@markmay76 hmm, interesting, can you post the full output of g++ ? also please post the output of g++ --version
Full output of g++

From what I found online, I believe this change is something Ubuntu does different from the normal default. I'm not familiar enough with c++ to track it down, but might be worth mentioning in case others run into it.
@markmay76 thanks, i think i know what it is now. can you run git pull
and re-run g++ src/main.cpp -std=c++17 -lcurl -lpthread
and see if g++ still complains?
That solved it.
Thanks for writing this. It is an interesting way to use some of the storage space.
Thanks Mark

nice :) thank you for taking the time to report it.
btw the count
parameter of dd decides how much space you'll get, eg if you want 90gib, use count=23593750
instead of count=10000
when running dd
When compiling under Ubuntu 18.04 I received the following error:
src/main.cpp:143:110: warning: format not a string literal and no format arguments [-Wformat-security] ){macrobacktrace();error_at_line(status,errnum,FILE,LINE,__VA_ARGS__);}
Not being real familiar with c++, I did some searches and found that I needed additional command line options. I compiled it with the following and everything seems to work: g++ src/main.cpp -std=c++17 -lcurl -lpthread -Wno-error=format-security -Wno-format-security
