Currently there is no official rpm pacakge available for the GUI version of the Seafile 3 client. You can find extensive build instructions here:

Build and Use Seafile client from Source

I had to add the Vala package to the dependencies:

sudo yum install vala vala-compat wget gcc libevent-devel openssl-devel gtk2-devel libuuid-devel sqlite-devel jansson-devel intltool cmake qt-devel fuse-devel

Current versions:

Here’s a little fix up for the script parts:

#!/usr/bin/env bash

echo "Building and installing seafile client"

export version=3.0.2 # change this to your preferred version
alias wget='wget --content-disposition -nc'
wget https://github.com/haiwen/libsearpc/archive/v${version}.tar.gz
wget https://github.com/haiwen/ccnet/archive/v${version}.tar.gz
wget https://github.com/haiwen/seafile/archive/v${version}.tar.gz
wget https://github.com/haiwen/seafile-client/archive/v${version}.tar.gz
tar xf libsearpc-${version}.tar.gz
tar xf ccnet-${version}.tar.gz
tar xf seafile-${version}.tar.gz
tar xf seafile-client-${version}.tar.gz

export PREFIX=/usr
export PKG_CONFIG_PATH="$PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH"
export PATH="$PREFIX/bin:$PATH"

echo "Building and installing libsearpc"

cd libsearpc-${version}
./autogen.sh
./configure --prefix=$PREFIX
make
sudo make install

cd ..

echo "Building and installing ccnet"

cd ccnet-${version}
./autogen.sh
./configure --prefix=$PREFIX
make
sudo make install

cd ..

echo "Building and installing seafile"

cd seafile-${version}/
./autogen.sh
./configure --prefix=$PREFIX --disable-gui
make
sudo make install

cd ..

echo "Building and installing seafile-client

cd seafile-client-${version}
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$PREFIX .
make
sudo make install

Run the lib linker, just in case sudo ldconfig

Start the client with seafile-applet
