Deployment under linux platform

[Abdeljalil]

I want to deploy my first software under linux platforms.
a lot of distribution does not support Qt5 yet.
so i need to include runtime libraries in my program
my question is:
where can i find shared libraries (.so) files? (libQt5Gui.so, libQt5Core.so, ... )
and should i put them in the same compiled program directory or somewhere else?

You can put the into the same directory as the executable or in any subfolder of your install path, e.g. a "lib" subdirectory.

Your application's start script then sets the $LD_LIBRARY_PATH variable such that this directory is part of the search path for libraries.

Something like

#!/bin/bash
INSTALL_FULLPATH=$(readlink -f "$0")
INSTALL_PATH=$(dirname "$INSTALL_FULLPATH")
LIB_PATH="$INSTALL_PATH"/lib
BIN_PATH="$INSTALL_PATH/bin"
 
export LD_LIBRARY_PATH="$LIB_PATH":$LD_LIBRARY_PATH
 
"$BIN_PATH"/program "$@"

#!/bin/bash
INSTALL_FULLPATH=$(readlink -f "$0")
INSTALL_PATH=$(dirname "$INSTALL_FULLPATH")
LIB_PATH="$INSTALL_PATH"/lib
BIN_PATH="$INSTALL_PATH/bin"

export LD_LIBRARY_PATH="$LIB_PATH":$LD_LIBRARY_PATH

"$BIN_PATH"/program "$@"
