[egenix-users] Changing extension paths in mxCOMMERCIAL.py?

[Chuck Bearden]

I want to create an alternate installation of mx.ODBC to test a new
combination of iODBC and FreeTDS.  I therefore need to have the
mx.ODBC build process ignore the iODBC and FreeTDS installations in
/usr/local.  I have edited mxCOMMERCIAL.py to point to the test
installations:

Extension('mx.ODBC.iODBC.mxODBC',
          ['mx/ODBC/iODBC/mxODBC.c',
           'mx/ODBC/iODBC/mxSQLCodes.c'
           ],
          include_dirs=['mx/ODBC/iODBC',
                        '/home/cbearden/opt/libiodbc-3.52.1/include'],
          define_macros=[('iODBC', None)],
          library_dirs=['/home/cbearden/opt/libiodbc-3.52.1/lib'],
          libraries=['iodbc']
          ),

After I run 'python setup.py install --home=/home/cbearden/opt1', the
mxODBC.so still seems to depend on the installations in /usr/local :

$ ldd opt1/lib/python/mx/ODBC/iODBC/mxODBC.so
        libiodbc.so.2 => /usr/local/libiodbc/lib/libiodbc.so.2 (0x4002d000)
        libpthread.so.0 => /lib/tls/libpthread.so.0 (0x40069000)
        libc.so.6 => /lib/tls/libc.so.6 (0x42000000)
        libiodbcinst.so.2 =>
/usr/local/libiodbc-3.51.2/lib/libiodbcinst.so.2 (0x40077000)
        libdl.so.2 => /lib/libdl.so.2 (0x40081000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

I get the same result when I run ldd against the mxODBC.so in the source tree.

Is there some precaution I need to take when building mx.ODBC to force
it to use a particular set of libraries and includes in a non-standard
location?

Thanks,
