I just bought a m2 MacBook Pro running latest Xcode / Sonoma from apple refurbed. I am porting from an older macbook pro/intel chip a project that uses pthread. as this is my first week using the laptop, I recompiled the project but the apple linker does not find the libpthread library. I see it is not included in the installed Xcode. how do I get this library from Apple? regards Dave
