Error during make on 5.5.0

[nabeards]

Trying to build with the tag 5.5.0 checked out, and I get the following errors:

CMakeFiles/xmrig.dir/src/base/kernel/Env.cpp.o: In function `xmrig::Env::expand(char const*)':
Env.cpp:(.text+0x813): undefined reference to `std::regex_iterator<__gnu_cxx::__normal_iterator<char const*, std::string>, char, std::regex_traits<char> >::regex_iterator(__gnu_cxx::__normal_iterator<char const*, std::string>, __gnu_cxx::__normal_iterator<char const*, std::string>, std::basic_regex<char, std::regex_traits<char> > const&, std::bitset<11ul>)'

This is on CentOS 7.7. 5.4.0 builds without issue.

[nabeards]

It looks like std:regex_iterator isn't available before gcc 4.9, max available on CentOS 7 is gcc 4.8.5.

[xmrig]

I will add ability to build without env variables support (new feature added in v5.5).
Thank you.

[nabeards]

Awesome, thank you for the quick reply!

[xmrig]

Fixed in master (accidentally commit to it) and dev branches.
Thank you.

[frankfpb]

Thanks all right now. gcc version 4.8.4 (Debian 4.8.4-1)

[nabeards]

Works correctly now.
