Question with my workspace

[star0w]

hello, I have met difficulties when using this code in my computer. Hope u can help! Maybe this is related to gcc version or C++ 17? Could you share more information about the version of cmake and gcc? thx!:)

Yes, it seems to me is related to gcc version. shared_mutex is available in g++-7 and newer version.

Sure. I tried to update my gcc /g++ version from 5.8 to 7.5, however, it seems to be useless. Are there any other possible solutions for this? :( THX!
