: is a rune that cannot be changed using string.Replace()?

[Curtis Paul]

Doing this...  

strings.Replace(mac_address, ':', '', -1)

causes this error...

cannot use ':' (type rune) as type string in argument to strings.Replace

What is another way to remove : from a string?

[Brad Fitzpatrick]

Use double quotes, not single quotes.

I tried it with double quotes and it does not remove the : from the string.

[Brad Fitzpatrick]

It returns a new string. It doesn't modify the argument it's given. (It couldn't.)

Your Go installation is broken.

I don't know how.

[Dave Cheney]

Correction: your _gccgo_ installation is broken, or possibly intermingled with other parts of other Go installations.

Dave & Brad,

Blessing upon you both. I just removed Go, both the gcc-go & golang package versions, from my Fedora system. I then reinstalled _only_ the golang* packages. Things are working much better now. I had been having some _minor_ problems, but I figured it was due to ignorance of Go on my part. Those problems have now gone away.
