[Solved] Unable to make iOS cross compiler

[lebao3105]

I'm on macOS with the latest Xcode installed along with iOS 17 SDK. FPC installed via Homebrew. I want to build a cross compiler for my jailbroken iOS with FPC trunk. I used this command:

Code: Bash  [Select][+][-]

1. $ make distclean all OS_TARGET=ios CPU_TARGET=arm CPU_SOURCE=x86_64 OPT="-XR/Applications/Xcode-15.2.0.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS17.2.sdk" PP=/usr/local/bin/ppcx64
2.  

The process ran fine except the linking part:

Sounds that I'm missing something.

Any ideas?

lebao, I suggest you just might be in uncharted waters here. I'll be watching how you go so please report back.

I have absolutely no experience in cross compiling from MacOS. None. But I do a bit from Linux. You have a large list of unresolved symbols there, that almost certainly means missing libraries. Probably iOS libraries.

When cross compiling to, eg, raspberry pi, I grab a heap of Pi libraries and put them in an appropriate place on my Linux box, make sure fpc.cfg knows where.  So, for you, if those libraries do exist in your MacOS box, perhaps your FPC config file does not know where to look ?  If you don't have those libraries there, then you need them, I have absolutely no idea how you handle that.

I last built cross compilers for iOS and simulator on Monterey x86_64 using below scripts. Adapt for your environment.

The script provided by PierceNg works. It turns out that I've missed linker libraries search path.

To test, I created a simple program that just prints a text line. Compiling it was considered to be pain. Used system's fpc.cfg as dbannon suggests, I added a new unit search path for the newly built rtl package (it's been a while since I last used FPC), also added -Tios (build target) as the compiler somehow said the ppu was built for other platform?

The build success, but when I run on iOS it exits with "Killed" message, returning code 137. I read the compile log and found this:

Code: [Select]

Sorry for the late response, I was in school.

I solved the running issue by signing it with ldid. Thanks everyone for helping me!
