7.5 or later requires this build procedure

Prerequisites

Some build tools and package development tools are required. Make sure install the tools.

yum groupinstall "Development Tools"
yum install rpmdevtools yum-utils
rpmdev-setuptree

Prepare & build

Install pulseaudio and requisite packages to build pulseaudio.

sudo yum install pulseaudio pulseaudio-libs pulseaudio-libs-devel
sudo yum-builddep pulseaudio

Fetch the pulseaudio source and extract. You'll see `~/rpmbuild/BUILD/

yumdownloader --source pulseaudio
rpm --install pulseaudio*.src.rpm

Build the pulseaudio source. In this phase, pulseaudio is not necessarily needed to be built but configured however there's no way to do only configure.

rpmbuild -bb --noclean ~/rpmbuild/SPECS/pulseaudio.spec

Finally, let's build xrdp source / sink modules. You'll have two .so files module-xrdp-sink.so and module-xrdp-source.so.

git clone https://github.com/neutrinolabs/pulseaudio-module-xrdp.git
cd pulseaudio-module-xrdp
./bootstrap && ./configure PULSE_DIR=~/rpmbuild/BUILD/pulseaudio-10.0
make
