After running

```
./zcutil/build.sh --disable-rust

```

I get the following

```
checking whether to enable maintainer-specific portions of Makefiles... no

checking compiler gcc -m64 -pipe -O1 -I/zcash/depends/x86_64-unknown-linux-gnu/include ... no, program does not run

```

Everything prior seems to run.

checking gcc version gives:

```

```

Any advice much appreciated.

Thanks 🙂

Can you post the contents of `config.log`, please? (It’s sufficient to post the part that has the gcc error message.)
