Assembly on ish #2229

Closed elyasafliloof closed 9 months ago

elyasafliloof commented 9 months ago

Hello, this is my first time in github and my first time using ish. I did a bit of assembly programming on my ubuntu pc, and I wanted something similar on my iPad. I’ve found this app, I installed yasm and vim and wrote “hello world” program. Then, I typed what I usually type on ubuntu: yasm -f elf64 hi.asm and then tried to link it with ld, but it said ld not found, so I searched for a linker to download there. I’ve found lld, downloaded it, and typed ld.lld -o hi hi.asm It created the executable “hi” and when I tried to run it ./hi I got weird output. I don’t really know what I’m doing, I would appreciate some guidance. Thank you.

Hi! iSH supports a 32-bit programming environment. You might have more success with -elf32, perhaps?

Thank you, I guess it works. Do I need to re learn assembly for 32 bit system now? Btw, is ish working on the ipad’s cpu directly, or is it some sort of simulation?

32-bit x86 is similar but not quite the same as x86-64. You'll probably find it to be fairly approachable, though. iPad uses arm64 so iSH runs all code in emulation.
