iOS 4.2.1 - _abort() food.c:43 - reopened
Hi, this is follow up on the issue #26: https://github.com/comex/frash/issues/closed/#issue/26 which was closed by mistake by kernell, ric.
Again last reply before mistaken close:
*** Warning *** Even I have decades experience with development on various platforms/languages I am complete rookie in Mac OS/ iOS world ... so forbid any inaccuracies or other bulls_t I put below _
Ok guys, I got tired googling all over internet to get same output on this one -> means nothing, everyone just complains it doesn't work, none analyzes. Thus I had checked the source code of Fresh - food.c - line 43 - as some add function trying to lookp and initialize needed libraries - and here it is failing. So I scanned my /usr/lib and really some of referenced libraries were not found (also libraries referenced by other libraries), here is status update on my 4.2.1 iPad iOS:
-
can anyone who is responsible for maintaing this git source add better error handling -> i.e. instead of dummy abort message display which library failed to load ...
-
In the latest source code there is following sequence:
add("/usr/lib/libcrypto.dylib"); ----> don't have it
add("/usr/lib/libssl.dylib"); ----> don't have it
add("/usr/lib/libm.dylib"); ----> don't have it
add("/usr/lib/libSystem.B.dylib"); ----> don't have it
add("./libcutils.dylib");
add("./libutils.dylib");
add("./libgccstuff.dylib");
add("./libicudata.42.1.dylib");
add("./libicui18n.42.1.dylib");
add("./libicuio.42.1.dylib");
add("./libicule.42.1.dylib");
add("./libiculx.42.1.dylib");
add("./libicutu.42.1.dylib");
add("./libicuuc.42.1.dylib");
int fd = open("libflashplayer.so", O_RDONLY);
So as you see already 1st 4 libs were missing + anaylyzing the other libraries I also found other once also missing -> mainly libcrypt ang libgcc.
Then I remind myself when trying to add GNU cc comipler from cydia I was facing issue that libgcc was missing -> whatever are the reasons.
So reason for this problem is clear, question is if we can solve it or not, I started playing around and did:
A) I got libgcc and installed it from following repo (hope I am not mistaken as I tried too many repos recently :) - http://theworm.altervista.org/cydia/ - btw reffered from this thread http://modmyi.com/forums/iphone-ipod-touch-sdk-development-discussion/655111-compiling-iphone-3-0-a.html - other approaches are mentioned -> but read whole thread 1st !!!)
B) after that I was able to install bigboss GNU cc (and othe GNU libs) from Cydia ... I run gcc -> runs ok ... didn't tried yet to compile and run anything ... I looked into /usr/lib and saw lot of missing libs is now there -> sounds promissing ...
C) got also header files refered from: http://antirez.com/page/iphone-gcc-guide.html - so I can start playing around whether the gcc will even work installed this way
Next plan:
- test whether GCC can compile hello world app and run it
- test whether the header files allow me to compile Frash-0.02 on the ipad directly ...if not -> then I'll try Xcode on Max OS ..
- based on source code analysis of food.c check every referred library (and the libraries referred by the lib itself). If I could compile Frahs -> i'll try to add better error message stating which lib failed to load ...
I am busy man so if you can try to play around and post results here I'll appreciate it .. and dozens of other "iPad flash hunters" I guess ...
Cheers

