 In NetBSD you will almost certainly need to have a newer compiler installed. 
 Using the example of gcc12 from pkgsrc, one will need to set three
 environment variables before starting: 
+```
 export CC="/usr/pkg/gcc12/bin/cc"
 export CXX="/usr/pkg/gcc12/bin/g++"
 export CXXFLAGS="-gdwarf-4 -Wno-redundant-move"
+```
 
 
 In FreeBSD similarly, using gcc12 from pkg
+```
 export CC=/usr/local/bin/gcc
 export CXX=/usr/local/bin/g++
 export CXXFLAGS="-gdwarf-4"
+```
 
 
 Then continue with the build as below.
