cmake link shared library example

Building a Dual Shared and Static Library with CMake 3# Make the library available system wide. It uses modern CMake. These are typically hard-coded guesses. CMake by Example. When trying to learn CMake I could not | by Mirko AIX ld: 0706-006_iteye_7589- - add_library(my_lib lib.cpp) The CMake variable BUILD_SHARED_LIBS controls whenever to build an static (OFF) or an shared (ON) library, using for example cmake ..-DBUILD_SHARED_LIBS=ON.However, you can explicitly set to build an shared or an static library by adding STATIC or SHARED after the target name: find_library CMake 3.25.0-rc2 Documentation Legacy (non-namespaced) names are still available, for example arrow_shared. Making a library with CMake is not that different from making an application - instead of add_executable you call add_library. GitHub - pablospe/cmake-example-library: How to install a library with See the target_link_libraries () command for meaning of arguments. The convention CMake uses to name the file of your library is as follows: lib library-name .so For example, if you specify "native-lib" as the name of your shared library in the build script, CMake creates a file named libnative-lib.so. I am developing a conan package which consists in an executable and a bunch of shared libraries, which depend on examplepkg. Specify libraries or flags to use when linking any targets created later in the current directory or below by commands such as add_executable () or add_library (). Listing 1 shows the CMake file for a CUDA example called "particles". link two static libraries to a shared library - Code - CMake Discourse CMake Discourse Code os:windows NePutin94 (Dmitry) September 22, 2021, 9:19am #1 The structure of my project: +--ROOT -CmakeLists.txt +--imgui -CmakeLists.txt +--core -CmakeLists.txt +--imgui_glfw -CmakeLists.txt CMAKE_SYSTEM_LIBRARY_PATH CMAKE_SYSTEM_FRAMEWORK_PATH The platform paths that these variables contain are locations that typically include installed software. A Makefile for the simplest shared library - Code::Chunks add_executable (aten_libtorch aten_min.cpp) add_library (torch SHARED IMPORTED) # The next line hard-codes the library path and file name in the executable set_target_properties (torch PROPERTIES IMPORTED_LOCATION $ {ATEN_LIB_DIR}/shared/libtorch_cpu.so) target_link_libraries (aten_libtorch torch c10) Creating Shared libraries and an executable - CMake Discourse The named target must be created by add_library () within the project or as an IMPORTED library . Link a shared library with CMake Link a shared library with CMake 74,851 Solution 1 I think that what you want is to import a library for CMake: add_library(testlib SHARED IMPORTED) set_property(TARGET testlib PROPERTY IMPORTED_LOCATION "/projectspath/LinkTest/TestLib/app/build/intermediates/cmake/debug/obj/armeabi-v7a/libtest-lib.so") CMakeLists.txt include shared Hello.h src Hello.cpp main.cpp It supports compiling the library either as static or shared. This will install and place in /usr/lib. How to link a shared library with GCC and CMake - PragmaticLinux The docs say the following about target_link_libraries (): The named must have been created in the current directory by a command such as add_executable () or add_library (). Features The main advantage of this example is that it is auto-generated . c++ - Link a shared library with CMake - Stack Overflow Let's start with an example of building CUDA with CMake. This also shows how to create an alias target The files in this tutorial are below: $ tree . On a project using a shared library using Qt6, the compiler raise the LNK2001 error unresolved external symbol. I have provided the full code for this example on Github. Remove the link_directories, so CMake picks up the shared library /lib/libcryptoki.so. I am not a CMake expert so I start from the Qt example code here: https://doc.qt.io/qt-6/cmake-get-started.html that I modify to match my requirements. cmake Tutorial => Libraries Instead of a static library we can build a shared lib as well: add_library(test SHARED test.c) Linking libraries to executables with CMake There is an intermediate step (the one involving ldconfig) which takes care of creating some symlinks needed to link against our foo library.. References. In this example the files would be installed in the ~/mylib/install directory: Create and install the shared library's pkg-config file with CMake At this point we built the shared library and installed it system-wide, with the help of CMake. Using the target_link_libraries() statement to control the linked CMake's function for creating a library is add_library, and the code block below shows the usage. and finally, yes, you need to specify PRIVATE <static libs> when linking your shared library, so the linker command line for your executable wouldn't have any static libs zaufi 6349 score:7 As I know, CMake doesn't allow to mix STATIC and SHARED libraries. [Solved] Link a shared library with CMake | 9to5Answer link two static libraries to a shared library - Code - CMake Discourse As a result, namespaced targets are now exported, such as Arrow::arrow_shared. So now we can specify that we want shared libs from SomeLib at the command line with -DSomeLib_SHARED_LIBS=YES or we can enforce it in the CMakeLists.txt by simply setting it. Shared objects for the object disoriented! CMake will build the library as libtest.a and install it into lib folder of the install directory. You only need to change the project name, and