How to set the compiler path in Linux

Article Title: several methods for setting compiler paths in Linux. Linux is a technology channel of the IT lab in China. It includes some basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Assume that your compiler is 2.95.3 under the/usr/local/arm directory.

Method (1): directly input the code in shell. After the path is set, the setting takes effect immediately. After the current shell is turned off, the setting fails.

Export PATH =/usr/local/arm/2.95.3/bin: $ PATH

Method (2):/* after the path is set, it takes effect after the environment variable is re-read, but the setting is still valid when the current shell is turned off */

Vi/etc/profile

Pathmunge/usr/local/arm/2.95.3/bin

Method (1) is valid for the current user.

Vi. bashrc

Export PATH =/usr/local/arm/2.95.3/bin: $ PATH

Method (2) is valid for all users.

Vi/etc/profile

Pathmunge/usr/local/arm/2.95.3/bin
