※下準備：gmp-4.2とmprf-2.3.1をインストールしておく。
現時点でのgccの最新版は4.3.1とのこと
とりあえずgcc-core-4.3.1.tar.gzを入手
あとは以下を参照
Installing GCC: Configuration
・・・英語読めない orz
とりあえず、ディレクトリを分けたほうが良さそう。
ソースを展開し、workdirを別に作成
/home/work/gcc/ # tar zvxf gcc-core-4.3.1.tar.gz /home/work/gcc/ # mkdir workdir /home/work/gcc/ # cd workdir/ /home/work/gcc/workdir # ../gcc-4.3.1/configure /home/work/gcc/workdir # make
すると、
... checking build system type... armv5tejl-unknown-linux-gnueabi checking host system type... armv5tejl-unknown-linux-gnueabi checking target system type... armv5tejl-unknown-linux-gnueabi checking LIBRARY_PATH variable... contains current directory configure: error: *** LIBRARY_PATH shouldn't contain the current directory when *** building gcc.

ありゃ。LIBRARY_PATHってのがよろしくない？
unsetしてみる。
/home/work/gcc/workdir # unset LIBRARY_PATH /home/work/gcc/workdir # make
今度は順調
・・・と思いきや。

"CHAR_BIT"が宣言されていない？
よくわからないけど、line-map.hを勝手に書き換えて"limits.h"をincludeしてみる。

さっきよりは進んだ！
・・・が。

また"CHAR_BIT"か・・・
懲りずに今度はreal.hを改変
/home/work/gcc/workdir # cd ../gcc-4.3.1/gcc/ /home/work/gcc/gcc-4.3.1/gcc # cp real.h real.h.bk /home/work/gcc/gcc-4.3.1/gcc # vi real.h (ごにょごにょ) /home/work/gcc/gcc-4.3.1/gcc # diff real.h real.h.bk 30,31d29 < #include <limits.h> < /home/work/gcc/gcc-4.3.1/gcc # cd ../../workdir/ /home/work/gcc/workdir # make
さぁ、今度はどうだ・・・？

んんん・・・今度はまたちょっと違う。
調べてみると、"Installing GCC: Configuration"でconfigureのオプションに書いてあるっぽい。
--enable-decimal-float
--enable-decimal-float=yes
--enable-decimal-float=no
--enable-decimal-float=bid
--enable-decimal-float=dpd
--disable-decimal-float
Enable (or disable) support for the C decimal floating point extension that is in the IEEE 754-2008 standard. This is enabled by default only on PowerPC, i386, and x86_64 GNU/Linux systems. Other systems may also support it, but require the user to specifically enable it. You can optionally control which decimal floating point format is used (either `bid' or `dpd'). The `bid' (binary integer decimal) format is default on i386 and x86_64 systems, and the `dpd' (densely packed decimal) format is default on PowerPC systems.
よく分からないけど、玄箱ProはARMアーキテクチャだから、このへんはサポートされないってことなのかな。
/home/work/gcc/workdir # make distclean /home/work/gcc/workdir # rm stage_final /home/work/gcc/workdir # ../gcc-4.3.1/configure --enable-decimal-float=no /home/work/gcc/workdir # make
とやってみたが、結局変わらずorz
どうすりゃいいんだろう〜
binutilsを新しいの入れたら変わるかな、と最新版をインストールしようとしてみたらmakeが失敗してtexinfoが必要なのかな？とtexinfoを入れようとしたら今度はconfigureがうまくいかなくてgawkやらbashやらを新しく入れてみたり。
なんだかどんどん遠ざかっている気がする。。。
