Quick and dirty guide for compiling remmina on ubuntu 20.04

These are instructions for people or software developers who want to contribute to the latest version of Remmina on Ubuntu 20.04.

If you are an end user and you want to install the latest version of remmina, please use the "Remmina Team Ubuntu PPA - next branch", as explained on the homepage of the wiki.

By following these instructions, you will get Remmina and FreeRDP compiled under the /opt/remmina_devel/ subdir, so they will not mess up your system too much. This is ideal for testing remmina.

You will also find the uninstall instructions at the bottom of this page.

1. Install all packages required to build freerdp and remmina:

sudo apt install build-essential git-core cmake libssl-dev libx11-dev libxext-dev libxinerama-dev 
  libxcursor-dev libxdamage-dev libxv-dev libxkbfile-dev libasound2-dev libcups2-dev libxml2 libxml2-dev 
  libxrandr-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev 
  libxi-dev libavutil-dev 
  libavcodec-dev libxtst-dev libgtk-3-dev libgcrypt20-dev libssh-dev libpulse-dev 
  libvte-2.91-dev libxkbfile-dev libtelepathy-glib-dev libjpeg-dev 
  libgnutls28-dev libavahi-ui-gtk3-dev libvncserver-dev 
  libappindicator3-dev intltool libsecret-1-dev libwebkit2gtk-4.0-dev libsystemd-dev 
  libsoup2.4-dev libjson-glib-dev libavresample-dev libsodium-dev 
  libusb-1.0-0-dev

2. Remove freerdp-x11 package and all packages containing the string remmina in the package name.

sudo apt purge "?name(^remmina.*)" "?name(^libfreerdp.*)" "?name(^freerdp.*)" "?name(^libwinpr.*)"

3. Create a new directory for development in your home directory, and cd into it

mkdir ~/remmina_devel
cd ~/remmina_devel

4. Download the latest source code of FreeRDP from its master branch

git clone --branch stable-2.0 https://github.com/FreeRDP/FreeRDP.git
cd FreeRDP

5. Configure FreeRDP for compilation (don't forget to include -DWITH_PULSE=ON)

cmake -DCMAKE_BUILD_TYPE=Debug -DWITH_SSE2=ON -DWITH_CUPS=on -DWITH_PULSE=on -DCMAKE_INSTALL_PREFIX:PATH=/opt/remmina_devel/freerdp .

Please note that the above line will make FreeRDP install in /opt/remmina_devel/freerdp

6. Compile FreeRDP and install

make && sudo make install

7. Make your system dynamic loader aware of the new libraries you installed. For Ubuntu x64:

echo /opt/remmina_devel/freerdp/lib | sudo tee /etc/ld.so.conf.d/freerdp_devel.conf > /dev/null
sudo ldconfig

8. Create a symbolik link to the executable in /usr/local/bin

sudo ln -s /opt/remmina_devel/freerdp/bin/xfreerdp /usr/local/bin/

9. Test the new freerdp by connecting to a RDP host

xfreerdp +clipboard /sound:rate:44100,channel:2 /v:hostname /u:username

10. Now clone remmina repository to your devel dir:

cd ~/remmina_devel
git clone https://gitlab.com/Remmina/Remmina.git

11. Configure Remmina for compilation

cd Remmina
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX:PATH=/opt/remmina_devel/remmina -DCMAKE_PREFIX_PATH=/opt/remmina_devel/freerdp --build=build .

12. Compile remmina and install it

make && sudo make install

13. Create a symbolik link to the the executable

sudo ln -s /opt/remmina_devel/remmina/bin/remmina /usr/local/bin/

14. Run remmina

remmina

Please note that icons and launcher files are not installed, so don't search for remmina using Unity Dash.

Uninstall everything

1. Remove the devel directory

rm -rf ~/remmina_devel/

2. Remove the binary directory

sudo rm -rf /opt/remmina_devel/

3. Cleanup symlinks and dynamic loader

sudo rm /etc/ld.so.conf.d/freerdp_devel.conf /usr/local/bin/remmina /usr/local/bin/xfreerdp
sudo ldconfig
