Confusion on how to exclude embedded sqlite3 during make/build

Hi. I am trying to compile php against httpd 2.4.2 - but before it gets interesting I think I am having a different problem. The sqlite3 embedded in ./ext/sqlite3 returns a syntax error against vac.C v11 compiler. data/prj/php-5.3.13/ext/sqlite3/sqlite3.c -o ext/sqlite3/sqlite3.lo "/data/prj/php-5.3.13/ext/sqlite3/sqlite3.c", line 893.9: 1506-046 (S) Syntax error. "/data/prj/php-5.3.13/ext/sqlite3/sqlite3.c", line 894.41: 1506-045 (S) Undeclared identifier i. "/data/prj/php-5.3.13/ext/sqlite3/sqlite3.c", line 894.51: 1506-277 (S) Syntax error: possible missing ';' or ','? "/data/prj/php-5.3.13/ext/sqlite3/sqlite3.c", line 894.65: 1506-045 (S) Undeclared identifier or. make: 1254-004 The error code from the last command is 1. Rather than try and solve that I compiled a separate sqlite3 version root@x104:[/]sqlite3 -version 3.6.22 However, even after make distclean and a new run of configure with the following arguments - make still continues to try to compile the embedded sqlite3. root@x104:[/data/prj/php-5.3.13]cat php_configure.ksh #!/usr/bin/ksh set -x ./configure \ --prefix=/opt \ --sysconfdir=/etc \ --mandir=/usr/share/man \ --with-libdir=/opt/lib \ --with-sqlite3=/opt \ > build/aix/configure.out What am I doing wrong? Many thanks! Michael
