There is already a snap package in the Debian repos. See https://tracker.debian.org/pkg/snap. If this is the program/version you want, you can simply install it using apt-get install snap

sed -i 's/-Werror//g' Makefile* Not beautiful, but might help.

[kamel]

I copy that but the same error

[kloetzl]

That is weird, to say the least. The make file produces errors because the compiler turns warnings into errors because of the -Werror switch. If that is removed from the compilation process, the errors could be similar but should not be the same.

I know this is an old thread but if anyone has the same problem I prefer to write it here because it is one of the first results in google.

There is a subfolder named "Zoe" in the SNAP folder. To compile snap you have to remove "-Werror" in the Makefile in that folder as well (for example by running the above command in the Zoe folder).

Running make in the Zoe folder first, then running make again in my snap folder fixed the same issue for me just now.
