Build Cross Toolchain for ARM - Trial 3 - Cross Toolchain success

繼續，上次build cross toolchain，改用gcc-3.3似乎OK。
但是build到gcc時，出現compiler error ! Q_Q...
猜測大概是使用unstable的關係，
重新install debain，使用stable.

$gcc -v
gcc version 3.3.5 (Debian 1:3.3.5-13)

---

需要sudo : aptitude install sudo.
修改sudoer : ref 前一篇

wget http://kegel.com/crosstool/crosstool-0.38.tar.gz

unpack，follow doc/crosstool-howto.doc動作，create /opt/crosstool, chown.
開始

$sh demo-arm.sh

出現

tar: bzip2: Cannot exec: No such file or diectory

是沒裝bzip2的關係。

$sudo aptitude install bzip2

繼續...把build log copy一份到~/corss.txt

$sh demo-arm.sh 2>&1 | tee ~/cross.txt

10:16開始...10:54 結束.. Error : 和當次build時一樣。
在" Build final gcc " Stage. make all中 libiberty 目錄，使用build好的xgcc build cp-demangle.c時發生，log:

Google一下，這是很多人都發生的問題 (應該先看一下的)，reference 這一頁。有test build statu，選一個OK的，latest one :

gcc-4.0.1
cgcc-3.3.6
glibc-2.3.2
binutils-2.16.1
linux-2.6.11.3
hdrs-2.6.11.2

但是dem-arm裡沒有

crosstool 中gcc.dat有更新的0716.修改demo-arm.sh，改用20050716，再執行一次 11:35...download 0716 snapshoot... (到ftp://gcc.gnu.org/pub/gcc/snapshot去看，可以看到其實gcc 最新是1015)。....12:20開始build.....12:55 OK! Success !!!!!!
所以只要用修改demo-arm.sh，用

 eval `cat arm.dat gcc-4.1-20050716-glibc-2.3.2-hdrs-2.6.11.2.dat`  sh all.sh --notest

就可以。

<其他>
follow getandpatch.sh，發現自動fetch source的code，到gcc.gnu.org去拿source。由***.dat定義的version name去拿資料。
4.0 版snapshot後面會接上snapshot的日期：例如4.0-20051017
release的版本則會加一個小的版本號：例如4.0.1, 4.0.2
getandpath.sh 中，4.0版的gcc到prelease去拿，但是現在已經放在release下了。
