"bash make.sh" failed

[geekyutao]

Hi Weirui,
I tried to build the depandency but failed. Is there a requirement on GCC version? The log is as belows. I also tried to modify ">>" to "> >", but the "nullptr" problem was still out of there. Did you have any suggestions? Thank you!

Best,
Tao

The version of GCC is recommended to be higher than 7.5. Have you ever tried a higher version of GCC?

Thanks Weirui! It worked when I upgraded my GCC above 7.5.
