/usr/lib/libc.dylib load command 7 unknown cmd field

[GoogleCodeExporter]

What steps will reproduce the problem?

Trying to compile LLVM-GCC
make LLVM_VERSION_INFO=2.0-svn-iphone-dev-0.3-svn 

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

/usr/local/bin/arm-apple-darwin-ld:
/usr/local/share/iphone-filesystem/usr/lib/libc.dylib load command 7
unknown cmd field
collect2: ld returned 1 exit status
make[2]: *** [libgcc_s.dylib] Error 1

What version of the product are you using? On what operating system?
I am using Ubuntu 8.04.
IPhone filesystem is 2.0

Please provide any additional information below.
I have tried this few times and getting same error again.
HEAVENLY and LLVMOBJDIR variables are properly set.
I am searching net since last 7-8 days but no solution till yet.
Please help me in resolving the issue.

Ok. I was successful in building on both 64 bit and 32 bit systems with the
MacOSX10.5.sdk and MacOSX10.4u.sdk

Here is what you need to do:
1. Once you have checked out the iphone-dev  trunk repository using svn do the 
following:
$ pushd include

$ svn switch http://iphone-dev.googlecode.com/svn/branches/include-1.2-sdk

$ popd

$ pushd odcctools

$ svn switch http://iphone-dev.googlecode.com/svn/branches/odcctools-9.2-ld

$ popd

This will give you the updated odcctools and include directories that work 
correctly.

2. Once you get to the llvm-gcc-4.0-iphone compilation stage and are doing the 
make,
then you will see errors if you use MacOSX10.5.sdk. These errors do not come up 
if
you use MacOSX10.4u.sdk. hence if you use MacOSX10.5.sdk, you need to copy the
usr/sys/cdefs.h from MacOSX10.5.sdk and copy it as
/usr/local/arm-apple/darwin/include/sys/cdefs.h .

3. Next step is to patch lib1funcs.asm using the patch file lib1funcs.asm.diff
provided in issue 145, and patch the 
llvm-gcc-4.0-iphone/gcc/config/arm/lib1funcs.asm
file using the command
patch -p0 < lib1funcs.asm.diff

4. Then run the make command again and everything should build perfectly.

Ok. I did what you suggested but still getting errors . This time even in 
compilation of odctools
It looks very wierd. I checked Object.h in odcctools/include/foreign/objc
 directors and it doesnt look good. I have attached the file . Can you please look 
into that and see if its the same on your machine .

Simple man, you do not have gcc-objc installed. These errors occur if you do 
not have
the objc libraries and headers and compilers installed on Ubuntu. Do an apt-get 
or
use Synaptic and install them and retry the make command and you should be fine.

Got  the same issue - gcc-objc are installed. I'm using Mandriva 2008