But, what if you take those missing .dylib from an old firmware? Frash works fine in version 3.2.2, so it must have those files to work properly.
i wonder if comex would know... .-. he has a twitter account http://twitter.com/comex
Pretty sure the missing libraries are actually in the dyld shared cache.
Nevertheless if they are there or not ... Frash doesn't see them, that's why it's failing with abort message
Some findings: I've an IPhone 4 with 4.2.1. Frash installed, of course I'm getting error @ food.c line 43. I checked if the missing libraries were not there, and the 4 mentioned weren´t
add("/usr/lib/libcrypto.dylib");
add("/usr/lib/libssl.dylib");
add("/usr/lib/libm.dylib");
add("/usr/lib/libSystem.B.dylib");
=>Added the first two libraries and libgcc from the repos below, Tried Frash and still got the same error. => Since I've a working Frash in one Iphone 3GS running with IOS 4.1, I went there to fetch the two missing libraries. However, to my surprise not all the libraries were there!!!
So I guess we need to try compiliing and adding a more descriptive error message?
Yup, you have to add all libraries the Frash is trying to load including the ones which are referenced by those listed ... so yes we need to improve the error message sent back .. i had problem to make any C code compiled on the phone directly so now trying to learn xcode if it brings something ... if anyone has a step-by-step scenario how to make gcc working on 4.2.1 iOS (including setup of the header files) please help ...
Still, what I do not understand is why Frash is working properly in IOS 4.1 without the last two libraries:
add("/usr/lib/libm.dylib"); add("/usr/lib/libSystem.B.dylib");
But ok, I guess the path is improve the error messages to debug it...
How about going down the list of required dylib(s) and getting the ones missing, then paste them into /usr/lib ? Probabally a stupid idea, but just curious.
Oh and by the way, http://modmyi.com/forums/file-mods/745028-frash-error-abort-food-c-43-a-2.html
Hello everyone!
I am going to post everything that has happened recently on the fourm above with the porting proccess.

Hello!
I just happend to bump into your thread. I am working on making Frash for iOS 4.3.1 . I will be porting it and building probably tomorrow. (Not that it will be finished tomorrow, but some progress will be made! lol)

Ok. So, this is a Quote from Comex's GitHub Page.
To actually run it, you'll need libflashplayer.so from Android.
Build instructions: (do networkpx Project Blog: Compiling iPhoneOS (3.1) apps with Xcode 3.2 without Provisioning Profile but use my version of ldid2) (do http://sumgroup.wikispaces.com/iPhone_Dynamic_Library) ln -s /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk /var/sdk export PATH=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:$PATH cp -a /System/Library/Frameworks/IOSurface.framework/Versions/A/Headers Player2/IOSurface cp -a /System/Library/Frameworks/IOSurface.framework/Versions/A/Headers food/IOSurface cp -a /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreText.framework/Versions/A/Headers food/CoreText cp -a /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.3.sdk/System/Library/Frameworks/IOKit.framework/Versions/A/Headers/ food/IOKit

probably a bad reason

Can someone explain what this does specifically? I think I know, but not sure. Don't want to ruin my new shiny Xcode 4. LOL

Ok. Here are the errors I am getting.
Can someone please explain this? One of them is a file is missing. I have looked over the ENTIRE source code I downloaded and I cannot find any file!
The others might be resolved once we have the other file.
Thanks, The iSmooth Project.
Ok, nevermind! I just fixed all of the bugs above. Now this is what I am having trouble with.
Thanks, The iSmoothProject.
Hello Everyone!
Please ignore all of the bugs above, I just found the files and downloaded them and put them where they belong.
So now, it is making it work for iOS 4.3.1!
I was reading somewhere that system files in 4.1 don't exist anymore, so we need to find them and make a debian that installs them safely.
Here is the link: https://github.com/comex/frash/issues#issue/28
This is a very helpful link.
Thanks for all of your continuing help! The iSmooth Project.

What's Jailbreak?
Join Date: Apr 2011 Posts: 3 Thanks: 0 Thanked 0 Times in 0 Posts Sorry if I misunderstood but I am imagining you will be providing a new frash.deb file to be uploaded to the iPad to work with OS iOS 4.3.1. Is that right ?
I have a iPad iOS 4.3.1 and I tested frash.deb versions 0.01 and 0.02 and it not worked.
My understaning of this topic is to give ways to make Flash work with iOS 4.3.1 right in iPad, iPhone, etc..., right ? If positive should we expect a guide to do that ?

