign-double -mcpu=pentiumpro -march=pentiumpro -fomit-frame-pointer -fno-exceptions -I/usr/include/openssl" \
              ./configure \
              --prefix=/usr \
              --with-exec-dir=/usr/bin \
              --with-apache=../apache_1.3.12 \
              --with-config-file-path=/etc/httpd \
              --disable-debug \
              --enable-safe-mode \
              --with-imap \                1
              --with-ldap \                2
              --with-pgsql \               3
              --with-mm \
              --enable-inline-optimization \
              --with-gnu-ld \


    If you want IMAP & POP support.


    If you want LDAP database light directory support.


    if you want PostgreSQL database support.

    This tells PHP4 to set itself up for this particular hardware setup with:

    • Compile without debugging symbols.

    • Enable safe mode by default.

    • Include IMAP & POP support.

    • Include LDAP directory support.

    • Include PostgresSQL database support.

    • Include mm support to improve performance of Memory Library.

    • Enable inline-optimization for better performance.

    • Compile with memory limit support.

    • Assume the C compiler uses GNU ld.
