Cannot compile version 7.2 on Arch based Linuxes

[xcom169]

SHA3 error during compiling with both make and ninja:

Same error output on a Kali Linux which is a Debian based Linux.

Is this with GCC 12? What is the output from g++ --version?

Trying to compile for Windows (x64) I encountered the same "Sha3Hash.h:18:29: error: return type ‘struct std::array<long unsigned int, 4>’ is incomplete"

I had to Add "#include < array >" to "Sha3Hash.h" file. (**minus spaces between the carats, since GH comments eats the text between carats without those spaces)

I also found I needed to include array in "Gpu.cpp" and "clwrap.cpp" as well to resolve all build errors and successfully compile, in case it is relevant to your Arch woes.

The output of mine is : g++ (Debian 12.2.0-1) 12.2.0

The missing include was merged.

Thanks! I'll try soon.
