Description:
------------
If pdo_sqlite is compiled as shared with bundled sqlite, the module fails to load with following error:
: symbol lookup error: /usr/local/php73/lib/php/extensions/no-debug-non-zts-20180731/pdo_sqlite.so: undefined symbol: sqlite3_libversion


./configure --with-sqlite3=shared --with-pdo-sqlite=shared
make && make install

add to php.ini
extension=sqlite3.so
extension=pdo_sqlite.so

php -i|grep sqlite -A 5

phpPDO drivers => sqlite
: symbol lookup error
: /usr/local/php73/lib/php/extensions/no-debug-non-zts-20180731/pdo_sqlite.so: pdo_sqlite
undefined symbol: sqlite3_libversion

PDO Driver for SQLite 3.x => enabled



The solution suggested by jd at cpanel in bug 48614 works - patching configure script with this:
   else
       # use bundled libs
+
+      # This change is anchored here to avoid patch being misapplied.  This really only needs to be added
+      # when pdo_sqlite is compiled shared and using the bundled sqlite3.  It shouldn't hurt so long as the
+      # bundled sqlite3 is used though.
+      shared_objects_pdo_sqlite="$shared_objects_pdo_sqlite ext/sqlite3/libsqlite/sqlite3.lo"
+
       if test "$enable_maintainer_zts" = "yes"; then
         threadsafe_flags="-DSQLITE_THREADSAFE=1"
       else

However all of these are workarounds and they are not perfect. I want to use bundled sqlite, because php is tested with it and I don't want to patch configure script every time because updating gets more complicated.

I didn't write in bug 48614 because I assume it's for (unsupported) php 5 and that's why it's not fixed. I'm not sure if php 7 bugs have to be repored separately.

Test script:
---------------
<?php
// make sure to load pdo_sqlite.so extension in php.ini

$memory_db = new PDO("sqlite::memory:");




Expected result:
----------------
no error message

Actual result:
--------------
php: symbol lookup error: /usr/local/php73/lib/php/extensions/no-debug-non-zts-20180731/pdo_sqlite.so: undefined symbol: sqlite3_open_v2
