问题 Related, but do not answer the question: How do I modify the install name of a .dylib at build time On OSX, I have a dynamic library provided by a packager manager, installed in a non standard directory, which install_name is just the filename. For example: $ ROOT=$PWD $ mkdir $ROOT/foo $ cd $ROOT/foo $ echo 'int foo(int a, int b){return a+b;}' > foo.c $ clang foo.c -dynamiclib -install_name libfoo.dylib -o libfoo.dylib I don't want to change (absolute path, @RPATH, ...) the install_name of

问题 As far as I've searched it appears to be impossible to load modules (=plugins/libraries?) dynamically (I'm very new to React Native..). What I'd like to accomplish is to let the user of the app load additional functions as she/he desires. Example: A user wants to add a music plugin to the app. Intuitively, I'd long for something like dynamic library loading. The user would fetch the library, it'll be loaded into the code and can then be executed. However, in React Native it seems like there

问题 My C++ compiler creates "dylib" files which contain dynamic libraries. Whats the difference between .dylib and .so files? And what is the difference between files in Mach-O format and files in an ELF format? I have to build files for later use under iOS (static libraries only/Mach-O) and Android (ELF). Thanx! 回答1: I found that: One Mach-O feature that hits many people by surprise is the strict distinction between shared libraries and dynamically loadable modules. On ELF systems both are the

问题 I'm trying to build a .dylib in Xcode. Currently the .dylib builds, but when I drag the .dylib into another project and try to #import one of the headers (Seeker.h) in the .dylib, I get this error: *: No such file or directory Seeker.h: No such file or directory The project is available as an Xcode project here. I can confirm the header is indeed in a path alongside the .dylib once built, but as for what to do with it I have no idea. My only experience with .dylib files is frameworks built

问题 I want to run a Qt 5 based application usind dynamic libraries on Linux. In summary, a script will copy the executable and other relevant files, including all required .so inside a lib folder, to the desired destination and a script calling gksudo will work as caller to the app. Till now everything works fine till I call the executable script: the app doesn't run. When I ask to run with sudo , it tells me that a library (Qt5SerialPort...) is missing. Running ldd over the actual executable I

问题 I'm using dlopen to load dynamically generated code. The program calls the compiler on the code and generates a .so file which is then loaded by the program to extend itself. The problem is that if I use the same name for the generated code, the dlopen returns a handle to the old object, not the new one. The code looks like: …generate code into test.cpp system("gcc <args> test.cpp -o test.so"); void *handle = dlopen("test.so"); void *sym = dlsym(handle, "run"); (*sym)(); dlclose(handle); …Do

问题 I want use function 'dlopen()' to invoke a dynamic library on iOS platform, is the function 'dlopen()' private API? 回答1: I've had success using dlopen on iOS for years. In my use case, I use dlopen to load public system frameworks on demand instead of having them loaded on app launch. Works great! [EDIT] - as of iOS 8, extensions and shared frameworks are prohibited from using dlopen , however the application itself can still use dlopen (and is now documented as being supported for not only
