Question

我试图用PulseAudio lib编写一个简单的程序。当它在gcc（gcc -o name_one name_two.cpp -lpulse-simple -lpulse）下编译时，一切都很好，但当我将我的程序复制到cLion（在cmake下）时，它会抛出一个错误：

main.cpp:49: undefined reference to pa_simple_new
main.cpp:50: undefined reference to pa_strerror
main.cpp:78: undefined reference to pa_simple_drain
main.cpp:72: undefined reference to pa_simple_write
main.cpp:73: undefined reference to pa_strerror
main.cpp:79: undefined reference to pa_strerror
main.cpp:85: undefined reference to pa_simple_free

我试图将链接（-lpulse-simple -lpulse）添加到我的makeafile.txt中，如下所示：

add_compile_options(-lpulse-simple -lpulse)

但这不起作用。

怎么做得好？

添加

后

target_link_libraries("project name" pulse-simple pulse)

到我的代码，它仍然出现错误（未找到库）。我在github上找到了这句话：

find_path(PULSEAUDIO_INCLUDE_DIR
        NAMES pulse/pulseaudio.h
        DOC "The PulseAudio include directory"
        )

find_library(PULSEAUDIO_LIBRARY
        NAMES pulse
        DOC "The PulseAudio library"
        )

我将它们添加到文件中。一切正常，我的cmake文件的副本：

cmake_minimum_required(VERSION 3.8)
project(Audio)
set(CMAKE_CXX_STANDARD 11)
find_path(PULSEAUDIO_INCLUDE_DIR
        NAMES pulse/pulseaudio.h
        DOC "The PulseAudio include directory"
        )
find_library(PULSEAUDIO_LIBRARY
        NAMES pulse
        DOC "The PulseAudio library"
        )
include_directories(${PULSEAUDIO_INCLUDE_DIRS})
set(SOURCE_FILES main.cpp)
add_executable(Audio ${SOURCE_FILES})
target_link_libraries(Audio pulse-simple pulse)

PulseAudio不会在cmake上编译
