This is the command I am running to install Debian packages from the virtual repo I have created. This repo has library A that contains a shared library and library B that starts the executable that uses this shared library in postinst section of Debian. Library B depends on Library A ( via control file ..

Initial Situation Say I have a project named kitten. For this project I need to link an external, shared library meow with either no or bad/ancient CMake support. For some reason I decide to not simply make adjusted rules for linking and copying the required files for this very project, but rather want to create ..
I’m building a shared library using cmake. Here are the steps that I take, starting with building a shared library A_shared using an object library A_obj. add_library(A_obj OBJECT ${A_SRCS}) add_library(A_shared SHARED) target_link_libraries(A_shared PUBLIC A_obj) This process works. Now I wish to build another shared library that uses A_shared and its own sources. So I have: ..
I have a MATLAB function that I saved in a .m file of the same name: function a = addmtx(a1, a2, f_callback) a = a1 + a2; f_callback(a1*2, a2*2); end then I compiled that .m file as a c++ shared library by matlab Library compiler. The compiled addmtx.h header for C++ has the following function: ..
I am experimenting with Python3 calling C++ Functions from a Shared-Lib. #!python3 # C : nm -gD /usr/lib/libshared.so # C++ : nm -gDC /usr/lib/libshared.so from ctypes import CDLL slibc = ‘/usr/lib/libshared.so’ hlibc = CDLL(slibc) try: hlibc.foo() except: print(".foo() not found") try: hlibc._Z3foov() except: print("._Z3foov() not found") result: .foo() not found echo from shared lib!!! So ..
I’m trying to create a "gaming platform" that lets the user choose a game to play and also the graphic library to render it. Those games and graphic libraries are implemented as dynamic libraries, loaded at runtime. We’ll call the gaming platform Core. The shared libraries contain classes that are loaded at run-time with RTLD_LAZY ..
There is this function which I want to implement into my code. https://docs.microsoft.com/en-us/previous-versions/iis/smooth-streaming-client/compress-function I have included the header file, but as it should be, I receive a linkage error saying that the symbol for this function is undefined. Where is the library for this function? I have searched through many search results and cannot find ..
I want to write a shared library and I want to get a compiler/linker error if I forgot to implement some functions. Consider the following case: test.h class Test { public: Test(); }; test.cpp #include "test.h" main.cpp #include "test.h" int main() { new Test(); } If I create a library with this command gcc -c ..
I encoutered an issue when build Boost-required project via cl.exe on Windows which is the compiler cannot find the libboost_serialization-vc142-mt-s-x64-1_75.lib and after searching i found this is a static library and i built the Boost by default which produces the shared library(at least i suppose to be, please point me if it isn’t) libboost_serialization-vc142-mt-s-x64-1_75.lib, hence ..
(I know various iterations of this question are asked here routinely but I didn’t find anything that helped) I’m trying to write a simple dynamic library and load it at runtime. The library files: mul.h int mul(int a, int b); mul.cpp #include "mul.h" int mul(int a, int b) { return a * b; } Then ..
