使用带有 cmake 的 libpam0g-dev 构建应用程序
Build Application using libpam0g-dev with cmake
我正在尝试构建一个使用库 libpamg0-dev 的 C++ 应用程序。
我在我的 elementaryOS VM 上使用以下命令安装了它。
apt-get install libpam0g-dev
当我尝试编译应用程序时,编译器出现以下错误:
undefined reference to `pam_start`
undefined reference to `pam_authenticate`
undefined reference to `pam_end`
我的 CMakeLists.txt 看起来像这样:
cmake_minimum_required(VERSION 3.10)
project(application)
set(CMAKE_CXX_STANDARD 11)
INCLUDE_DIRECTORIES(/home/dnagl/dev/libs/restbed/distribution/include /usr/include/security)
LINK_DIRECTORIES(/home/dnagl/dev/libs/restbed/distribution/library /usr/lib/x86_64-linux-gnu)
add_executable(application main.cpp Utils/Json/Json.cpp Utils/Json/Json.h Utils/Stringhelper/Stringhelper.cpp Utils/Stringhelper/Stringhelper.h Utils/File/Filehelper.cpp Utils/File/Filehelper.h Utils/System/SystemHelper.cpp Utils/System/SystemHelper.h Controller/Info/InfoController.cpp Controller/Info/InfoController.h Rest/ResourceHandler/ResourceHandler.cpp Rest/ResourceHandler/ResourceHandler.h Controller/System/SystemController.cpp Controller/System/SystemController.h Rest/Log/RequestLogger.cpp Rest/Log/RequestLogger.h Controller/Authentication/AuthenticationController.cpp Controller/Authentication/AuthenticationController.h Controller/Log/LogController.cpp Controller/Log/LogController.h)
target_link_libraries(application restbed)
也许你们中有人知道如何以正确的方式 link 图书馆。
我从 CMake
的 find_package
选项中找到了一个很好的解决方案。 CMake
提供了一种使用指定的 FindModule.cmake
文件查找 packages/libraries 的方法。
一个真正的好消息是有很多现有的模块文件。您可以使用 this version 在 Linux 上查找 PAM 包。将其放入项目文件夹中的 cmake/modules/
并更新 CMakeLists.txt
:
cmake_minimum_required(VERSION 3.10)
project(restbed)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)
# Notify CMake that we have module files to find packages/libs.
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/modules/")
find_package(PAM REQUIRED)
# Check if we found PAM.
if (NOT PAM_FOUND)
message(FATAL_ERROR "PAM library was not found.")
endif ()
# Source configuration.
include_directories(
${PAM_INCLUDE_DIR}
${CMAKE_BINARY_DIR}
${CMAKE_CURRENT_BINARY_DIR}
)
set(EXECUTABLE_NAME "application")
# Add sources to this project's executable.
add_executable(${EXECUTABLE_NAME}
