+# Quick and dirty guide for compiling remmina on ubuntu 18.04
+
+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](https://gitlab.com/Remmina/Remmina/wikis/home).
+
+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:
+
+```shell
+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.
+
+```shell
+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
+
+```shell
+mkdir ~/remmina_devel
+cd ~/remmina_devel
+```
+
+**4.** Download the latest source code of FreeRDP from its master branch
+
+```shell
+git clone https://github.com/FreeRDP/FreeRDP.git
+cd FreeRDP
+```
+
+**5.** Configure FreeRDP for compilation (don't forget to include -DWITH_PULSE=ON)
+
+```shell
+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
+
+```shell
+make && sudo make install
+```
+
+**7.** Make your system dynamic loader aware of the new libraries you installed. For Ubuntu x64:
+
+```shell
+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
+
+```shell
+sudo ln -s /opt/remmina_devel/freerdp/bin/xfreerdp /usr/local/bin/
+```
+
+**9.** Test the new freerdp by connecting to a RDP host
+
+```shell
+xfreerdp +clipboard /sound:rate:44100,channel:2 /v:hostname /u:username
+```
+
+**10.** Now clone remmina repository to your devel dir:
+
+```shell
+cd ~/remmina_devel
+git clone https://gitlab.com/Remmina/Remmina.git
+```
+
+**11.** Configure Remmina for compilation
+
+```shell
+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
+
+```shell
+make && sudo make install
+```
+
+**13.** Create a symbolik link to the the executable
+
+```shell
+sudo ln -s /opt/remmina_devel/remmina/bin/remmina /usr/local/bin/
+```
+
+**14.** Run remmina
+
+```shell
+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
+
+```shell
+rm -rf ~/remmina_devel/
+```
+
+**2.** Remove the binary directory
+
+```shell
+sudo rm -rf /opt/remmina_devel/
+```
+
+**3.** Cleanup symlinks and dynamic loader
+
+```shell
+sudo rm /etc/ld.so.conf.d/freerdp_devel.conf /usr/local/bin/remmina /usr/local/bin/xfreerdp
+sudo ldconfig
+```
