_ mruby on zaurus

軽量rubyらしい。zaurusで動けば嬉しいのだが...

gcc -Wall -Werror-implicit-function-declaration -g -MMD -I../../src -I../../src/../include -c ../../src/st.c -o ../../src/st.o
../../src/st.c: In function 'st_hash':
../../src/st.c:1053: error: 'SIZEOF_ST_INDEX_T' undeclared (first use in this function)
../../src/st.c:1053: error: (Each undeclared identifier is reported only once
../../src/st.c:1053: error: for each function it appears in.)
make[2]: *** [../../src/st.o] Error 1
make[1]: *** [../bin/mrbc] Error 2
make: *** [src/mrblib/mrblib.o] Error 2

SIZEOF_ST_INDEX_Tがどこにも定義されていない?

解決

Mac OSXでも同じ状況だった様子。対応がめちゃくちゃ早い。

また引っかかった

リンク段階でエラー。

実は少し前の段階で

セグっている。なぜ?

とりあえずgdbをかけた結果を貼っておく。

解決！(2012.6.29 追記)

#define ALLOC_ALIGN 4

を、src/pool.cの先頭に追加で解決(^^)d
