I seem to have some problems including portaudio to my project, I guess my
error is caused be me not including portaudio accurately to my project.
My project source tree looks like this
audio$ tree

│ └── portaudio.h
├── record.cpp
├── record.h
├── spectogram.cpp
└── spectogram.h
7 directories, 45 files
In which I have, as suggested by the portaudio guide, copy pasted the
libportaudio.a and portaudio.h into my project folder.
My cmakelist looks like this
project(audio)
cmake_minimum_required(VERSION 2.8)
aux_source_directory(. SRC_LIST)
add_executable(${PROJECT_NAME} ${SRC_LIST})
So it should include all the files..
but defining a function as such
void record::example()
{
std::cout << "In example!" << std::endl;
std::cout << Pa_GetVersion() << std::endl;
}
Is not possible.. , I get an compile error stating that undefined reference to
Pa_GetVersion()..
As if it doesn’t know the existence of this. How do i fix that?--
