recieved apple O Linker Error when adding ASIHTTPRequest

Question

this has made me crazy today, I use ASIHTTPRequest, http://allseeing-i.com/ , already, but here, am trying now to add it to an app, once added it gave me this crazy error.

I have started a new fresh project, and commented all related code, added the code without it, and yes, it works, added it, and it's libraries and no it doesn't work and I got this crazy Error, I'm stuck and need help.

BTW, this is the detailed error,

ld: warning: ignoring file /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libz.1.2.3.dylib, missing required architecture i386 in file
ld: warning: ignoring file /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.dylib, missing required architecture i386 in file

collect2: ld returned 1 exit status
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 1

Thank you, Regards, Ahmed

Solution

I got the answer now. I have copied the older version, a working version of my app. Or just create a new project and add the files that are not related to this, and make sure it's working and building. Then, Added the frameworks from project setting (first icon on left) and then added from the build phase the correct libraries. My problem was : I was trying to add the libraries by dragging them into my project, and the problem was specially for this one. libz.1.2.3.dylib. Thank you anyways, hope this is helpful for someone.
