Hi all
I would like to deploy my working binary on the cluster. Currently I hit the problem, of different locations of libc, and I am using cargo for the addons.
Is it possible to tell cargo to generate a static binary? It is ok if it becomes a big one.
The error I get from the binary is:
/lib64/libc.so.6: version `GLIBC_2.18' not found
and the libc on the cluster ist
/lib64/libc.so.6 -> libc-2.17.so
Regards dns2utf8
The issue isn’t exactly the location of libc, but rather the version of libc that the binary requires. There are a couple of approaches here.
You can compile your binary on a system with a sufficiently old version of libc - I like to use Docker for this personally.
It’s unfortunately not really possible to statically link to glibc in a reasonable way. If you do want a completely static binary, another option is to use the x86_64-unknown-linux-musl target, which uses musl as its libc instead of glibc and can be statically linked. I believe all you’ll have to do in this case is install musl, install a copy of the standard library built for that target (available here) and then specify that target when you build: cargo build --target x86_64-unknown-linux-musl. I haven’t actually tried this myself, though.
