Thanks! But do you have an alternative library for RPC-calls?

(Asked by: username_0 on 2021-12-23)

I'm trying to install the [libbitcoin-rpc](https://github.com/gitmarek/libbitcoinrpc) but I'm getting the following error when I try to install with `make`:

```
gcc -fPIC -O3 -g -Wall -Werror -Wextra -std=c99 -D VERSION=\"0.2\" -o src/bitcoinrpc_err.o -c src/bitcoinrpc_err.c
src/bitcoinrpc_err.c: In function ‘bitcoinrpc_err_set_’:
src/bitcoinrpc_err.c:39:9: error: ‘strncpy’ specified bound 1000 equals destination size [-Werror=stringop-truncation]
   39 |         strncpy(e->msg, msg, BITCOINRPC_ERRMSG_MAXLEN);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
make: *** [Makefile:87: src/bitcoinrpc_err.o] Error 1

```

I have installed all dependencies and I have also already tried changing the `Makefile` and the `PATH` according to the `README` but nothing worked.

I think the issue is related to [this question](https://stackoverflow.com/questions/59250031/strncpy-gcc-gives-werror-stringop-truncation). Is the libbitcoin library still maintained? Last changes were in 2016 and the `strncpy` error exists only since 2019 I think.
