Hi all,
I've been scouring the web to understand Perl's build system, but I can't seem to find the info I am looking for.
What I want to do: run a Perl-tool (exiftool by Phil Harvey to be exact) inside an iOS app. On macOS, I can create an app, spawn an new process that runs exiftool using C conventions or using Apple's NSTask, no problem. On iOS however, there is no system installed Perl, nor is it possible to install it (unless jailbroken, but I am not going there). So, no big deal, I read about perlembed (https://perldoc.perl.org/perlembed), and I thought that looks exactly like what I need so let's get it done.
But! As I understand, 'cross compiling' Perl means the following, using some custom autotools configure settings:
1. build 'miniperl' in the target architecture (in my case, for iOS that would be arm64 for devices, and arm64 or x86_64 for the simulator that runs on macOS)
2 Miniperl will build the actual library (.a file), and is expected to do so
on the target device .
This last step is problemematic: on iOS there is no toolchain present, and no way to SSH into it and run miniperl.
So, the challenge: how to compile Perl for arm64 (for iOS devices), and x86_64 / arm64 (for Intel or M1 macOS devices respectively, running the simulator), on macOS without SSH (or any other) access to the target machine for building?
