Error: “File was built for archive which is not the architecture being linked (armv7s)”
I ran into a similar problem myself. @graver‘s solution is definitely valid. The issue was that the library was being built for armv7 instead of armv7s. You can verify this yourself by using lipo <path/to/lib.a> -info. Setting the Build Active Architectures Only option to No fixes the issue. Hope this helps.

Just incase you cant find HEADER_SEARCH_PATHS … Read more
“undefined reference to” errors when linking static C library with C++ code
But everything works well with other C programs linking this library. Did you notice that C and C++ compilation create different symbol names on object file level? It’s called ‘name mangling’. The (C++) linker would show undefined references as demangled symbols in the error message, which might confuse you. If you inspect your test.o file … Read more
core data in a static library for the iPhone
Sascha’s answer got me on the right track. Merging a compiled .mom file from a static library into the .mom file from a host project was relatively simple. Here’s a trivial example: Create a new XCode Static Library project called MyStaticLibrary Create an .xcdatamodel file in MyStaticLibrary called MyStaticLibraryModels.xcdatamodel, add some Entitys, then generate the … Read more

Xcode custom build configuration causes “library/file not found” for static libraries
As said in similar question iOS Static Library as a Subproject of a Project That Has Custom Build Configurations?, the fix is to add this line $(BUILD_DIR)/Release$(EFFECTIVE_PLATFORM_NAME) to your target’s Framework Search Paths, Header Search Paths and/or Library Search Paths

What’s the difference between `-fembed-bitcode` and BITCODE_GENERATION_MODE?
When you build the library normally, with ENABLE_BITCODE=YES, Xcode adds the build flag -fembed-bitcode-marker to any clang invocation, placing an “empty” bitcode in the final o file. So, if you look to the compile action in the build phase, it will look something like: CompileC {build_path}/StaticBitcode/StaticLogger.o StaticBitcode/StaticLogger.m normal armv7 objective-c com.apple.compilers.llvm.clang.1_0.compiler cd {path}/StaticBitcode export LANG=en_US.US-ASCII … Read more
