我已经尝试了一段时间，将portaudio包含到我的c++项目中，但是似乎存在一些问题，因为我的项目不“知道” portaudio命名空间，而是qt自动完成函数名称，就好像它知道它们一样。

portaudio教程建议在Linux环境中构建portaudio，需要从portaudio源文件中复制当前驻留在audio / portaudio中的文件，这显然足够了。

我尝试将portaudio包含到我的记录类中，然后查看它是否了解portaudio函数(例如Pa_getversion ..)，但相反，我似乎得到了以下错误消息:

最佳答案
QtCreator确实会调查您的文件系统。因此，它将查找不在CMakeLists.txt范围内的文件。据我所知，这也适用于自动补全。
在我们的CMakeLists.txt中，没有一行可将静态库添加到您的项目中。就像是
add_library(libaudio NAME libportaudio.a PATHS ${CMAKE_CURRENT_SOURCE_DIR}/portaudio)
...
add_executable(${PROJECT_NAME} ${SRC_LIST})
target_link_libraries(${PROJECT_NAME} ${libaudio})
似乎丢失了。
尝试将libportaudio构建为共享库。阅读构建说明或调用portaudio的
./configure --help以获取更多详细信息。关于c++ - PaError不是类或 namespace ，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/46886033/
