Can't compile with Clang

[spotlightishere]

Since my gcc toolchain does not work, I have to use clang.

It does not allow the '-mthumb-interwork' option to be used, and errors out.

Will support for clang be added, or should I go find another gcc toolchain?

@awesomebing1 The project itself has been dead for a few years now, I doubt anyone will pick it up to be honest, but you never know :)

[spotlightishere]

It is? Didn't know that.

According to Google, thumb interworking is enabled by default. So, I removed that option. Now, it fails at -Ttext=0x0. Don't know what that flag is for, could you please tell me?

Someone should really pick up this project; I still use iDroid on my iPhone 3G... but as to your original question, @awesomebing1, what version of clang/llvm are you using? Why doesn't your gcc toolchain work? I managed to get this compiled from source using the iphone-dev toolchain a while back, did you try that?

[spotlightishere]

I'm using clang 3.6. My gcc toolchain seems to work, but doesn't. It's the one from iDroid-Project/OpeniBoot-toolchain . I truly don't know why it doesn't work, all I know is if you copy an executable over to the device and run it, it gives the annoying "bash: cannot execute binary file" thing. I opened an issue over on that repo, but no replies.

Also, I'm on Linux (Debian 7) with a PowerPC processor. The PowerPC part may be why the toolchain isn't working, who knows :/

@awesomebing1 Why are you trying to run the binary inside of iOS? IIRC it runs directly on bare metal via a bootrom exploit...

[spotlightishere]

Yes, but what I mean is that my compiler doesn't compile right. It compiles, but I can't run the programs on ARM devices (my iPhone 3GS). That was just a demonstration, since I first figured that it may not work after the reboot after uploading.

@awesomebing1 Ah, I see what you mean: I'll take a look and see if I can get a binary to compile right on my x86 Debian machine

[spotlightishere]

I need to temporarily leave due to bad weather. I will be back.

@awesomebing1 You aren't by any chance using arm-elf-gcc from the toolchain to try to compile iOS binaries, are you? I don't think iOS accepts ARM ELF binaries; only Mach-O ones.

My toolchain build does seem to work correctly (just checked the arm-elf-objdump output of some quick hello world code) but it's definitely the wrong toolchain to be using if you want to build userspace binaries for iOS...

[spotlightishere]

I compiled it with that toolchain, and when it rebooted in both recovery and DFU mode I figured it was broke, and build that. So I've solved the iOS part with the GCC toolchain, but what about it rebooting? I compiled the toolchain, and immediately compiled openiBoot with scons iPhone3GS. Then, I used loadibec to upload the .bin file, and it rebooted.

@awesomebing1 The iPhone 3GS isn't currently supported yet and is still very much a WIP, so there could be a number of things going wrong with it. First, is your 3GS bootrom 359.3 or 359.3.2?

[spotlightishere]

The old boot rom, so I would guess the first one.

@awesomebing1 Are you using loadibec from the Chronic-Dev syringe repository?
