c++: error: the clang compiler does not support '-march=nehalem'

clang-13 FreeBSD 13

FreeBSD is not a supported platform, sorry.

wjakob commented 1 year ago

Hmm, sorry -- I misremembered! Is this still a current issue?

Just got that error; depends what chip you have.

I'm running this on a quartz64a. It has a RK3566 processor. I googled the processor and it has arm A55 cores on it. Googling arm A55, I found the cores have an ARMv8.2-A architecture . As a result, I added this bit to the cmake command.

cmake -DNANOGUI_NATIVE_FLAGS="-march=armv8.2-a" ..
