作業系統：
Qt程式碼：
用Release模式Build原始碼：
試著執行編譯好的Qt程式碼：
找到Release Build的資料夾位置：
Step 1 . Set up the deployment directory
Step 2. Go to linuxdeployqt github
Step 3. Download the latest release of linuxdeployqt from github
The first option to download the release,
The second option to download the release:
Download the .AppImage
Executing the .AppImage file provides you with hints about how to use it

linuxdeployqt 4 (commit 8b3ded6), build 571 built on 2018-10-07 20:58:12 UTC
Usage: linuxdeployqt <app-binary|desktop file> [options]
Options:
-always-overwrite : Copy files even if the target file exists.
-appimage : Create an AppImage (implies -bundle-non-qt-libs).
-bundle-non-qt-libs : Also bundle non-core, non-Qt libraries.
-exclude-libs=<list> : List of libraries which should be excluded,
separated by comma.
-ignore-glob=<glob> : Glob pattern relative to appdir to ignore when
searching for libraries.
-executable=<path> : Let the given executable use the deployed libraries
too
-extra-plugins=<list> : List of extra plugins which should be deployed,
separated by comma.
-no-copy-copyright-files : Skip deployment of copyright files.
-no-plugins : Skip plugin deployment.
-no-strip : Don't run 'strip' on the binaries.
-no-translations : Skip deployment of translations.
-qmake=<path> : The qmake executable to use.
-qmldir=<path> : Scan for QML imports in the given path.
-qmlimport=<path> : Add the given path to QML module search locations.
-show-exclude-libs : Print exclude libraries list.
-verbose=<0-3> : 0 = no output, 1 = error/warning (default),
2 = normal, 3 = debug.
-version : Print version statement and exit.
linuxdeployqt takes an application as input and makes it
self-contained by copying in the Qt libraries and plugins that
the application uses.
By default it deploys the Qt instance that qmake on the $PATH points to.
The '-qmake' option can be used to point to the qmake executable
to be used instead.
Plugins related to a Qt library are copied in with the library.
See the "Deploying Applications on Linux" topic in the
documentation for more information about deployment on Linux.
Here are the specifications for writing .desktop files: specifications.freedesktop.org/des...
This is an example of a .desktop file

ERROR: qmake not found on the $PATHSolution: Add qmake path to the environment $PATH variable
Delete the files already generated
Run the terminal command to add its path to the $PATH environment variable
Get the directory path towards the ‘bin’ directory:
georgeca@georgeca-VirtualBox:~/Qt/5.14.2/gcc_64$ cd bin/
georgeca@georgeca-VirtualBox:~/Qt/5.14.2/gcc_64/bin$ pwd
/home/georgeca/Qt/5.14.2/gcc_64/binAdd to the $PATH variable
georgeca@georgeca-VirtualBox:~/Qt/5.14.2/gcc_64/bin$ export PATH=/home/georgeca/Qt/5.14.2/gcc_64/bin/:$PATHAfter adding the qmake path, the environment variable $PATH is going to look like this:
OPTION 1: Run linuxdeployqt to deploy the necessary Qt libraries inside the deployment directory
The outcome is:
The directories in the deployment contain all the necessary Qt libraries to run the application:
