[Pw_forum] Regarding the installation problem in running configure.

[Tushar Gupta]

Thank you so much surender but as I runned the locate fftw.f command it
showed the following response. it is not able to find the concerned
directory.

[vipin at localhost espresso-5.3.0]$ locate fftw3.f
warning: locate: could not open database: /var/lib/slocate/slocate.db: No
such file or directory
warning: You need to run the 'updatedb' command (as root) to create the
database.
Please have a look at /etc/updatedb.conf to enable the daily cron job.

Regards:
Tushar
