Made a bash script which I compiled into a binary with shc:

```no-highlight
#!/bin/sh

qemu-x86_64 /root/.cmdstan/cmdstan-2.25.0/bin/stanc_x86_64 "$@"

```

with the earlier stanc binary renamed as stanc\_x86\_64, and then the compiled bash script renamed to stanc. EDIT: Path edited.

Trying to compile once again, and I get this:

```no-highlight
> cmdstanr_example()
Compiling Stan program...
make: *** [make/program:53: /tmp/RtmpE57fTx/model-59645f9ebd62.hpp] Error 1
Error: An error occured during compilation! See the message above for more information.

```

I should also add that compilation with RStan works fine.
