I am in windows 7. I installed WAMPServer. Now, I can not load spatialite libraries. It is showing warning..

Warning: SQLite3::loadExtension() [sqlite3.loadextension]: Not supported in multithreaded Web servers

Here is my total configuration procedure, what I have done...

From this link I got spatialite lib. I copied "libspatialite-1.dll" and paste it to "D:\wamp\bin\php\php5.3.8\ext" which contains php extention dlls.


Then I edited php.ini file. I changed the following configuration.

sqlite3.extension_dir = C:\libspatialite-win-x86-2.3.1\bin
enable_dl = On

And lastly, I copy and paste all the libraries from my downloaded libspatialite-win-x86-2.3.1 to my project folder(libspatialite.a, libspatialite.dll.a, libspatialite.la) in my php code i write the script as follows...


$db = new SQLite3('sixcommunes.sqlite'); 


$rs = $db->query('SELECT spatialite_version()');
while($row = $rs->fetchArray()){
    print "<h3>SQLite version: $row[0]</h3>";


I do not know what I have done wrong or how to solve this problem?

  • This is more of an Apache issue than a GIS issue. Have you tried stackoverflow? You might get more luck there.

Did you ever get this resolved? If not, try replacing the .a suffix with .dll. You can't load an archive (.a) in place of a shared library (.dll).
