Environment setting script

で、この前の続き・・・かな。

私は"linux-research/targets" folder の下にテストしたい環境ごとに
ちょっとだけ違ったものを並べている。
んで、環境変数設定は人間が毎回手でやるとミスが起きるので
Scriptにしてある。

linux-research/

    

    
-- add-dev-env
    
    

    
-- targets/
    
    

    
   
    
-- beagle-preempt/
    


    

    
   
    
-- mips-landisk/
    
    

    
   
    
   
    
-- env-override
    
    

    

    
"linux-research/add-dev-env"と"linux-research/targets/${target_name}/env-override"の２種。
"env-override"は、必要ないtargetには入っていない。

"linux-research/add-dev-env"は以下の内容。
#!/bin/bash

        echo -e "[Yes]"
        source "${BLDROOT}/env-override"
else
        echo -e "[No]"
fi

見てて何か気づいた人は「組み込みlinuxシステム構築 第一版」で勉強した人ですね（ｗ
ISBN:9784873111612
(２版がでているらしいが未チェックだなぁ)


"env-override"は以下
export CROSS_COMPILE="mips-linux-"
echo -e "\tCROSS_COMPILE=${CROSS_COMPILE}"

export XTOOL_ROOT="${PRJROOT}/xtools/mips-2008q3"
echo -e "\tXTOOL_ROOT=${XTOOL_ROOT}"

export XTOOL_BIN_PATH="${XTOOL_ROOT}/bin"
echo -e "\tXTOOL_BIN_PATH=${XTOOL_BIN_PATH}"
こんな感じで。

作業開始前に
$ cd ~/linux-research
$ source add-dev-env
ってな感じで使う。
