Environment Modules简单使用

Environment Modules(简介)[http://modules.sourceforge.net/]

Typically users initialize their environment when they log in by setting environment information for every application they will reference during the session. The Environment Modules package is a tool that simplify shell initialization and lets users easily modify their environment during the session with modulefiles.

初始化

刚刚安装好的Environment Modules是没有module这条shell命令的
需要进行简单的配置source一下环境

在profile.d下建立软连接，执行下列语句

# root用户
$ cd profile.d
$ ln -s /usr/local/Modules/init/profile.sh
$ ln -s /usr/local/Modules/init/profile.csh

# 普通用户
$ source ~/.bashrc

管理工具的不同版本

一个简单的例子

$ cd /usr/local/Modules/modulefiles
$ mkdir riscv_toolchain
$ cd riscv_toolchain
$ touch compile-version
$ touch freedomstudio-version

compile-verison

#%Module1.0######################################################################
##
## riscv-toolchain modulefile
##
proc ModulesHelp { } {
    puts stderr "\tThe riscv-toolchain compile version Module\n"
    puts stderr "\tThis module adds the current working directory to your path."
}

module-whatis   "adds  /opt/riscv/toolchain/bin to your PATH environment variable"

conflict        riscv_toolchain/freedomstudio-version

set             riscv_home      /opt/riscv/toolchain
setenv          RISCV           $riscv_home

append-path     PATH            $riscv_home/bin
append-path     LIBRARY_PATH    $riscv_home/lib
append-path     LD_LIBRARY_PATH $riscv_home/lib
append-path     LD_INCLUDE_PATH $riscv_home/include
append-path     MANPATH         $riscv_home/share/man

freedomstudio-verison

#%Module1.0######################################################################
##
## riscv-toolchain modulefile
##
proc ModulesHelp { } {
    puts stderr "\tThe riscv-toolchain compile version Module\n"
    puts stderr "\tThis module adds the current working directory to your path."
}

module-whatis   "adds /opt/FreedomStudio/SiFive/riscv64-unknown-elf-gcc-8.3.0-2019.08.0 to your PATH environment variable"

conflict        riscv_toolchain/compile-version

set             riscv_home      /opt/FreedomStudio/SiFive/riscv64-unknown-elf-gcc-8.3.0-2019.08.0
setenv          RISCV           $riscv_home

append-path     PATH            $riscv_home/bin
append-path     LIBRARY_PATH    $riscv_home/lib
append-path     LD_LIBRARY_PATH $riscv_home/lib
append-path     LD_INCLUDE_PATH $riscv_home/include
append-path     MANPATH         $riscv_home/share/man

简单使用

$ which riscv64-unknown-elf-gcc
riscv64-unknown-elf-gcc is /opt/riscv/toolchain/bin/riscv64-unknown-elf-gcc

$ module load riscv_toolchain/freedomstudio-version 
Loading riscv_toolchain/freedomstudio-version
  ERROR: riscv_toolchain/freedomstudio-version cannot be loaded due to a conflict.
    HINT: Might try "module unload riscv_toolchain/compile-version" first.

$ module unload riscv_toolchain/compile-version 

$ module load riscv_toolchain/freedomstudio-version 
$ which riscv64-unknown-elf-gcc
riscv64-unknown-elf-gcc is /opt/FreedomStudio/SiFive/riscv64-unknown-elf-gcc-8.3.0-2019.08.0/bin/riscv64-unknown-elf-gcc

个人环境管理

$ cd ~/
$ mkdir privatemodules/

~/privatemodules/ 与/usr/local/Modules/modulefiles一样可以包含local的环境设置
