xcode5 - Xcode - symbol(s) not found for architecture x86_64 (iOS Lib) -

i building static library. build setting has architectures set to: $(archs_standard) shown standard architectures (armv7, armv7s, arm64) build lib choosing ios device , using simulator (for illustration iphone retina).

now have 2 builds (one within debug-iphoneos , other within debug-iphonesimulator, utilize lipo -create create aggregated lib:

lipo -create path/to/first/lib /path/to/second/lib -o mylib.a

if used library in project simulate on ios device 64-bit architecture, gives symbol(s) not found architecture x86_64. makes me angry lib project within workspace project utilize lib. can simulate on 64-bit ios simulator! (on simulators , devices matter). doing wrong?

notes:

this not duplicate q. before accusing me of (since sec day trying prepare stupid issue), did search on stack , google. answers don't help. i using xcode 5.1.1.

i had same problem building static library. have found basic solution. (you need build universal library x86_64/armv7/armv7s/arm64)

1) click on project file 2) click on target 3) open "build phases" 4) open "run script" 5) add together "/bin/sh" , script below

6) nail "cmd + b" (build project)

7) open product in finder

8) navigate 1 directory ("cmd + ↑"), , see "release-universal" directory.

there "fat/universal" library, ready go!
