Building Calibre

Hi
I'm trying to build but getting this error:
./setup.py install

libstemmer.h is installed and can be found in /usr/include/libstemmer

Does anyone have idea what is wrong?

calibre assumes libstemmer.h is in the default include path aka /usr/include

I copied it to /usr/include and it compiled ok.
Thanks.

Compilation worked fine until 5.23 version. Then I'm getting error below.
File "/usr/lib/calibre/calibre/db/backend.py", line 1214, in user_version
return self.conn.get('pragma user_version;', all=False)
File "/usr/lib/calibre/calibre/db/backend.py", line 927, in conn
self._conn = Connection(self.dbpath)
File "/usr/lib/calibre/calibre/db/backend.py", line 342, in __init__
plugins.load_apsw_extension(self, 'sqlite_extension')
File "/usr/lib/calibre/calibre/constants.py", line 325, in load_apsw_extension
conn.enableloadextension(True)
AttributeError: 'Connection' object has no attribute 'enableloadextension'


I build and install apsw version from sources.json but still same error.
What I'm missing?

Compiled apsw with --enable-all-extensions and it works fine now.
Thanks.
