Gdb build error on Mac #10

Open jacklee-5 opened 3 months ago

jacklee-5 commented 3 months ago

Hello,

I tried to build gdb on Mac M1, but I failed with this error in gcc-14. It seems that gnulib/import/sys_select.in.h needs to be modified ,but I am not sure.

Could you give any advices for this?