add the files that need to be compiled in foo/CMakeLists.txt. Example. Requirements API: C++ 11 or newer, CMake 3.5+ Compiler: GCC, Clang or MSVC About The example is taken from SI, a header-only library that provides strongly typed physical units . cmake-examples/README.adoc at master ttroy50/cmake-examples cmake-shared-lib-tutorial Simple project to demonstrate how to create shared (dynamic) library using C++ & CMake Why Sometimes you can forget something, if it wasn't used long time (or never on practice). It provides cross-platform macros for exporting library symbols, supporting Windows and Linux. AIX CIBA A CMakeLists.txt Right-click on the project in Solution Explorer and select "Launch CMake Debugger": Step to the target_link_libraries () line and check the sqlite3 variable. Program Library HOWTO - The section about shared libraries. Here is the tree view: helloworld What is the proper way to link an .so file in CMake? cmake_minimum_required(VERSION 3.8 FATAL_ERROR) project(cmake_and_cuda LANGUAGES CXX CUDA) include(CTest) add_library(particles STATIC randomize.cpp randomize.h cmake INTERFACE_INCLUDE_DIRECTORIES target_link_libraries But doing just that would be too easy, wouldn't it. A library target name: The generated link line will have the full path to the linkable library file associated with the target. Easily Create Shared Libraries with CMake (Part 1) Apache Arrow 10.0.0 Release | Apache Arrow They way it's being done now is that in a given directory, a shared library is created as: add_library (mylibDirA SHARED <local source files> ) then it's added to the mylibA target: target_link_libraries ( mylibA PRIVATE mylibDirA $<TARGET_OBJECTS:mylibDirA> ) Why you ask? I made a minimal project showing the problem. Change CMake RPATH for a single library while keeping others A minimal example using cmake to create a c++ shared library. add_library(libraryName [STATIC|SHARED|MODULE] [EXCLUDE_FROM_ALL] source1 source2 ..) Firstly, the first parameter to add_library is the name of the library. i.e.. find_library(TCMALLOC_LIB NAMES libtcmalloc_minimal.a tcmalloc . cmake .. make all This creates the libconvert.so shared library file: Install the shared library The final step for installing and registering the shared library on your Linux system, involves running these commands from the terminal: sudo make install sudo ldconfig It compiles projects with compilers like GCC, Clang, Intel, MS Visual C++. Configure CMake | Android Developers If you only need to support non-Windows platforms, then this old email from the CMake mailing list from one of the Kitware developers gives the simplest method. GitHub - c0de4un/cmake-shared-lib-tutorial: Simple project to This is an example linking SDL2. How to link an imported shared library to an - CMake Discourse CMake Best Practices - The book In the main CMakeList.txt cmake_minimum_required (VERSION 3.12) project (GraphicTest) set (CMAKE_CXX_STANDARD 11) include_directories ("$ {PROJECT_SOURCE_DIR}/SDL") add_subdirectory (SDL) add_executable (GraphicTest main.cpp) target_link_libraries (GraphicTest SDL2) and in the library folder. An example being /usr/local for UNIX based platforms. 2.) [ [debug|optimized|general] <item>] .) We also include our public header file into the install step and tell cmake to put it into include. In order to keep the CMake file as small as possible, a few possible optimizations are omitted. Linking a Shared Library Building the Example Introduction Shows a hello world example which first creates and links a shared library. Notably, I stripped any information relating to testing out of the project. [Solved]-CMake link a shared library to static libraries-C++ set (SomeLib_SHARED_LIBS YES) find_package (SomeLib REQUIRED) However, BUILD_SHARED_LIBS is supposed to be reserved for the user and not set by the build. target_link_libraries() .ccpp .so Here is your code with the modifications needed: m.h #include "m_exports.h" int M_EXPORTS m (); m.c cmake -DCMAKE_INSTALL_PREFIX=~/mylib/install .. The problem is, that CMake follows the symlink and then the ldd dependency libcryptoki becomes libeToken - the middleware becomes hardcoded: CMake's add_library - Creating Libraries With CMake c++ cmake shared-libraries Share Introduction to CMake by Example Page Contents [ hide] 1 Introduction 2 Source Code for this Discussion 3 Example 1: The Hello World Example 4 Example 2: A Project with Directories 5 Example 3: Building a Shared Library (.so) 6 Example 4: Building a Static Library (.a) 7 Example 5: Using a Shared or Static Library 8 Conclusions Introduction Other changes Our CMake package files have been overhauled (ARROW-12175). Compiling in release mode now uses -O2, not -O3, by default (ARROW-17436). Creating a C++ library with CMake | Declaration of VAR - GitHub Pages target_link_libraries CMake 3.25.0-rc2 Documentation The project can be found at GitHub: % [ github.com/ashaduri/demo-library-simple] Libraries - A Quick Refresher A library can be either static or shared. In essence, use find_library() to find the location of the actual library, favouring static libraries over shared ones by listing them first in the names to look for. c++ - CMake - SegmentFault -- Install configuration: "" -- Installing: /usr/lib/libPrimeUtil.so -- Up-to-date: /usr/local/include/primeutil.h CMake part 2: Examples to build executable and library projects 30 Mar 2022 Introduction CMake is a cross-platform software for building projects written in C, C++, Fortran, CUDA and so on.
