undefined symbols for architecture arm64 (6)

After struggling with this same problem and following all the accepted answers of updating build settings, clearing the linker search path, etc.. I finally discovered an answer that worked for me.

Before building, make sure you select right type (iPhone Simulator) instead of iOS Device. Then rebuild. Otherwise, you're trying to use a library built for an iOS device (arm processor) on a simulator on your mac (i386). Should've been obvious, but wasn't.

Undefined symbols for architecture i386: I installed gcc-4.9.2 and tried using it instead of the default gcc, with no luck. I tried using x8664-apple-darwin14.0.0-g-4.9.2 and that did not help either. Mar 27, 2015 Greetings All, I am new to the forums here and hoping to find some assistance from folks that have experience with compiling older FORTRAN code on OS X. I am using the gfortran compiler on Mac OS X 10.9.5 with Xcode version 6.2 and the Xcode command line tools installed. I am performing.

Now, look in the Products group in the Navigator > right click your static library (.a file) > Show in Finder, you'll notice that its in a Debug-iphonesimulator folder instead of Debug-iphoneos. I didn't pay any attention to the folder name originally, or I might have thought of this sooner.

Hope this helps.

I got to build static library. I want to use in my iPhone and ipad app. When I try to run the simulator I get linking errrors. I am new to iOS development. kindly help;

ld: warning: ignoring file /Users/valuelabs/Desktop/DruvaProject/libraries/libnetUtils.a, file was built for archive which is not the architecture being linked (i386) Undefined symbols for architecture i386:
'_OBJC_CLASS_$_netUtils', referenced from: objc-class-ref in ViewController.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I tried adding i386 in the Architectures. but no luck

Had the same problem, and tried diverse solutions from the page to no avail.I still had a message telling me my library was not build for arm64.

Finally how I resolved it :

  • opened the project.pbxproj for the library in a text editor
  • searched for VALID_ARCHS
  • there were 4 occurrences, 2 of which did not contain arm64
  • I manually added arm64 in the chain (VALID_ARCHS = 'arm64 i386 armv7 armv7s')
  • rebuild the lib and it was all right

Seems sometimes the build settings displayed by XCode is incomplete, and doesn't correspond precisely to the project file.
