We will want to start out with the dependencies needed by Fedora 29 to successfully compile GameHub. Type or copy/paste the following into a terminal.
sudo dnf install vala-devel vala granite-devel webkit2gtk3-devel json-glib-devel sqlite-devel polkit-devel cmake ninja menson libgee-devel libsoup-devel libxml2-devel libXtst-devel libX11-develAfter the dependencies install we want to track down one more library needed to compile. This is libmanette. Manette doesn't seem to be available for Fedora 29 so I went to Fedora Rawhide to the package. Below are the steps involved in obtaining the package and installing it.
Go to https://pkgs.org/download/libmanette and click on the fedora link. You will want to download the libmanette-0.2.2-1.fc30.x86_64.rpm. Next use the following rpm command to install the package. Double clicking and installing the rpm via Gnome's Software application will not work.
sudo rpm -Uvh libmanette-0.2.2-1.fc30.x86_64.rpmOnce Manette is installed we will begin the compile process. Use the below commands to obtain the GameHub source and compile the code. Each line is a separate command.
git clone https://github.com/tkashkin/GameHub.git
meson build --prefix=/usr -Ddistro=generic --buildtype=debug
sudo ninja install
