Test whether the installation is successful. At this point, the installation of the cross compilation environment is complete.Ĩ. Check whether the path is added to PATH (this step is not done, step 8 also shows that the installation is successful)ĭisplay content/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/arm/4.4.3/bin The path of the cross compiler has been added to the PATH.

To make the new environment variables take effect immediately, without restarting the computer, there are 3 methods corresponding to step 5ħ. Register the environment variables (this step is not done, and step 8 also shows that the installation is successful) It is very troublesome to output the file name, so add it to the path to let the computer know where the program is.Ħ.

If the environment variable is not added above and the program of arm-linux-gcc is to be run, the full path of arm-linux-gcc must be written out every time./usr/local/arm/4.4.3/binarm-linux-gcc file name-o Users can better run processes by setting environment variables. What are environment variables? For example path, when the system is required to run a program without telling it the complete path where the program is located, the system should search for the program in the path specified in path in addition to searching for the program in the current directory.

Method 3: Modify the/etc/environment file Increase the path setting, add the following at the end:Įxport PATH=$PATH :/usr/local/arm/4.4.3/bin Method 2: Modify the/etc/profile file (this file is a system-level environment variable, The things set in it are applicable to all users) Methods ) Method 1: Modify the/etc/bash.bashrc file (this file is only applicable to the current user)Īdd at the end export PATH=$PATH:/opt/FriendlyARM/toolschain/4.4.3/bin (path) (note that there is no space on the equal sign) (I have only used the first method to do it, and I have not tried the other Some people have tried it on UBUNTU 11.10 and they are feasible. There are a total of three methods below. There are many ways to modify environment variables on the Internet. Sudo cp -r/opt/FriendlyARM/toolschain/4.4.3/usr/local/arm

#Iask ishare install

Executing this command will install arm-linux-gcc to the/opt/Friendlyarm/toolschain/4.4.3 directory. Note: there is a space after C (not required), and C is uppercase (required), it is the first letter of the English word 'Change', in This is the meaning of changing the directory.

Sudo tar xvzf arm-linux-gcc-4.4.3.tgz -C/ After decompression directly, -C/will automatically place the decompressed files in the specified path in the root directory, don’t worry)ĭownload arm-linux-gcc-4.4.3.tgz to any directory and enter this folder
