JDK – Java Development Kit is required by CLion. Download an archive with JDK “Linux ARM 32 Soft Float ABI” (requires to tick the radio-button regarding accepting of User Agreement).
Usually web-browsed downloads files in the folder ~/Downloads
If the downloaded JDK does not exists in it – try to find it with browser’s button “Downloads” or with the command find (with option “/” – to start from the root directory)
sudo find / -name jdk*.tar.gz
In this example archive with JDK was downloaded to the tmp folder in the root directory.
Extract the archive with JDK to folder /opt. Instead of highlighted folder and file name – use the correct name of the downloaded file. Extract the archive with the command sudo also sets root as an owner of extracted data
sudo tar -xzf ~/Downloads/jdk-8u77-linux-arm32-vfp-hflt.tar.gz -C /opt
Find the extracted folder name with JDK
Rename the extracted folder with JDK to “java”
sudo mv /opt/jdk1.8.0_77/ /opt/java
Set the environment variable pointing to the java and make it available for next sessions of bash
export JAVA_HOME=/opt/java/ echo 'export JAVA_HOME=/opt/java/' >> ~/.bashrc
Restart the terminal and verify the JAVA_HOME still available
Download archive with CLion and find downloaded file. “i” in the option -iname is to ignore case in names – the downloaded file has capital letters in its name
sudo find / -iname clion*.tar.gz
Notice the path “/home/user1/Download” is equal to the “~/Downloads” as “/home/user1” is a “home” folder for the user user1 and symbol ~ is its short writing.
Extract the file to the folder /opt
sudo tar -xzf ~/Downloads/CLion-2016.1.tar.gz -C /opt
Verify the folder with CLIon exists in the /opt folder
Rename the folder to clion – just to remove version from it
sudo mv /opt/clion-2016.1/ /opt/clion
