Setting The Stack Size to 16MB (0x1000000)
Using XCode:
Add -stack_size 1000000 to the Other Linker Flags field of the
Build Styles
pane.
I did this, but I get the following errors when I try to build:
powerpc-apple-darwin8-g++-4.0.1: 1000000: No such file or directory
powerpc-apple-darwin8-g++-4.0.1: unrecognized option '-stack_size'
Does anyone know how this is supposed to work?
Use -Wl,-stack_size,1000000 instead. Also, I'd suggest filing a bug
report against the Q&A to get it corrected.
Also, if you have multiple flags you want to put into
OTHER_LINKER_FLAGS,
how should they be separated - spaces, commas? And how should the
flags be
separated from their values - spaces seem to work, but in other
places (e.g.
compiler flags) I've seen no space, e.g. -O3.
"-O3" is actually a complete flag, not a flag and a value, but that's
a technicality. In general you use spaces to separate commands, but
when passing arguments through from one part of the build process to
another (e.g. -Wl or -Wa) you can use both. For example,
-Wl,-stack_size,1000000
is the same as
-Wl,-stack_size -Wl,1000000
because they're being passed through from the compiler to the linker,
but you can't do this:
-O2,-Wall
because those two flags get handled by gcc itself.
In other words, when in doubt, use spaces.
