Question

使用CMake构建一个开源项目时（在我的例子中，它是柠檬图库），当我尝试通过-DBUILD_SHARED_LIBS=1构建共享库时出现此错误：

TARGETS given no LIBRARY DESTINATION for shared library target

此错误来自何处以及如何解决？

Answer 1

在我的CMakeLists.txt中，我的INSTALL命令没有LIBRARY参数。

从此改变：

INSTALL(
  TARGETS lemon
  ARCHIVE DESTINATION lib
  COMPONENT library
)

到此：

INSTALL(
  TARGETS lemon
  ARCHIVE DESTINATION lib
  LIBRARY DESTINATION lib  # <-- Add this line
  COMPONENT library
)

解决了我的问题。

Answer 2

我明白了......发生这种情况的另一个原因是你创建了一个共享库

add_library（$ {NAME} SHARED来源）

然后当Cmake在Windows平台上达到安装命令时，它会抱怨这些错误，解决方法是使用RUNTIME而不是LIBRARY，比如

if(WIN32)
  install(TARGETS ${NAME}
    RUNTIME DESTINATION path)
else()
  install(TARGETS ${NAME}
    LIBRARY DESTINATION path)
endif()

Answer 3

在struct Dummy { int a; double b; }; extern "C" void SetArray(Dummy* x, int cnt); extern "C" void SetArray(Dummy x, int cnt) { // a TODO placeholder. }之后，它应该具有DESTINATION，bin，lib。

安装include或lib

bin

例如，安装install(TARGETS snappy EXPORT SnappyTargets # RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR} # DESTINATION error RUNTIME DESTINATION bin ${CMAKE_INSTALL_BINDIR} # should add bin or other dir LIBRARY DESTINATION lib ${CMAKE_INSTALL_LIBDIR} # ARCHIVE DESTINATION ${CMAKE_INSTALL_LIBDIR # DESTINATION error ARCHIVE DESTINATION lib ${CMAKE_INSTALL_LIBDIR} # should add lib )文件：

.h

有关更多详细信息，请参见https://cmake.org/cmake/help/v3.0/command/install.html

install(
        FILES
        "${PROJECT_SOURCE_DIR}/test_hard1.h"
        "${PROJECT_BINARY_DIR}/config.h"
        # DESTINATION ${CMAKE_INSTALL_INCLUDEDIR} #  error install FILES given no DESTINATION!

        # add include after DESTINATION, then it works
        DESTINATION include ${CMAKE_INSTALL_INCLUDEDIR}
)

Answer 4

我刚刚遇到了类似的问题。正如@Fernando在他的回答中所说，您可以采用该解决方案。另一个类似的解决方案是仅include(GNUInstallDirs)

include(GNUInstallDirs)
install(TARGETS ${PROJECT_NAME}
    EXPORT "${PROJECT_NAME}Config"
    ARCHIVE DESTINATION ${CMAKE_INSTALL_LIBDIR}
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)

CMake错误：TARGETS没有为共享库目标提供LIBRARY DESTINATION
