Help/Support [Theos] Undefined symbols for architecture arm64

[ubyt3x 188 iPhone 15 Pro Max 18]

I'm using the iOS 12.2 SDK from https://github.com/DavidSkrundz/sdks.

Whenever I want to run make do or make clean package, theos fails to compile/link outputting the following error(s):

make do

Doesn't matter if I have armv7, armv7s or just arm64 in the ARCHS. It always fails with symbols not being found.

 

Is this the SDKS fault? How can I fix this?

Thanks!

Says it’s a file format error. I’m not sure this is the answer, but try changing the file from Tweak.x to Tweak.xm and make sure to change it in Makefile too

Also, if you’re not building stuff that depends on iOS 12 refer to @busmanl30‘s answer. Official Theos SDKs should work

Also try ios 11, I didn’t have a problem with that one either, personally I use iOS 10.3 and 9.3

Okay, thank you. I'm new to this and thought I would need the latest SDKs.
