ERROR: not found /lib64/libc.so.6: version `GLIBC_2.14

[Josh Kamau]

When i compile a certain library, (https://bitbucket.org/liamstask/goose/)  it runs perfectly on my fedora20. When i send the binary to the server (centos 6.5), i get the below error when i run it. 

./goose:' not found /lib64/libc.so.6: version `GLIBC_2.14 (required by ./goose)

Does it mean that the library is not pure go and that it requires some c libraries that are not statically compiled with it?

If i do a simple hello world and send it to the same sever, it works perfectly.

By default, even programs that are pure Go do link aginst libc if they
do any DNS lookups or user name lookups. This is because those
operations are highly system-dependent to deal with things like
firewalls and LDAP.

You can force the use of a pure-Go DNS lookup by building with "-tags
netgo". Note that that means that your program will not honor the
/etc/nsswitch.conf file. Or you can build your program on your CentOS
machine.

Thanks Ian, 

are " DNS lookups or user name lookups" the only standard lib apis that link agains libc?

At present, yes. Specifically the net and os/user packages.