Yes, I will be making a debian file and will be on modmyi repo. It will be as simple as: install in cydia, and it works!
That is my goal! It will be called "Frash4iOS"

Join Date: Apr 2011 Posts: 3 Thanks: 0 Thanked 0 Times in 0 Posts Please allow me my latest stupid question. I just signed into this forum so I'm not familiar with it. What you mean with "my modmyi repo" ? Is it some kind of download page inside the Web Site ? When do you expect to have the "Frash4iOS" available to users ?

This website, modmyi has a cydia repo (you know what repo is, right?) and I will publish "Frash4iOS" on it.
For the second question. 2 weeks? That is what I am hoping for. It could be longer and when it is public, it will be a little buggy of course, but it should be soon!
Ok, I cannot get on my mac because someone else is using it, but I am on my linux server so I will be able to do some things! (The Linux server is running my custom linux operating system. SO SWEET AND FAST! lol)
Anyway, so this is what I am looking for.
/usr/lib/libcrypto.dylib /usr/lib/libssl.dylib /usr/lib/libm.dylib /usr/lib/libSystem.B.dylib
I am going to be jailbreaking an old iOS 4.0 firmware and unzip it to get these system files that frash needs. These are not in the latest firmware so I will get them, put them on my device, and see what happens! lol
When we publish Frash4iOS, we will include these in the debian obviously.

You have a github account? Lol no news yet! I might be able to do it tuesday.
OK thank you all for everything i respect all the developers and programmers and who works so hard to make everything nice and easy for us
they said knowing or understanding the question is half the answer
the question is what is the difference between iOS 3.xx and the new iOS 4.3.x ?
I'm not a phone developer or anything i'm just a pc programmer with some knowledge.
anyway from all up i understood that the new iOS 4.3.x does not support or use the lib that are missing in the Frash
if that's right then i think if we put the missing lib in the new iOS 4.3. it maybe not going to work.
so we need a new Frash that does not based on the old lib and it can works with current lib in iOS 4.3
to do that we need to understand how Frash actually works.
Can you make the new iOS 4.3 to work with old lib?
or You need to build a new Frash?
comex said he will works on that issue but not right now
Good Luck guys Thank you all
Hi all,
Managed to compile a new food.c to try debugging at which point the problem was happening - e.g to know the lib that was causing the trouble. Just installed frash from scratch and replaced the food executable with the new one I compiled.
I found that frash was crashing at the lib ("./libutils.dylib") The lib was present so I checked the dependencies:
libutils.dylib: libutils.dylib (compatibility version 0.0.0, current version 0.0.0) libcutils.dylib (compatibility version 0.0.0, current version 0.0.0) /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.1.0)
I had all of them on my IPhone 4 running IOS 4.2.1, except libz.1.dylib. and libstdc++.6.dylib. I installed libstdc++.6.dylib from Cydia (there's a package with just the symlink) I tried copyng libz.1.2.3.dylib from the IPhone platform SDK (and made a symlink to libz.1.dylib)
Tried running frash and still was throwing error at that d... library (libutils). I could not understand why.
Gave one last try and compiled a new food executable removing the call to add the library and.... VOILÀ!!!! Frash STARTED WORKING as before but now in iOS 4.2.1 on my iPhone 4!!!!!
I got very exited and tried it as well on my iPad 2 running iOS 5.0.1. Got an "Unexpected Error" in the frash window.... to be further analyzed....
This is wonderful!!! Hopefully the unexpected error is just a little bug that can be squashed! :)
Good luck and keep up the great work!

Update: works on iPad1 IOS 4.2.1 as well.
Just installed stock Frash from Repo and changed the food file with the one I compiled without the add libutils line. Worked fine without needing to install the libstdc++ and the libz dylibs.
It would be interesting to test it in IOS 4.3.x...
Sure, I'll send it in a separate email. Please let me know yr results

It did not work for me on iOS 4.3.x, though it does no longer fail at _abort().
Anybody working on this problem ? Or we can forget about flash on ipad ? Abandon all hope all who entered thee ))) ?
In reply to jpla: it did not work for me on 5.0.1 iPhone 4s, nothing happened at all
