static-libraries

I'm trying to build a project using a static library, so that the binary can be used even if the library isn't installed. However, I get lots of errors about undefined symbols when I try to do so. Looking at the library, I see it has tons of undefined symbols, even though it's a .a static lib: nm - u /usr/local/lib/libthis.a .... U EVP_DigestFinal_ex U EVP_DigestInit_ex U EVP_DigestUpdate U EVP_MD_CTX_cleanup U EVP_MD_CTX_init Those seem to be from openssl; others seem to be from libbzip2; etc. Questions: 1. Why does the static ( .a ) lib have dependencies on shared objects (e.g. libopenssl)

I've been trying to build up a set of reusable libraries for app development, but I'm starting to run into a problem. One of my static libs is a set of general use methods (categories on Objective-C Foundation classes to improve their usability) which I tend to use in every project. (We'll call it Lib A... i.e. XCode project A produces libProjectA.a) Then I have other static libs, things that contain specialized code for math, etc. (We'll call it Lib B.) Lib B links to Lib A because it needs to use some of that general functionality. (i.e. XCode project B links with libProjectA.a and produces

Recently I have started writing test case for one old static library. I have loaded the library to Xcode 5,Since Static Library is old , I have to manually add TestProject with Test Target. When I am trying "Product-->Test" , It launches emulator and Console shows following error The test bundle at /xxx/xxx/xxx/StaticLibTest.xctest could not be loaded because an unanticipated error occurred: Error Domain=NSCocoaErrorDomain Code=3587 "The bundle “StaticLibTest.xctest” couldn’t be loaded because it is damaged or missing necessary resources."

I have created a static library following this link . But I am facing Problems in using the library. For reference on how to use static libraries in an iPhone project I followed this link . But I am stil struggling with the "How to implement static libraries in any other iPhone project?" question. Thank you all. You can use cross-project referencing as in the posts but this has several downturns. I use this setup that works on Xcode in general (not only for the iPhone) and adds compile-time static library version control. I put my static libraries in ~/Library/MyLibraries/, the .a archive

Why exactly is it that when I create an iOS static library project or framework project in Xcode, I don't need to link any iOS SDK frameworks to the project in order to make use of their headers and objects -- for example, I can #import <AudioToolbox/AudioToolbox.h> and put AudioToolbox code in the static library or framework without actually having AudioToolbox added under "Link Binary with Libraries" in build settings or having it present in the file navigator, and the project will build without issue, something that wouldn't work in an app project -- but when a developer then uses the

I'm running gradlew to compile an Android app that has a static lib dependency. Somehow, I have an undefined reference to bsd_signal . I was able to compile this app with gradle 1.X, but I've been obliged to switch to gradle 2.10 and to drop my Android.mk file in favour of putting more build instruction into my gradle.build file, and this is where the trouble arises. Can anyone tell me whether there is a library that defines bsd_signal , which I should link to my project?

Say I have libA. It depends on for example libSomething for the simple fact that a non inline method of libA makes a call to a method in libSomething.h. How does the dependency link up in this case? Does libA have to statically link to libSomething when it is compiled, or will a user of libA (an application using libA) need to link to both libA and libSomething? Thanks Static linking is just copying the whole items (functions, constants, etc) into the resulting executable. If a static library's code contains references to some shared library items, these references will become dependencies in
