dynamic-library

问题 I have some problems with linking my macOS app against C libraries. I have several question related to this issue. It is better to link app against dynamic or static libraries taking into account that this will be very custom libraries rather not shared with other apps? I have linked my macOS Xcode app against ~14 static libraries .a and it works fine. I have reconfigured CMakeLists.txt making this libraries and now Xcode project doesn't work. The main change was changing the directory I have

问题 I experience a crash when I pass a null pointer to dlclose . Should I check for null before calling dlclose ? POSIX tells nothing about this: http://pubs.opengroup.org/onlinepubs/7908799/xsh/dlclose.html Is it undefined behaviour or a bug in dlclose implementation? 回答1: This is tricky. POSIX states that if handle does not refer to an open object, dlclose() returns a non-zero value from which you could infer that it should detect, for an arbitrary pointer, whether that pointer refers to an

问题 I am trying to create and use a .dylib file using gcc. I was going through the tutorial here with my set-up but it does not seem to be working. My directory structure is as follows: src hellomake.c hellofunc.c inc hellomake.h lib libhellomake.dylib I am using the code from here. I tried to compile according to the tutorial with the following gcc -dynamiclib -o lib/libhellomake.dylib src/hellofunc.c -Iinc gcc -Llib -lhellomake -o hellomakesl src/hellomake.c The first command succeeds, and when

问题 I have come across multiple sites describing that frameworks can contain both static as well as dynamic library. But how do I identify if what the framework actually contains is a dynamic library or a static library. I thought of first taking help of extension (.a for static library, .dylib for dynamic library) but all I could see inside the framework that I was experimenting was that no extensions were provided for the binary file that was packaged inside. Is there any way I can find whether

问题 My question seems to be similar to this question however in my case the shared variable is in a static library and also the advice from this question didn't help me: Sharing global data between a shared library and main. Along the way I saw the issues from this question but no final solution either: OS X linker unable to find symbols from a C file which only contains variables. I am trying to make my main process and a dynamic library that it dlopen 's to share the global variable SHARED
