如何静态链接portaudio？

Question

我想用portaudio库编写一些程序。我下载了源代码，打开了cmake项目并构建了静态（libportaudio_static.a）和动态（libportaudio.dll和libportaudio.dll.a）文件。

然后，我创建了只有主文件的C++项目，我试图打印出portaudio库的版本。当我使用动态链接时，它工作，但我似乎无法使用静态链接。它给了我未定义的参考Pa_GetVersion()方法。

我在做什么错？

我使用Clion并用CMake构建它。我有Windows 10

这是我的CMakeLists.txt：

cmake_minimum_required(VERSION 3.6) 
project(snoozeRec) 

set(CMAKE_CXX_STANDARD 11) 

set(SOURCE_FILES main.cpp) 
# first way i tried to use static library 
#set(CMAKE_EXE_LINKER_FLAGS ${CMAKE_EXE_LINKER_FLAGS} "-Lportaudio_static") 

add_executable(
    snoozeRec 
    ${SOURCE_FILES} 
    #portaudio.h 
    # second way i tried to use static library 
    #${PROJECT_SOURCE_DIR}/libportaudio_static.a 
) 

target_link_libraries(snoozeRec ${CMAKE_SOURCE_DIR}/libportaudio.dll) 

这是我的main.cpp：

#include <iostream> 

#include "portaudio.h" 

int main() 
{ 
    std::cout << "Version of portAudio: " << Pa_GetVersion() << std::endl; 
    return 0; 
} 

为了简单起见，我把所有的文件中相同的目录。

试图在add_executable使用${PROJECT_SOURCE_DIR}/libportaudio_static.a，或set(CMAKE_EXE_LINKER_FLAGS ${CMAKE_EXE_LINKER_FLAGS} "-Lportaudio_static") 给了我这个错误：

C：/Users/duso/ClionProjects/snoozeRec/main.cpp：7：未定义的引用`Pa_GetVersion”

如果我尝试@亚历克斯zywicki的建议，使用target_link_libraries(snoozeRec ${CMAKE_SOURCE_DIR}/libportaudio_static.a)，它给了我未定义的引用一堆：

Answer 1

所以，我设法解决这个问题。我问过我在学校的主管，他建议我将整个portaudio资源添加到我的项目中，并将其cmakelists添加到我的项目中。生成的CMakeLists.txt看起来像这样：

cmake_minimum_required(VERSION 3.6) 
project(snoozeRec) 

set(CMAKE_CXX_STANDARD 11) 

add_subdirectory("C:\\portaudio" asdf) 

add_executable(
     snoozeRec 
     main.cpp 
) 

target_link_libraries(snoozeRec portaudio_static) 

Answer 2

您是否尝试过更换：

target_link_libraries(snoozeRec${CMAKE_SOURCE_DIR}/libportaudio.dll) 

有了：

target_link_libraries(snoozeRec${CMAKE_SOURCE_DIR}/libportaudio_static.a)
