reopen - ViewML, libwww and flnx

上一次的build (http://checko.blogspot.com/2006/01/viewml-open-source-web-browser-for.html) 已經寫不下去。所以由 ：http://my.clubhi.com/bbs/661523/messages/21263.html 來看，用一些比較舊的版本(flnx-0.16.tar.gz
viewml-0.22.tar.gz)來試試(或許可以避掉 " unrecognizeable insn" 的compiler 問題。

先紀錄一下上次做到的階段:

• libwww - cross configure 要修改的部份已經了解(再確認long double的意思就可以)
• flnx - make fuild 時碰到 "unrecognizeable insn" error : 無解（改source或upgrade to 2.96 )
• viewml - config 部份似乎ok - 缺libwww config 讀取部份.

從ftp site 各package 的 timetag來看。
libwww 應該是最穩定的--- 只有一版 2000/08/22
其他viewml 和 flnx 的最後三版，似乎對應著開發時間-- 是不是要一對一的使用?


所以，還是從最stable的libwww開始build --

上一篇提到的 long double 選項是yes還是no : 拿 pc 作reference :
double : 8
long double : 12
===> for long double 的選項是yes.
用arm-elf-gcc run出來的
double : 8
long double : 8
所以選項應該要是no

難怪configure 的test program是：exit (sizeof(long double) < ( sizeof(double) )

修 改好configure script ..開始configure :

$ CC=arm-elf-gcc CXX=arm-elf-g++ NM=arm-elf-nm AR=arm-elf-ar ./configure --host=i686-pc-linux-gnu --prefix=/home/charles/sigma/libwww --disable-shared 2>&1 | tee output

OK.
接著

make 

成功！沒有任何error. 再

make install

完成！

重點就在指定CC,CXX,NM,AR等tool和修改configure 這個script讓她可以產生cross-compile Makefile.

以下附上configure script的patch，copy 後rename為到w3c-libwww-5.2.8 的目錄下，用

$ patch configure configure.arm.patch

就可以.
