Cmake link to shared library. c, cpp, etc) are absolutely required when linking in a library. Useful CMake Examples. I am trying to use I have the following layout: top_project + subproject1 + subproject2 Each of subproject1 and subproject2 creates a static library. When creating your executable use the the target_link_library () function to point to your library In this lesson, we'll build our first shared library. This is the behaviour you are seeing. Since the math_oper library is present in a directory outside of the calculator directory, we need to use the This is because CMake expects a SHARED library to always have an associated import library on Windows. Cannot specify link libraries for target "testlib" which is not built by this project. See the current tutorial version here. Linking a shared library is the same as linking a static library. 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(). Specify libraries or flags to use when linking a given target and/or its dependents. Contribute to ttroy50/cmake-examples development by creating an account on GitHub. This article explains how to build your C or C++ application with the GCC compiler and how to properly link a shared library to it. g. I am using CLion, which uses cmake to build its projects. What AutoTools does: builds some static libraries builds some shared libraries and links static ones into shared builds an executable, links it to shared I can't get the additional libraries I am working with to link into my project properly. Step 10: Selecting Static or Shared Libraries ¶ This page was once part of an older version of the CMake tutorial which last appeared in CMake 4. so becomes -lfoo), such as when a shared library is detected to have no SONAME field. On Windows, the compilation is successful as well, main doesn't give any output, though. Usage requirements of a target's dependencies affect This blog will guide you through linking static libraries from subprojects into a single shared library using CMake, with cross-platform considerations and troubleshooting tips. For purposes of this example, the project contains a source file (C++, though Creating a Shared Library with Modern CMake After several days wondering why CMake has to be so dark and complicated, I came across several talks about modern CMake. /usr/lib/libfoo. Besides, what about static library with cmake on windows? I am porting an AutoTools project to CMake. See the target_link_libraries() command for I have a small project with a Makefile which I'm trying to convert to CMake, mostly just to get experience with CMake. It seems that source files (. By default the library file will be created in the build tree directory corresponding to the . 1. Right now, our greeter/CMakeLists. I would like to link these static libraries in a single s 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(). There are some cases where CMake may ask the linker to search for the library (e. Usage requirements from linked library targets will be propagated. By default the library file will be created in the build tree directory corresponding to the This tutorial explains how to develop a shared library in the C programming language and how to generate its build environment with CMake. To do this, find_library () and target_link_libraries () commands are used. I ca This is because CMake expects a SHARED library to always have an associated import library on Windows. In CMake @Florian Does this mean I have to create multiple xxx_exports. On Linux, everything compiles, and running main gives expected output. To see the Static and shared libraries are typically produced from the same set of sources, too, so new CMake users sometimes expect that a single call to add_library will By default if you don't change any RPATH related settings, CMake will link the executables and shared libraries with full RPATH to all used libraries in the build tree. h for every library if I have multiple shared libraries. Below is a simple CMake project. txt defines our library like this: As we learned, when the type is omitted, add_library() defaults to creating a STATIC library.
