Ruby On PSP

今天下午刚调通，cross compiling + 自己hacking ruby的代码，比想像中简单得多。原以为要重新整理内存布局，白白对着日文的ruby hacking guide看了一遍ruby的gc,eval。附件是ruby代码的patch, 下一个干净ruby source code，打上patch，按下面的方法编译：

./configure-psp
make -f Makefile.psp
cd psp/sampel
make

然后把相应的EBOOT.PBP等文件和测试脚本仍到PSP/GAME(GAME150)就行了。编译之前需要安装psp-gcc和toolchain，PSP需要3.03-oe或native 1.5

patch 我也提交到ruby forge了
https://rubyforge.org/tracker/index.php?func=detail&aid=8134&group_id=426&atid=1700

不过以目前的程度补进ruby core是没太大的希望，下面准备继续把psp sdk包成ruby ext module。

能详细介绍下你的这个东西么？干什么用的
在psp上跑ruby的脚本？

刚去看了你的介绍，很酷~~
太有用了，我爱psp,也爱ruby,你让我的爱统一了，哈哈

请问，这个东西对ruby支持的程度有多少?
是否所有的标准库都能跑？
如果不能跑所有的，那么哪些能跑？

今天晚上做了一个简单的测试，就是把ruby自己带的unit test跑了一下。当然了，首先是要保证core的测试正确，目前结果

250 tests, 2137 assertions, 0 failures, 23 errors

主要错误集中在pipe，file i/o（因为底层有几个函数我直接给的dummy implementation）。

速度是

Finished in 22.615069 seconds.

不知道如果改成native thread会由多大提高。或者改用YARV，YARV据称提高50倍，那样的话，速度就可以接近pc上直接解释的ruby了。
