Re: Specifying a binary's base address

It might be better to set the pagezero_size to 64KB for 32 bit versions of your main executable. That will ensure that nothing gets loaded there, whereas if you set the image_base, some other library could get loaded below your executable (unlikely but possible.)

Note you won't need to do this for 64 bit programs since there the pagezero_size is 4GB by default (to catch bad pointer math that zeros the top 32 bits of a pointer...)

Jonas, can you use the -image_base linker option? This option was called -seg1addr in the past. Explicitly setting the __TEXT load address should accomplish the same thing but the -image_base option was designed for what you're doing.

Ah yes, that works as well! I hadn't tried it, because the ld man page states that it's only for dylibs and bundles.

Thanks!
