Question

我正在尝试编写PulseAudio模块。首先，我为this文档中提到的模块编写了以下最小代码。

#include <pulsecore/module.h>
int pa__init(pa_module *m)
{
    return 0;
}

我尝试使用以下命令对其进行编译：

gcc -g -shared -o module-test.so module-test.c

但是它给出了错误：

 pulsecore/module.h: No such file or directory
 #include <pulsecore/module.h>
          ^~~~~~~~~~~~~~~~~~~~
 compilation terminated.

在Internet上搜索后，我发现必须安装libpulse-dev，但是已经安装了pulseaudio和libpulse-dev，如下所示。

jyotesh@jyotesh-VM:~$ sudo apt install pulseaudio libpulse-dev
[sudo] password for jyotesh:

libpulse-dev is already the newest version (1:11.1-1ubuntu7.2).
pulseaudio is already the newest version (1:11.1-1ubuntu7.2).
0 upgraded, 0 newly installed, 0 to remove and 10 not upgraded.

我尝试使用locate，find，apt-file等搜索头文件。找不到该头文件的位置。

有人知道如何编译PulseAudio模块吗？

通过遵循here和here的步骤，我能够编译代码并构建module-test.so文件。我将在这里重复步骤：

首先，我从源代码构建并安装了PulseAudio v12.2。

# Clone PulseAudio git repository
git clone https://gitlab.freedesktop.org/pulseaudio/pulseaudio.git

# I wanted 12.2 version of PulseAudio, so I checked out that version
cd pulseaudio
git checkout tags/v12.2

# Install the dependencies
sudo apt-get -y build-dep pulseaudio

# Build PulseAudio source code
./bootstrap.sh
make

# Install and configure dynamic linker run-time bindings (so that
# ld can find the libraries that you specify while building your module)
sudo make install
sudo ldconfig

此后，我为模块编写了最少的代码。

#include <config.h> // this is required, otherwise you will get compilation errors
#include <pulsecore/module.h>
int pa__init(pa_module *m)
{
    return 0;
}

要编译此文件，我使用了命令

gcc -g -shared -fPIC -I/home/jyotesh/pulseaudio -I/home/jyotesh/pulseaudio/src -L/home/jyotesh/pulseaudio/.libs -L/usr/local/lib/pulseaudio -o module-test.so module-test.c -lpulsecore-12.2 -lpulsecommon-12.2 -lpulse

如何编译自定义PulseAudio模块？
