Now that you have done that let us check out how to use the particular command to uninstall software on your Ubuntu OS run the dpkg command to view installed files 1.a) Using the apt-get remove command to uninstall software Note: If you intend to copy the exact package name, you must select and highlight it, right-click, and copy it for future use. The following code will list all of the packages that are currently installed on your system: dpkg -list But first, you must know the exact package name under which the software was installed. You can delete installed applications from your system using the sudo commands apt-get remove and apt-get purge. Sit tight since we shall be illustrating all the different ways a terminal can be used to uninstall unwanted software from your Ubuntu workstation. This method contains different ways that can be used to uninstall or remove the software from Ubuntu. Method 1: Uninstalling software using the terminal Uninstalling software using the Ubuntu Software Center (GUI method).Uninstalling software using the terminal.The primary methods we shall look at in this article are: These packages are compatible with all Linux distributions. Snap and Flatpak packages were introduced to accommodate alternative distributions. These packages are available solely for Debian-based distributions such as Ubuntu. On Windows, you must set LLVM_INSTALL_DIR to the installation path.ĮRROR: Feature 'dbus-linked' was enabled, but the pre-condition 'features.dbus & libs.dbus' failed.ĮRROR: Feature 'openssl-linked' was enabled, but the pre-condition '!curetransport & !features.schannel & libs.openssl' failed.ĮRROR: Feature 'xcb' was enabled, but the pre-condition 'features.thread & features.xkbcommon & libs.xcb' failed.ĮRROR: Feature 'fontconfig' was enabled, but the pre-condition '!config.msvc & features.system-freetype & libs.fontconfig' failed.Native packages, often known as Debian packages, are packages that may be discovered in and uploaded to Ubuntu’s repository. On macOS, you can use Homebrew's llvm package. On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution. This means that you cannot build the Qt documentation.Įither ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation. WARNING: QDoc will not be compiled, probably because libclang could not be located. Or compile needed modules into the library. Make sure to import all needed static plugins, Note: Using static linking will disable the use of dynamically Note: Also available for Linux: linux-clang linux-icc Note: Overriding option 'freetype' with 'yes' (was: 'qt') So read here to learn more about static build and their information for you to understand it.Ĭd ~/QtStatic/5.14.0/build ~/QtStatic/5.14.0/Src/configure -v -static -release -ltcg -optimize-size -no-pch -prefix ~/Qt5static/5.14.0/ -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -qt-xcb -qt-harfbuzz -make libs -nomake tools -nomake examples -nomake tests -opensource -confirm-license -skip qtwebengine -dbus-linked -no-rpath -openssl-linked -opengl desktop -sysconfdir "/etc/xdg" -no-qml-debug -feature-freetype -fontconfig -feature-relocatable -strip So you need to learn how to ship your full app with all its dependencies :) Other way to send it one file is to use static build which will compile and ship all requirements in one binary file. Which you have to ship them all together with your app. How to know which dependencies i need to run my app: If I try to run in the folder generated it will not run if the generated app can not find the dependencies in your machine or other machines , because QtCreator loads the dependencies. If i run it in QtCreator it will run without any issue. So let say I Build My app called FoxApp using QtCreator. And that is what they call it Dependency. If you try to run the app in another machine It will not run unless you have the same Qt and system lib version installed in that machine. means it depends on other Qt and System libraries you used to compile or generate the app in your machine. It builds the app as a shared application. You have Qt framework in your machine you use to build the app.
