如何包含PulseAudio核心接头？

Question

I am writing a program which should get sound from a pulseaudio source. I took pacat.c source file as an example.

Some of functions are declared in /pulsecore/*.h I include them into my source code:

#include <pulsecore/log.h>

#include <pulsecore/core-error.h>

#include <pulsecore/macro.h>

#include <pulsecore/g711.h>

#include <pulsecore/core-util.h>

But compiler can't find them. fatal error: pulsecore/log.h: No such file or directory

I build pulseaudio 9.0 with Yocto.

In /$BUILDSDIR/pulseaudio/9.0-r0/image there are no such headers. But they exist in pulseaudio source code and also there /pulseaudio/9.0-r0/package/usr/src/debug/pulseaudio/9.0-r0/pulseaudio-9.0/src/pulsecore/

Is there any special option for pulseaduio to configure to copy headers into image? Or I should update yocto recipe to copy desired files?

Answer 1

If you check the $WORKDIR of pulseaudio you will find the folder packages-split containing each package and its content.

I am not sure whether what you try is possible, but the files you are trying to use are provided in the package pulseaudio-dbg . Which you could try yo install either via image recipe or in your local.conf. (IMAGE_INSTALL or CORE_IMAGE_EXTRA_INSTALL variables respectively)

You can find the package itself in $WORKDIR/deploy-[rpm|ipk|deb]/
