[AGENT++] src/asn1.cpp:386:5: error: ISO C++17 does not allow 'register' storage class specifier

[J.R. Heisey]

Correction the clang command line. Same option values apply.
There are also the options "--std=c++14" and "--std=c++03".

https://clang.llvm.org/cxx_status.html
Note that this page uses on dash instead of two for the option.

Thanks,

Claus,

I see "--std=c++17 " on the command line to g++.
I suspect that the snmp++ code is not written to conform to this new standard.
Try "--std=c++11" or "--std=c++98"

Hi,

I have problems to compile snmp++ with newer clang++ compiler

Best regards
