chapter173, CentOS 8

Next installation from Ubuntu20.04 is the operation verification on CentOS 8.

We confirmed that have been adopted 8.3.1 in g++ on CentOS 8 installed by yum.
Now that we can build the latest C++.

Certainly, the “std::” of the filesystem was to take in C++17 to C++20, so if it was C++11, it has been depended on Boost library.

By the way, the “BOOST_FOREACH” macro can be replaced by the new “for” construct introduced in C++11.

About … “asio”, The “asio” is sure to have needed Boost library even in C++20.

chapter171, Ubuntu 20.04 LTS

We have been building a new nodes, and we installed latest ubuntu 20.04 LTS there.

The installation of the almost library was so smooth, but a verification error occurred with “wget” of SSL.

We just download the “ca” and assign to wget, but no matter how many times we try assign, it’s an error. umm …

wget -q http://curl.haxx.se/ca/cacert.pem -O $HOME/.cacert.pem
echo ca-certificate = $HOME/.cacert.pem >> $HOME/.wgetrc

After thinking about 3 minutes, when we checked the list with “ls -lah”, we noticed that the size of “.cacert.pem” was 0 bytes.

So we downloaded “.cacert.pem” from Windows, transferred it to $HOME, and “wget” worked fine. pleasure!
