What steps will reproduce the problem? 1. Create a project. 2. Add the ZipArchive folder with their files. 3. Add the libz.1.2.3.dylib

What is the expected output? What do you see instead? I have all the code (about ziparchive) commented, so i only have the #import "ZipArchive/ZipArchive.h" in my viewcontroller, and i expect to build the project without errors.

I see the following error in the compiler:

ld: warning: ignoring file /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2/Symbols/usr/lib/libSystem.dylib, missing required architecture i386 in file ld: in /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2/Symbols/usr/lib/libobjc.A.dylib, missing required architecture i386 in file for architecture i386 collect2: ld returned 1 exit status Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 1

What version of the product are you using? On what operating system? I'm using xcode 4 a project for the ipad with the 4.2 ipad simulator on a Mac os X version 10.6.7

Please provide any additional information below. I think the problem is with the libz.1.2.3.dylib library, and I have some guest of where might be the problem:

1. The libz.1.2.3.dylib path error is on iPhoneSimulator.platform, it is valid for ipad too?? If is not, which lib could i use for the same purpose with the ipad??

2. I'm not sure i'm adding the libz.1.2.3.dylib lib correctly. What I have done is: right-click on Resources folder -> add files to "myproject" -> search for the libz.1.2.3.dylib and add the 4.2 version of it from the path u could see in the compiler errors. I also try to add to the frameworks folder with the same results.

I'm reading lots of posts about how to fix similar problems but no one could help me.

Any idea of what I have to do to fix my problem?? I imagine is the path but dont know which lib i could use then for the ipad.

Really thanks

i have similiar problem, but in my casae xcode 4.0.1 crashes when trying to build to 4.2 ipad simulator...

I'm using XCode 4.0.2 and can't seem to get past linking errors, libz.dylib is definitely linked in but the build can't seem to see it:
