Undefined framework symbols #154

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

1. Successfully build toolchain against MacOSX10.4u SDK and iPod Touch
2.0.2 firmware and filesystem, following issue 141 and patch provided in
issue 145.

2. Compile and link following code:

    #import <UIKit/UIKit.h>
    int main (int argc, char** argv)
    {
      NSAutoreleasePool* autoreleasePool =
        [[NSAutoreleasePool alloc]  init];
      return 0;
    }

    $ /usr/local/bin/arm-apple-darwin-gcc -c main.m -o main.o
    $ /usr/local/bin/arm-apple-darwin-gcc -lobjc
          -framework CoreFoundation
          -framework Foundation
          -framework UIKit
          -o MyApp main.o

What is the expected output? What do you see instead?

I get the following error:

    /usr/local/bin/arm-apple-darwin-ld: Undefined symbols:
    .objc_class_name_NSAutoreleasePool
    collect2: ld returned 1 exit status

What version of the product are you using? On what operating system?

Toolchain built as per wiki instructions with issue 141 and issue 145.
Ubuntu 7.10 on AMD64.

Please provide any additional information below.

It basically doesn't find any of the framework symbols. A couple of months
ago, I had built the toolchain against the same iPod Touch but with an old
1.x firmware and filesystem, and everything was fine then, I could build
and run my application fine.

I can't find something like 
/usr/local/bin/arm-apple-darwin-ld: Undefined symbols:
.objc_class_name_NSAutoreleasePool
.objc_class_name_UIApplication
.objc_class_name_UIHardware
.objc_class_name_UITextView
.objc_class_name_UIView
.objc_class_name_UIWindow

Got the same problem:

-------------------------------------------------------------------------
/usr/local/bin/arm-apple-darwin-ld: Undefined symbols:
.objc_class_name_NSAutoreleasePool
.objc_class_name_UIApplication
.objc_class_name_UIHardware

Can anyone help, please?

P.S. Makefile in attach.

Does anyone have a solution for this problem yet?
I was able to link it somehow before, but now i'm stuck again

Anyone have idea how to solve this?

Is that because the framework on iphone not compatible with this toolchain 
anymore?
I'm using firmware 2.2.1

Thanks, really need a answer

I have the same Problem, i have tested it on 32Bit "openSUSE 10.3" and cygwin 
Windows 32Bit, both exctly the same problem.

I'm using firmware 2.2.1

I have the same problem on cygwin/XP, firmware 2.2.1 (5H11), toolchain built 
against
MacOSX10.4.Universal.pkg, using svn revisions from issue 141 and patches from 
issue 145. 

I notice that the NSAutorelease symbol is displayed when running:

$ arm-apple-darwin-nm
/usr/local/share/iphone-filesystem/System/Library/Frameworks/Foundation.framewor
k/Foundation

38690398 b ___NSAutoreleaseHighWaterResolution
3066ebfc t ___NSAutoreleaseObject
3866cd0c d ___NSAutoreleaseReleaseEnabled

although this doesn't appear to display the ".objc_class_name_*" name-mangling 
prefix
that arm-apple-darwin-ld is looking for. Is there something I'm missing here ?

NB: Issue 117 appears to be a duplicate of this issue.

Sorry, should have included the LDFLAGS from my Makefile earlier:

LDFLAGS = -lobjc \
  -F/usr/local/share/iphone-filesystem/System/Library/Frameworks \
  -F/usr/local/share/iphone-filesystem/System/Library/PrivateFrameworks \
  -framework Foundation \
  -framework UIKit \
  -framework CoreGraphics

which, looking at the command-lines generated in procmon.exe, runs:

C:\cygwin\usr\local\bin\arm-apple-darwin-gcc.exe -lobjc
-F/usr/local/share/iphone-filesystem/System/Library/Frameworks
-F/usr/local/share/iphone-filesystem/System/Library/PrivateFrameworks -framework
Foundation -framework UIKit -framework CoreGraphics -o Example Example.o

[...]

C:\cygwin\usr\local\libexec\gcc\arm-apple-darwin\4.0.1\collect2.exe -dynamic 
-arch
arm -macosx_version_min 10.4 -syslibroot /usr/local/share/iphone-filesystem
-weak_reference_mismatches non-weak -o Example -lcrt1.o
-L/usr/local/lib/gcc/arm-apple-darwin/4.0.1
-L/usr/local/lib/gcc/arm-apple-darwin/4.0.1/../../../../arm-apple-darwin/lib

-framework Foundation -framework UIKit -framework CoreGraphics Example.o -lgcc
-lSystem -F/usr/local/share/iphone-filesystem/System/Library/Frameworks
-F/usr/local/share/iphone-filesystem/System/Library/PrivateFrameworks

[... and ...]

C:\cygwin\usr\local\bin\arm-apple-darwin-ld.exe -dynamic -arch arm
-macosx_version_min 10.4 -syslibroot /usr/local/share/iphone-filesystem
-weak_reference_mismatches non-weak -o Example -lcrt1.o

-framework Foundation -framework UIKit -framework CoreGraphics Example.o -lgcc
-lSystem -F/usr/local/share/iphone-filesystem/System/Library/Frameworks
-F/usr/local/share/iphone-filesystem/System/Library/PrivateFrameworks

... hope this is of use. Tempted to throw in the towel at this point and 
reinstall
the toolchain (*arg*)

Okay, managed to get the example above compiling/running, but ended up using the
instructions at http://www.saurik.com/id/4 using an iPod 2.0 firmware (instead 
of the
1.1.4 mentioned on that page), building against the MacOSX10.5 and iPhoneSDK2_0
libraries. Needed to fix some file permissions and symlinks during the process, 
but
that may have been due to the method used to decompress the firmware.

The arm-apple-darwin9-gcc that's generated from this process will exhibit the 
same
failure as described in this issue ("Undefined symbols:
.objc_class_name_NSAutoreleasePool") if the -fobjc-abi-version=1 flag is passed 
to
arm-apple-darwin9-gcc.  If -fobjc-abi-version=2 is supplied (or if the flag is 
not
present), then the binary appears to compile OK.  

Hope this helps.

Yes, it works fine, i can now compile iPhone 2.2.1 Applications under cygwin.
