Null status reply #140
Description
This time I'm running a redis-plus-plus client on a different machine than server, However i think i've not installed redis-plus-plus correctly, i tried multiple times and download multiple versions of hiredis to make this work, but every time i compile the client with below command, i get this result as shown below:
root@user-HP-Pavilion-Notebook:/home/user/tests/redisclient# g++ -std=c++11 -o hclient hclient.cpp -lredis++ -lhiredis
/usr/bin/ld: warning: libhiredis.so.1.0.1-dev, needed by /usr/local/lib/libredis++.so, may conflict with libhiredis.so.0.14
and while running the client, I get this error:
terminate called after throwing an instance of 'sw::redis::ProtoError'
what(): A null status reply
Aborted (core dumped)
As my client is using OptionalString so I tried compiling it with -stdc++=17:
root@user-HP-Pavilion-Notebook:/home/user/tests/redisclient# g++ -std=c++17 -o hclient hclient.cpp -lredis++ -lhiredis
