I never compiled under MacOS...

1. looks like a compiler version problem. Which compiler do you use and which version?

too few template arguments for class template 'map'"

2. seems that the sysinfo,h header is missing:

fatal error: 'sys/sysinfo.h' file not found

This header does not exist on MacOS:

https://stackoverflow.com/questions/12523704/mac-os-x-equivalent-header-file-for-sysinfo-h-in-linux

The only reason it is needed is to get the number of CPU cores. You could use sysctl to get them using the HW_NCPU parameter.

https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/sysctl.3.html

To get things compiled fast you could simply set the number of cores manually.

Apple clang version 15.0.0 (clang-1500.0.40.1)

Until now, I built with clang 14.0.6, I just tried with 15.0.6 also, the build went trough fine. Of course the AMD/Intel Version, but the headers should be the same for ARM or AMD/Intel. The only ARM machines I have are Raspberry Pies, I also built with clang 15 successfully.

Sorry but I can't help you out with MacOS.

Do you have a link to the documentation of your std::map version? too few template arguments for class template 'map' seems that your implementation does not have the same set of parameters.
