The problem here is that dynamic libraries have to be generated with position independent code, so that they can be loaded dynamically into the address space of an existing process. The behavior is the same. 0. I've got a project that looks like this Hi, I am trying to (cmake) compile a binding to a library that uses a another library (dlib). CMake: Linking Fortran against static C library fails. See the INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE target property to exclude items. target_link_libraries(prog funccpp_lib funcc_lib) In CMake and several build systems directly linking a static library into another static library is meaningless. Specify additional link directories for CMake's find_package() on linux. You # can link multiple libraries, such as libraries you define in this # build script, prebuilt third-party libraries, or system libraries. txt adds imgui The main objective with this question is to write an CMakeLists. Some linkers will only search later listed libraries for symbols they have already seen and won't search for an unknown symbol encountered in a library in libraries listed earlier (although some will). native-lib # Links the target library to the log library # included in the NDK Adding -static to target_link_libraries(my_executable lib1 lib2 -static) When I run CMake in VERBOSE=1 mode, it always ends the linking command with: Link static library using CMake. Now I have some third party static libraries to link to libtest. CMake - Creating a static library. The -L option specifies a directory to be searched for libraries (static or shared). And this will only work on systems where the library is actually named libjpeg. So you would set it like this, where MyLibrary is the name of your project: target_link_libraries(MyLibrary -static-libgcc -static-libstdc++) I cannot get the library ${static_library} to statically link using CMake. 0 Linking a static library to a shared library in cmake. a files, regardless of the existence of . 501. c) target_link_libraries(myexe PRIVATE bar) Hi, what is the correct way to add some linking flags whenever a certain static library is used when linking an executable? Example: there is a static library L (providing its own public include directories and maybe depending on other libraries); whenever L is linked into an exectuable, the reference to L shall be enclosed in an -Wl,--whole-archive / -Wl,--no-whole When the library is built as a shared library, we get SomeLib-shared-targets. So I would like CMake to compile the static library (prj1) before the other (prj2) and then link the static library. but at least it is a minimal project that demonstrates my problems with linking to the static library. Targets that are shared libraries, modules, or executables need to use the LINK_OPTIONS target property. That is normally fine. I have a project where there is 1 static library (A) and 1 executable (E) Linux, Ubuntu 24. run something like ar rcs hugelib. cu | cudalib. My question is how to link that into the library i create here. Consider two source files: test1. I have tried hard coding the path and as far as I'm aware TARGET_LINK_LIBRARIES should link this in automatically. CMake compile to static . First it's important to recognize that static libraries do not link other static libraries into the code. The first thing to know: one doesn't link a static library - one uses an archiver (ar on Linux), which just puts all object files into one archive - libXXX. 12. 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. h -march=native -mno-avx512f -g CMakeFiles/dpdk_test. cpp) target_link_libraries(testlib lib1 ) LIBRARY_TYPE=STATIC.

Link order matters. You can link to these directly. This is because CMake expects a SHARED library to always have an associated import library on Windows. You can build a static library and a second one and have your executable project linked against both, but it's not possible to link the first static library with the second library and then link them into the final executable. 6. As per CMake documentation, target_link_options() is just an alternative to target_link_libraries(), it is not a recommended replacement. 2 Proper way to link static library into shared library with CMake. The best solution is to use find_package(Threads) and 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(). NOTE: Inference backends located in external repositories can also be used in a static build. How to find my generated shared library from cmake? 0. 3 The static library (A) itself links some system provided static libraries like this target_link_libraries(A PUBLIC -Wl,-Bstatic ${YAML_STATIC_LIBRARIES} ${MINIZIP_STATIC_LIBRARIES} ${PCAP_STATIC_LIBRARIES} I have a static libary mylib that depends on the math library. cpp) target_include_directories(staticLibA INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}/. I didn't get works because link_directories have to put in front of add_executable. lib files in cmake. 28. CMake: handle linking of I am trying to link to a specific QNX library for the architecture I’m cross compiling for. c) target_compile_options(unit1 PRIVATE -fPIC) add_library(unit2 OBJECT unit2. If I first link mylib with math and then to my executable it works: add_executable(myapp main. add_library(foo SHARED foo. 2. txt ├── include │ └── DepTest │ └── a. CMake: Different compile definitions for static and shared library. CMake link a shared library to static libraries. The pkg-config --static option relies on proper tagging in the . Let's ignore header files for now, as they can be all included in your source files. cmake and when it's built as a static library, we get SomeLib-static-targets. Some linkers support switches such as -Bstatic and -Bdynamic to determine whether to use static or shared libraries for -lXXX options. cpp with shared libraries and static libraries. 04, cmake 3. How to create a shared library wrapper for a static library (without using source files) with CMake? 3. 3. Errors during linking a static cURL using CMake. See the different signatures, options, and examples of the command. I have a very similar problem to one described on the cmake mailing list where we have a project dependent on many static libraries (all built from source in individual submodules, each with their own CMakeLists. If providing the --static option does not return correct information necessary to link against the libpng archive, then you cannot use pkg-config for that purpose. The latter is easy to auto-generate since we're using semantic CMake: Linking a static library from a subdirectory to an executable in another subdirectory. The "-Wl,-Bdynamic" Learn how to specify libraries or flags to use when linking a target and/or its dependents with CMake. There are several ways to do that: Using absolute path to the library file in target_link_libraries, or using IMPORTed library target with absolute path, or using 'link_directories' call with directory where to search the library. framework". c: log) # Specifies libraries CMake should link to your target library. cpp, main. 1). `target_link_libraries(C1 EXECUTABLE PUBLIC B)` (Instead of an executable exeC1 you could have created a shared library libC1 instead. cpp. Viewed 2k times 1 I'm trying to refactor some classes from a large main file into separate header and cpp files and am getting undefined reference errors at link time. The -static-libstdc++ option directs the g++ driver to link libstdc++ statically, without On 06/29/2011 02:32 PM, Michael Wild wrote: > On 06/29/2011 02:30 PM, Stephen Torri wrote: >> Normally we use target_link_libraries to link against certain libraries. Cmake: linking to static internal library without exporting it. I have a . creating an executable exeC1 using target C1 which just links (via `target_link_libraries`) to target B. g++ -O0 -g main. Note: modern CMake has a better solution than mentioned below (see updates for details). By default the library file will be At least with CLion under Windows (CLion 2016. Link with self-compiled static libraries with cmake. txt (1) | main. one ending with a . I want to link against libpng which is present in my system. But I needed to integrate one (prj1) to the other one (prj2). To control link options for normal and device link steps, $<HOST_LINK> and Instead, CMake makes sure to link both static library files libB and libA when e. cpp Somehow the answer from @Mike Willekes got CMake linking in the same target both release and debug for me :(. txt ├── build ├── lib │ ├── CMakeLists. Follow edited Nov 15, 2017 at 7:38. If a library however is marked as “build_standalone”, we only build the . Cmake link static lib against shared one.

Static linking . sa means shared archive; we have very broad platform support also). cpp | cudafunction. C++ Linking Static Library against Shared Library. A combined library must be created, which on Linux can be done with ar. Also note that target_link_options() "cannot be used to add options for static library targets, since they do not use a linker".
