With Xcode 4, if you include the library project into your app project, then you can add this to the Other Linker Flags: -force_load $(BUILT_PRODUCTS_DIR)/<library_name.a> You still need the dependency, and you need to add the library in the Link Phase list of frameworks and libraries too. EDIT: Apple now says as of some Xcode … Read more
Public: The interface is finalized and meant to be used by your product’s clients. A public header is included in the product as readable source code without restriction. Private: The interface isn’t intended for your clients or it’s in early stages of development. A private header is included in the product, but it’s marked “private”. … Read more
I had a similar problem and solved it by setting the lib project as a dependency of the main app project and then setting ‘Link Library Dependencies’ and ‘Use Library Dependency Inputs’ to Yes for the main project. Update: Recently I discovered that Visual Studio 2015 now supports a /WHOLEARCHIVE linker flag. I can’t find … Read more
The visibility(“hidden”) attribute does not suppress a symbol from an object file and cannot prevent a symbol being extracted by nm. It just instructs the dynamic linker that the symbol cannot be called from outside a shared library that contains it. Consider a source file file.c containing your example functions: int f_b1(){ return 21 ; … Read more
All the issues I had, that were giving Undefined symbols for architecture x86_64 were due to the fact that some libraries were compiled with libstdc++ and could not be used for code that is compiled/linked with libc++ libc++ is in fact the default new library used by clang since Mavericks, however it is possible to … Read more
if you want create static lib mean refer the link http://jaym2503.blogspot.in/2013/01/how-to-make-universal-static-library.html Step 1 : Create a New Project, Named it “Logger” Step 2 : Create Classes You can create as many classes you wants, In our tutorial we will create one class named “Logger”. So, now two files should be in our resource. 1. Logger.h … Read more
It turns out my original attempt was mostly there. The following works: extern “C” void Af(void); void (*Af_fp)(void) = &Af; For those that want a self-contained preprocessor macro to encapsulate this: #if defined(_WIN32) # if defined(_WIN64) # define FORCE_UNDEFINED_SYMBOL(x) __pragma(comment (linker, “/export:” #x)) # else # define FORCE_UNDEFINED_SYMBOL(x) __pragma(comment (linker, “/export:_” #x)) # endif #else … Read more
I had the same trouble with building static library. Finally I have found the basic solution. (You need to build universal library for x86_64/armv7/armv7s/arm64) 1) Click on the project file 2) Click on the target 3) Open “Build Phases” 4) Open “Run Script” 5) Add “/bin/sh” and the script below ########################################## # # c.f. http://stackoverflow.com/questions/3520977/build-fat-static-library-device-simulator-using-xcode-and-sdk-4 … Read more
I’ve managed to solve my problem by using the following: #Dynamic/Shared Libs … #Static start set_target_properties(icarus PROPERTIES LINK_SEARCH_START_STATIC 1) set_target_properties(icarus PROPERTIES LINK_SEARCH_END_STATIC 1) set(CMAKE_FIND_LIBRARY_SUFFIXES “.a”) #Static Libs … #Set Linker flags set(CMAKE_EXE_LINKER_FLAGS “-static-libgcc -static-libstdc++”) This works without passing a -static which creates other big issues, and can essentially mix static and dynamic libraries. As long … Read more
LIBS += -L[path to lib] -l[name of lib] Note! that filename of lib: lib[nameOfLib].a and you have to pass only original part -l[nameOfLib]
