Compilation on Fedora 23 fails

[Mebus]

Hallo,

I tried to compile restic on Fedora 23 but got the following error:

My go version is:

go version go1.4.2 gccgo (GCC) 5.3.1 20151207 (Red Hat 5.3.1-2) linux/amd64

Building restic with gccgo is not supported, please use the Go compiler from golang.org. It is available in Fedora 23 as the package golang.

[Mebus]

One can use the "alternatives" command in Fedora to change from gcc-go to golang.

Display current alternatives:

root@hotbox ~ # alternatives --display go
go - status is auto.
 link currently points to /usr/bin/go.gcc
/usr/lib/golang/bin/go - priority 90
 slave gofmt: /usr/lib/golang/bin/gofmt
/usr/bin/go.gcc - priority 92
 slave gofmt: /usr/bin/gofmt.gcc
Current `best' version is /usr/bin/go.gcc.
root@hotbox ~ # 

Change it to golang:

alternatives --set go /usr/lib/golang/bin/go

Thanks for leaving the solution here for others to find :)
