Hello, I hope someone can help me out here. I was in the middle of developing an application on my iPhone before upgrading to 3.0. I followed the general setup given by this example:

Developing for the iphone using the open toolchain and SDK 2.0 headers - antirez weblog

Thus I was actually compiling the code on the phone its self...as this seemed like the easiest option for someone who doesn't own a mac. Now when I try to make my app I get:

/bin/sh: arm-apple-darwin9-gcc: command not found

When I look on Cydia, I can only find "GNU C Compiler" but when I try to install this it shows a depends on libgcc which it can't find (and neither can I when searching for it). Due to this it won't install.

Does anyone have any help to offer? Basic gist is that I want as easy of a way as possible to compile my appliation for my iPhone now that it's running 3.0. I'd prefer to get it working again to compile on the phone it's self, but if I have to switch to somehow compiling on my windows PC I will.

Thanks.

I have the exact same problem. It appears that libgcc is still not available for 3.0 yet. I've contacted several people to inquire about it, but have not heard a response.

It seems that you and I are one of a handful of people in this world that actually use iphone-gcc rather than cross-compiling.

I had the same problem, I just downloaded the libgcc in this website : Section System - iPod Touch ?????? ????????! and now I can install GCC in Cydia

Thanks for the tip! It worked, I was able to install iphone-gcc and after fighting some header file confusion, I was able to re-compile my project. Unfortunately:

/usr/bin/ld: /usr/lib/libSystem.dylib unknown flags (type) of section 4 (__TEXT,__dof_magmalloc) in load command 0
/usr/bin/ld: /usr/lib/libstdc++.6.dylib unknown flags (type) of section 4 (__TEXT,__dof_cxa_runti) in load command 0
/usr/bin/ld: /usr/lib/libSystem.B.dylib unknown flags (type) of section 4 (__TEXT,__dof_magmalloc) in load command 0
/usr/bin/ld: /System/Library/PrivateFrameworks/JavaScriptCore.framework/JavaScriptCore unknown flags (type) of section 4 (__TEXT,__dof_JavaScrip) in load command 0
/usr/bin/ld: /System/Library/Frameworks/CoreAudio.framework/CoreAudio unknown flags (type) of section 4 (__TEXT,__dof_AudioHAL_) in load command 0
collect2: ld returned 1 exit status



It appears to be some linking issues still. Even "hello world" will not build. I'm guessing that libgcc does need to be updated and perhaps it was left off on purpose.

No updates on this topic anywhere on the web that I can find...how is everyone developing on Windows for jailbroken iphones on 3.0? I'd love to be able to get back to finishing up my XBMC remote app.

Thanks.

I got iphone-gcc to work for 3.0. Grab "fake-libgcc" from Cydia. It will provide the necessary pre-req's for iphone-gcc. My old apps now compile and link great!

what repository ?

My bad- I downloaded it and installed it manually. I believe this is the url I found it:

http://files.getdropbox.com/u/876743...honeos-arm.deb

It was written by Ryan Petrich (Clippy author).

Install with: dpkg -i fake-libgcc_1.0_iphoneos-arm.deb

Your r the man !!!
thanks alot !!!!

I tried this solution last night, and after less than 15 min, I was up and running. Flawless.

So, for anyone else trying to figure out how to build on the iphone again, this is your solution right here.

Thanks a ton JeremyGrieshop!

I dpkg the fake-libgcc on the iphone and now when I try to compile a simple hello world program I am getting an error that "stdio.h is not found" same thing with c++ but instead it is complaining about iostream

[kestl]

I'm having the exact same problem as mystikum on a clean restored and jailbroken ipod touch 1G.

Seems like this is a matter of a that could be solved by a symlink, where is gcc and g++ looking for these libraries, and where are they installed by fake-libgcc? If we can find these two locations then we can just link them.

[rpetrich]

fake-libgcc just sets up some symlinks and enables apt to install iphone-gcc; to actually compile you will need headers (which you have to provide yourself)

[kestl]

Thanks petrich, could you tell me where I could get the header files and what to do with them or point me to a link on how to do this. I'm a linux user I've never had to manually configure gcc before, it's just always there o_0

That thing posted above worked for me, thanks!
