Installation guide

Intel® Parallel Studio XE 2015 Composer Edition for C++ Linux*
Installation Guide and Release Notes 14
 uninstall – Files for uninstallation
If you have both the Intel C++ and Intel Fortran compilers installed, they will share folders for a
given version and update.
This directory layout allows you to choose whether you want the latest compiler, no matter
which version, the latest update of the Intel® Parallel Studio XE 2015 compiler, or a specific
update. Most users will reference <install-dir>/bin for the compilervars.sh [.csh]
script, which will always get the latest compiler installed.
2.11 Removal/Uninstall
Removing (uninstalling) the product should be done by the same user who installed it (root or a
non-root user). If sudo was used to install, it must be used to uninstall as well. It is not possible
to remove the compiler while leaving any of the performance library or Eclipse* integration
components installed.
1. Open a terminal window and set default (cd) to any folder outside <install-dir>
2. Type the command: <install-
dir>/composer_xe_2015.<n>.<pkg>/uninstall.sh for a command-line uninstall
or <install-dir>/composer_xe_2015.<n>.<pkg>/uninstall-GUI.sh for a
GUI uninstall.
3. Follow the prompts
4. Repeat steps 2 and 3 to remove additional platforms or versions
If you have the same-numbered version of Intel® Fortran Compiler installed, it may also be
removed.
If you have added the Intel C++ Eclipse integration to an instance of Eclipse in your
environment, you will need to update your Eclipse configuration by removing the Intel integration
extension site from your Eclipse configuration. To do this, Go to Help > About Eclipse and click
on "Installation Details". Select "Intel(R) C++ Compiler XE 15.0 for Linux* OS " under "Installed
Software" and click on "Uninstall..." Click "Finish". When asked to restart Eclipse, select "Yes".
