stack size linker options on MacOS #4

Closed oneilm closed 4 years ago

oneilm commented 5 years ago

For larger multicore problems, my experience has been that the stack size needs to be set as a linker option on MacOS (since the stack size cannot be set to unlimited in the terminal on MacOS). For example, with the flag:

-Wl,-stack_size,0x40000000

This requires changing the macos .inc file, or adding an LDFLAGS variable. Or is this not necessary using the current make file configuration?

Hi Mike, This is not necessary, as there is very little statically allocated memory in the code.
