Compilation guide for CentOS 7

These are the instructions for people who want to test the latest version of Remmina (master branch) on CentOS 7.

This guide was tested on CentOS 7 GNOME Desktop without any other package/group.

If you want to uninstall the program, follow the instructions in the step 0.

0. It is important that no other remmina or freerdp version is installed, therefore we need to remove it. ``bash <h1>To check if a program is installed, we can usewhereis [program(s)]` whereis freerdp remmina

When freerdp is installed from the CentOS repo, use this command to remove it

sudo yum -y remove freerdp*

When freerdp is installed from source code, enter the freerdp source code folder and run the following command

cd ${HOME}/git/freerdp sudo rm $(cat install_manifest.txt)

When remmina is installed from the CentOS repo, use this command to remove it

sudo yum -y remove remmina*

When remmina is installed from source code, enter the build folder in remmina source code folder and run the following command

cd ${HOME}/git/remmina/build sudo make uninstall

Finally, we need to delete the empty folders of remmina and freerdp

This needs to be run for uninstallation of either programs

sudo rmdir $(find $(whereis freerdp remmina | grep -Po "^[^:]*: \K.*$") -type d | tac) ```

1. Add necessary repos. Note that on CentOS 7 GNOME Desktop only epel and rpmfusion-free-updates are not installed by default. I presume that base, extras and updates repos are installed on all version of CentOS 7. ``bash <h1>epel: required foropenjpeg2-devel,openssl-devel` sudo yum -y install epel-release

rpmfusion-free-updates: required for ffmpeg-devel

sudo yum -y install https://download1.rpmfusion.org/free/el/rpmfusion-free-release-$(rpm -E centos).noarch.rpm

**3.** Update your system and `yum` cache. This might require a reboot.
```bash
sudo yum -y update

4. Install dependencies of freerdp and remmina.

sudo yum -y install alsa-lib-devel avahi-ui-devel avahi-ui-gtk3 cmake cmake3 cups-devel \
ffmpeg-devel gcc gcc-c++ git glib2-devel gnutls-devel gstreamer1-devel \
gstreamer1-plugins-base-devel gtk3-devel json-glib-devel libappindicator-devel \
libappindicator-gtk3 libappindicator-gtk3-devel libgcrypt-devel libgnome-keyring-devel \
libSM-devel libsodium libsodium-devel libsoup-devel libssh-devel libvncserver-devel libX11-devel \
libXcursor-devel libXdamage-devel libXext-devel libXi-devel libXinerama-devel libxkbfile-devel \
libXrandr-devel libXtst-devel libXv-devel openjpeg2-devel openssl-devel pulseaudio-libs-devel \
telepathy-glib-devel vte3-devel webkitgtk4-devel xmlto

5. Clone FreeRDP and Remmina repos. You may want to modify the ${HOME}/git/{freerdp,remmina} paths and the folder names.

mkdir -p ${HOME}/git/{freerdp,remmina}
cd ${HOME}/git
git clone https://github.com/FreeRDP/FreeRDP.git freerdp
git clone https://gitlab.com/Remmina/Remmina.git remmina

6. Build FreeRDP.

cd freerdp
mkdir build
cd build
# In the following line, the `DWITH_PULSE=ON` need to be included
cmake -DCMAKE_BUILD_TYPE=Debug -DWITH_SSE2=ON -DWITH_PULSE=ON -DWITH_CUPS=on -DWITH_WAYLAND=off -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
make && sudo make install

7. Make your system dynamic loader aware of the new libraries you installed

sudo ldconfig

8. Build Remmina.

mkdir ../../remmina/build
cd ../../remmina/build
# cd ../../remmina
# git checkout v1.3.4
# mkdir build
# cd build
cmake3 -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX:PATH=/usr -DCMAKE_PREFIX_PATH=/usr --build=build ..
make && sudo make install

9. Now you should be able to run Remmina with the following command or using the GUI.

remmina &> /dev/null &

NOTES for execution:

• Current GNOME Shell versions does not include system tray, therefore vanilla GNOME will not show the Remmina system tray icon and menu. Press Super+M to see the Remmina icon on the message bar. If you want to fix this, you could install either AppIndicator Support or TopIcons Plus.
• [This might be outdated] XFCE and other desktop environments without app indicator support, will not show you the system tray icon if you are executing Remmina from its compilation folder (e.g. ~/git/remmina) because it contains a folder named remmina. See Bug #1363277 on Launchpad
