Questions tagged [i386]

Use i386 tag for questions related to 32-bit implementation of x86 ISA

The 32-bit version of x86 instruction set architecture (ISA) is now called i386, after Intel's first 32-bit processor, the 80386, which is also known as i386.

For general x86 ISA questions, which are not specific to 32/64 bits, use tag instead.

Why does the iOS simulator require i386 and x86_64 symbols even though I'm on an x86_64 system only?

I'm trying to get an app running on the simulator that has had some problems doing so before. We don't have libjpeg.a built for i386, but it does have x86_64. This is the only dependency left, but I'm wondering why I actually need i386 symbols, if…
