Question

I am trying to install Tk-ExecuteCommand package which i downloaded from CPAN.

While installing i am getting this error.

sait109@debian:~/Desktop/Tk-ExecuteCommand-1.6$ sudo make
make: Warning: File `/usr/lib/perl/5.10/Config.pm' has modification time 2.3e+07 s in the future

Does anyone knows a fix for this. Help pls..

Answer 1

The important part of that message is

make: Warning: File `/usr/lib/perl/5.10/Config.pm' has modification time 2.3e+07 s in the future
Makefile out-of-date with respect to /usr/lib/perl/5.10/Config.pm /usr/lib/perl/5.10/CORE/config.h /usr/local/lib/perl/5.10.0/Tk/Config.pm

Your local timestamps are screwed up, causing make to be confused as various targets in the Makefile depend on the /usr/lib/perl/5.10/Config.pm from the future.

Fix the timestamps on your system or your system clock, depending on which is wrong, and things will be fine.

Additionally, you’re seeing warnings for having a locale en configured, but not installed. I’m not aware of any locale by that name existing. You might’ve meant something like en_US.UTF-8, which you’ll also have to install, once configured. However, this is unrelated to the error you’re getting.
