I was doing some tests with Golang exporting shared libraries that can be used in C and came up with the following: calcLib.go: package main import "C" //export Calculator func Calculator(x int, y int) int { return x+y; } func main() { // Need a main function to make CGO compile package as C shared ..
I’m working on my "master cmake file" which has a bunch of functions. So far I always made static libs & target_link them. This worked quite well so far, but now I want to try Dll. This is a little problematic for me. I create dll using this : add_library("testLibA" testLibaMain.cpp testClass.h testClass.cpp SHARED) now ..
I have a std::vector which need to filled with some random values when library is loaded. but I see it is been reset after library is loaded. Is it because of global and static Library code: static std::vector<uint8_t> g_randomNr{}; __attribute__((constructor)) void generateRandomNrAtStart(void) { static bool firstLoad = false; g_randomNr.clear(); if (!firstLoad) { firstLoad = true; ..
Iam build OpenCV 4.5.4 from source for Android and ABI x64_86, with NDK r21e. Build was success without errors.

I’m building a game with raylib and made my own custom button in different files to reuse it when I need it. I watched tons of videos and read docs but I don’t know why it throws undefined reference to CustomButton::CustomButton(). Here’s the error: /usr/bin/ld: CMakeFiles/AstroX.dir/src/main.cpp.o: in function `_GLOBAL__sub_I_main’: main.cpp:(.text.startup+0xaca): undefined reference to `CustomButton::CustomButton(Vector2, float, ..

I am trying to build a Native (C++) share library in Android studio (it will be linked to another project). I created the Native project, but whatever I try, it seems I have to have at least one java file that calls a C++ API from that library, meaning I need another C++ file in ..
I have a project where I mix between static and shared libs. The shared libs are delivered. Each shared lib is built with its correspondence static lib. A shared lib can depend on other shared libs as well. For example, I have: sharedA, sharedB, sharedC, staticA, staticB and staticC. SharedA is built with staticA inside ..
I have an application that is composed by different layers and written in three different languages: c++, bash and python Since now we are managing different build, platform depending, with different branches of sw development, but I’m trying to merge everything in a single branch to increase maintainability. Do you know if there is a ..
I have created a project that is split into several directories, each of the directories creating a shared library with add_library(${PROJECT_NAME} SHARED ${ALL_FILES}) in CMake. I have a test subdirectory where I use add_executable(${PROJECT_NAME} ${ALL_FILES}) # Dependencies target_link_libraries(${PROJECT_NAME} PUBLIC GTest::GTest Boost::log Boost::json magic_enum::magic_enum <other subfolder project name> ) find_package(GTest REQUIRED) enable_testing() include(GoogleTest) gtest_discover_tests(${PROJECT_NAME}) It all ..
